Deaf Dog Border Collie Observations & Comments
Hal Gale, PhD, August 2010
These ‘Observations and Comments’ combine illustrative personal observations of a deaf Border
Collie (BC) dog and her hearing mother in our home and vicinity, with an collection of anecdotes from
the DeafDogs Yahoo Internet group. Section 4 lists ‘best’ books and training DVDs. Our deaf BC is a
spayed female three and a half years old. She was born on a sofa in our home, raised under our
kitchen table and in the immediate surrounding areas. Her deafness was confirmed by empirical tests,
such as her failure to react promptly to loud noises near her, by age eight (8) weeks. Both her mother
and father possessed a ‘white-merle (risk) factor’ such that one or more of their pups possibly would
be one-ear deaf or totally deaf (both ears). Possible deafness would be preliminarily indicated if the
respective puppies were almost totally white color and later as they grow up exhibit a black-spotted
light colored coat (Dalmatian style “freckles” or “merle” coat).
Although until recently popularly mislabeled “a deaf-white gene,” white coat color is not always the
case. What is the case is that for deaf puppies, with BC’s it is that areas around the head and ears,
are white but they can have a lot of black on their backs. With Australian Cattle dogs, the coat is very
light colored, blue or red, not dark, and deaf cattle dogs have virtually no spots or patches on them
despite the presence of the high probability of deafness Dalmatian gene that brought in deafness
when the Australian Cattle dogs breed was being made. For Koolies it is the merle gene.
To learn from the experience and observations of other owners of deaf dogs, I joined the DeafDogs
Yahoo Group that as of July 2010 had 3,250 human members. Membership required owning a deaf
dog. The dog’s deafness might be a result of causes such as a genetic birth defect, old-age, disease
or an accident. Membership was world-wide: Australia, US, etc. Because many members had both
hearing and deaf dogs, and some members had two or more deaf dogs, the dogs represented in total
probably exceeded 4,000 dogs. It is likely that all of the major dog breeds were represented. The
Group’s viewpoint and conclusions about deaf dogs are well summarized in a paraphrase from a
Deaf dog mantra: 1. It’s a dog, 2. It has a breed and the breed traits, 3. It has its own
personality, and 4. Way way way way last, - deaf with ears that are ornaments!
Many unpleasant misleading or false myths exist about deaf dogs. According to various Internet
reports, the US AKC currently (2010) discriminates against participation of deaf dogs in their main
activities. Our experience indicated that, among the general public, the representative forms of
negative emotional reaction against deaf dogs ranged from expectations of severe mental incapacity to
at best irrational expectations of viciousness. The most common reaction was to treat a deaf BC as a
“Throw-away” toy to be used up and discarded, or discarded immediately. As documented via the
Yahoo Group and my observations, nearly all of the myths are misleading with a tiny kernel of fact or
entirely false. Except for using conventional ear-hearing, deaf dogs are capable of all activities of
hearing dogs. In addition, some deaf dogs engage in activities that may be unusual among hearing
dogs. Further, living with a deaf dog reportedly often enhanced the lives of their humans.
1. An Insight to Human-dog Mutual Behaviors - Paraphrased From ‘DeafDogs’
Some humorous mostly true observations were compiled by DeafDogs list members: You Know You
Have A Deaf Dog When ...
Your dog ignores you (just as hearing dogs do) by turning her head away, but for her shouting doesn’t
help at all.
Your dog doesn't care if her favorite toy has a ‘squeaky’ or not. But she discovered that the squeaky
ball really irritates her hearing mother!
Your dog likes to lie on your feet or across the doorway, so that you can't leave the room without him
knowing. [Labeled ‘velcroing’]
Instead of listening for your car, your dog watches for headlights on the wall and can tell your car’s
lights from your spouse's.
You flash the porch lights on/off for your dog, rather than for your teen-ager.
Stomping on the floor doesn't mean you’re angry.
You notice Christmas bells in the craft store and immediately think "What a great size for the dog's
collar!" and buy a box of 24.
Your first thought when you see a new dog sport or trick is "hmmmm - I wonder what would be a good
signal gesture for that?"
You walk though the house waving a dog bowl when it's time to eat.
You are the only one at the dog park "calling" your dog back by waving your arms over your head.
And when she doesn't come, you "wave louder."
You find yourself looking at the sky, ceiling, etc., trying to figure out what it was that your dog saw there.
Praising or scolding your dog consists of wildly exaggerated (and very comical) faces and hand
Your dog watches your hands intently, trying to decide if you’re talking to him and what the motions
You inadvertently train your deaf dog to do something weird, because a habitual gesture you use all
the time caught her attention.
People are impressed that your dog knows so many hand signals - until you tell them that he is deaf.
The first question you receive regarding your deaf dog is "does she bark?" (And then you can amaze
them by turning to your dog and signaling her to bark, which she does quite well.)
People argue that your dog can’t be deaf, he's paying very good attention, is responsive and well
trained, and his ears move.
You unintentionally do your "good dog" hand signal to your coworkers, spouse, dogs and cats.
You find yourself making exaggerated hand and arm motions to get any dogs' attention, instead of
making kissy, smoochy noises.
You ask them to sit or lie-down with your hand instead of your voice.
You and your spouse can communicate silently in public by using your dog's signs.
You can sign "sit" and your dog and kids will all sit and look at you.
You've learned to do sign language and shift gears at the same time while driving.
Your dog trainer stops talking to the hearing dogs, too.
Your other dogs learned all the deaf dog's hand signals by osmosis. Not only that, but they wait for the
hand signal after the vocal cue, like they don't believe you really meant it until they see the signal.
You can open a crinkly snack bag and your dog doesn't notice till the smell reaches her.
Your dog either ignores the vacuum-cleaner sounds or thinks it's a great thing to play with.
You don't have to spell W-A-L-K or S-Q-U-I-R-R-E-L or B-A-L-L when talking in front of your dog.
You can sing off key and your dog doesn't howl.
You talk on the phone and to your dog without a breaking the conversation. The same for a sore
If your dog doesn’t greet you as you come home from work, you can participate in a game of "where's
the dog sleeping now?"
You can enter your house with an armload of groceries, sneak into the kitchen, and unload them - all
before your dog knows you're home.
You can get up to go the bathroom in the middle of the night and your dog doesn't wake up. If you are
really sneaky, you can get up and be completely ready for work before letting your dog out of her crate.
You can play possum and not have to get out of bed so early in the morning if your dog just doesn't
see you move or open your eyes.
You can look forward to July 4th and New Year's Eve because the noise doesn't bother your dog. It
also doesn't take hours to coax your dog out from under the bed after a thunderstorm. Your dog has
no noise anxiety!
When someone rings the doorbell, your dog continues to sleep (people think he's so well-behaved).
You can walk your dog down the street without stopping as the neighbors' dogs bark while you pass by.
Dogs can bark right outside your house and your dog will go right on sleeping.
When the "Twilight Bark" starts up, it skips your house. On the other hand, your dog will wake up in the
dead of night to bark at a light she saw, and upset the dogs in the neighborhood for nothing.
Your hearing dog apparently for amusement stands directly behind the deaf dog, and in a series of
barks escalates the volume until the deaf dog wriggles her ears and looks back for the dog who has
Your neighbors and friends long ago forgot which of your dogs is deaf, and so speak and sign to both.
Your deaf dog makes unusual (for her breed) verbal sounds when excited or dreaming, such as 1)
yodeling, 2) mooing like a cow, 3) screaming like a banshee when she gets too excited to remember to
bark like a hearing dog.
Your deaf dog is fascinated by human ears, and investigates them when she can, but ignores the ears
of other dogs.
Summary: Deaf dogs have ears for ornaments, and are otherwise normal. Their humans if decent
people, accept and enjoy the unique aspects of living with a deaf dog.
2. Kernels of Truth about Deaf Wee Puppies and Juveniles
Ear-Hearing is apparently important to early socializing of puppies: As described by Scott and
Fuller, 1965, puppies learn from each other about the age of three to eight weeks that they must use a
soft-mouth [gentle-inhibited bite]. K Lorenz, “King Solomon’s Ring”1952 and “Man Meets Dog” 1953
mistakenly believed that an inhibited bite was exclusively an evolution-fixed action pattern (FAP)
genetic instinct like imprinting among certain birds. He was wrong, as documented in 1965 by Scott and
If a puppy is unable to hear the screams of its play-victims, and its own screams when play-bitten with
needle sharp puppy teeth, it may less quickly learn to use an inhibited bite. Thus a deaf puppy is at
risk of being less well socialized, abused by sibling puppies as a rough social deviant, and either timid
and passive or oppositely chasing and mistreating other puppies. A knowledgeable dog-mother such
as Lace with her third litter of puppies used parenting to instill proper social behavior in a hearing or
deaf delinquent puppy, or a knowledgeable human can participate in the parenting to ensure all of the
puppies learn to use an inhibited bite and treat each other decently.
Unfortunately neither puppies nor human babies arrive with an owner’s manual, so occasional first time
mothers are less effective in educating their offspring to use an inhibited bite and play nicely together
without bullying. Our experience with Border Collies suggested that at any age dogs are able to learn
an inhibited bite and appropriate dog-dog behavior. However, a 100 pound human trying to teach a
75 pound juvenile dog to stop doing excessively fierce nipping and biting may perhaps find herself
engaged in a difficult process if the dog has learned to enjoy controlling the actions of other dogs and
humans. In such instances, regardless of whether the dog can hear or is deaf, the aid of a
professional trainer accustomed to educating poorly socialized large dogs should be sought.
Startle Reflex Education: Dogs and humans who are unexpectedly touched, or even worse –
kicked - will characteristically react with a ‘startle reflex’ by looking around and possibly instinctively
defending itself against an apparent ‘attacker.’ Ordinary ear-hearing puppies quickly learn that
sudden noises and touches typically are a sign that something good is about to happen, such as
breakfast with mother. A deaf dog also can quickly learn that being startled is good.
Properly raised puppies teach each other to react with inhibited bites to sudden touches, and that
even being knocked over isn’t a satisfactory excuse to abruptly severely bite somebody. BC puppies
we observed began about an age of four weeks playing learning-games that we called “puppy
bumping.” Apparently for play-amusement, a puppy ran across the floor to collide with and knock an
unsteady sibling off its feet. Sometimes a ‘tussle’ ensued with the puppy play-attacker and the play-
victim engaging in much mutual vocalizing, nips and exchanges of ear, fur and tail pulling.
Thus a deaf puppy may be educated by its siblings to react enthusiastically and happily by nipping at a
presumed play-attacker when as a “play-victim” the deaf puppy is startled from a sound sleep, or
caught in a position where it didn’t see the attacker arriving. If a deaf puppy isn’t socialized to
manage its startle reflex, it might have a tendency to embarrass itself by nipping at a friendly human
who touches it to wake it up for its dinner. Numerous if not quite all deaf dogs as reported on the
Internet are easily educated that any sudden disturbance is probably a clue that something nice is
about to happen.
An exception was of course the reports of deaf puppies and juveniles who were taught by a human that
a startle-sudden disturbance means they are about to be severely kicked or injured. Eventually
perhaps mistreated puppies will defend themselves, run away, or die. People with deaf dogs
DELIBERATELY wake and train their dogs to wake up happy and to never wake up and nip anyone.
‘Velcroing’ by deaf dogs and seeking to calm their startle reflex: Our deaf BC, and according to
reports on the Internet most other deaf dogs, discover a technique that humans call ‘velcroing.”
Typically a deaf dog as a juvenile, and some as adults, chooses when sleepy or asleep to keep direct
physical contact with their favorite human or a chair the person might be sitting on. The deaf dog has
learned that the slightest movement of the person or the chair signals that something interesting is
about to happen, so the dog should wake up and become alert [The world needs more ‘lerts.] Many
dogs later learn that lying across a door, if that is the main exit/entrance will ensure that the dog
knows when its human goes past. Some humans and other dogs will learn to play ‘games’ on the deaf
dog by sneaking stealthily past the sleeping dog, leaving the deaf dog to awake later and wonder
where the others went. Deaf dogs are typically much attuned with 'air movements' e.g. if the dog is in a
crate and an outside door is opened, the dog will usually wake up because it senses the changed air
movement and human fresh smells.
Non-ear hearing by some deaf dogs: Our deaf BC at about eight months age was observed in the
presence of talking human to stand on a sofa with her forehead lowered to press against the cushion
she was standing on. She had discovered that she could detect and ‘understand’ vibrations by
touching or standing on vibrating surfaces. Later she discovered that she could ‘listen’ to the
vibrations of a telephone-voice-recorder when she played back the recorded messages, with her chin
touching the machine. Similarly she could ‘listen’ to a small radio by placing her chin on the top of its
case. She never placed her chin on those objects unless they were playing voices or radio at a
significant loudness. As anyone might know who has observed ripples on the surface of a beverage in
a flimsy paper cup, or felt with their finger tips the vibrations of a small radio’s case, etc. - sounds can
cause touch and air-movement pressure-touch sensations by moving the skin, fur/hair/clothing,
external portions of ears, and of course dog-whiskers.
Thus owners sometimes confuse themselves into hoping that their deaf-dog has recovered some
hearing, when actually their dog has cleverly discovered that various vibration and pressure
sensations of their body parts have significance about their environment.
Analogously, some blind humans are able to extract information about their surroundings from
comparing the modulation and arrival times of sounds directly received from a source versus those
sounds reflected from the surroundings before the sounds arrive at the person’s ears. Convincing
reports of hound dogs using radar-like location-hearing processes at night were reported on the
Such indirect (not by their inner-ear) detection of sounds by a deaf dog can be mistaken for inner-ear-
hearing if the source of the sounds is a human or another dog at close range- perhaps several feet
away. For example, our deaf BC micturated within seconds of her mother doing so, despite an
absence of sounds and perhaps as much as fifty feet downwind between them. I also observed our
deaf dog being summoned by her mother who stood behind the deaf dog at a distance of about two
feet and barked several times with increasing loudness until her daughter looked over her own
shoulder to see her mother, and hopped up to follow her away. Both non-ear hearing and olfactory
detection of her mother’s dog-breath might have alerted the deaf lass that it was time to move on.
Dog-Human Sign Languages: Puppies learn to understand the body-language, vocalizing and odors
of other dogs, and their humans, much as human babies learn to understand adult humans and
other children. A deaf puppy necessarily omits learning the meaning of inner-ear sounds, and thus
tends to focus on understanding body language, including hand gestures of humans, and olfaction-
smelling. Thus deaf puppies are predisposed to learn from humans a “gesture language” such as
American Sign Language (ASL) or one of ASL’s international variants. A fine trainer, Virginia
Broitman, taught our deaf dog all the basic signs.
Routinely deaf dogs acquire at least an elementary language capability consisting of verbs [get, come,
lie-down, etc], nouns such as ball, Frisbee, rope, names and so forth; and adjectives that describe a
specific noun-object such as for example “short” rope, and “long” rope. Complex gestures such as
those describing a path to be run to get a specific object are routine. Thus human communication to
deaf dogs with a version of sign language is common. ASL is not international, as it is mainly used
in America and Canada. Australia and Britain have a different style of hand-sign language. In
Australia it is called AUSLAN and the hand-signals are different than ASL.
Humans also use their own obedience hand signals, and invent ‘made up’ hand signals. ONE HANDED
signals are best, to always keep one hand free for holding a leash, groceries, etc.
In addition to the ‘classic’ hand sign languages, deaf dogs expect from their humans the important face
and body language, e.g. HAPPY, relaxed, smiling face and a very loose fluid body. Conversely
‘scolding’ is usually done by just using ANGRY, pinched face, glaring eyes and a very ‘stiff’ body
posture. Deaf dogs, like hearing dogs, carefully watch and respond to face and body language,
before we usually even realize.
Reciprocal communication to humans by gesture signing of dogs is feasible and can be routine
although such training of dogs is sparsely documented. The work and publications by Sean Senechal
should be consulted for the best of such research currently known to me. Owners of deaf dogs
reported many casual anecdotes of their customary reliance on ad hoc informal dog-“sign-gesture”/
“body-language”-language dialects mutually developed among the associated humans and dogs.
Dog-dog reciprocal communication using body-language is routine, although some hearing dogs are
said to momentarily experience a little apparent confusion about unusual or unorthodox verbalizing by
deaf dogs when initially encountering a deaf dog. Our hearing BC and her deaf daughter BC
illustrated that. When my deaf BC used inappropriate ‘fierce’ vocalizing at first when engaging in rough
rope-tug play with me, its hearing mother BC scolded the deaf dog, until after several events the deaf
dog softened its vocalizing.
Self-Awareness that a deaf dog is ‘different’: Our daughter, who is deaf in one ear, self-
diagnosed her uni-deaf (monaural) capability at age six years. Our deaf BC as a juvenile between the
ages of two months and 18 months occasionally exhibited behavior that implied that she was aware
that she had different sensory and perhaps physical features. She also exhibited one of the occasional
anecdotes reported of deaf dogs’ behaviors: a fascination with the ears of humans. Usually the subject
human reported sitting or reclining when the deaf dog gently investigated in detail the ears of its
human. Later at random intervals the action was repeated in a way indicating that the deaf dog was
deliberately repeating the actions as ‘play.’
Our deaf juvenile BC routinely accepted that other dogs have an “extrasensory perception” that
permits other dogs to understand what humans want done - commands and events - without looking at
the humans although the deaf dog is apparently unaware of how that is communicated from the human
to the other dog(s). Our deaf BC frequently looks briefly at her humans and the other dogs for clues
about what her behavior should be. For example, when our hearing BC is tracking a squirrel through
the tree tops, the deaf BC is carefully watching the hearing BC to determine what is going to happen
Only our deaf BC has been observed repeatedly as a juvenile doing self-initiated experiments
apparently exploring her three-dimensional (3-D) vision capabilities. To (probably) explore her 3-D
she repeatedly stood where one eye or the other was covered by an object such as the edge of a
door, when engaged in ball-throwing activities with me. When she covered an eye, she had very poor
success in catching a ball tossed in her general direction. Later she began to adopt a posture when I
was about to toss a ball, such that her own muzzle blocked vision by her off-side eye, which of course
would preclude 3-D vision of the early trajectory of the ball and my hand motions. She alternately
blocked an eye with an object or muzzle-blocked with one eye or the other, thus indicating that she was
exploring a ‘one-eye’ aspect of her vision feature-capability. (An eye examination showed that she
had normal vision.)
Our deaf BC was an early “experimenter” on other activities interesting to her. For example, she
discovered that humans can kick the ball with their foot, for her to chase and retrieve. She initially
explored the issue of how far away; perhaps as far as 10 meters outdoors, she could place a retrieved
ball for the human to kick it again. She apparently preferred to force the human to go to the ball,
probably so that she could run to a distance before the ball was kicked, i.e. delaying the kick for her
convenience. She also probably by observation learned that she could place a retrieved ball near a
human on an angle-azimuth to control the direction to where she desired the ball to be kicked. Indoors
she often placed a ball near a person’s foot for it to be kicked, in preference to placing the ball in a
human’s hand. She personally only throws a ball with her mouth, or pushes it abruptly with her muzzle,
and almost never pushes a ball with her paws to make it move to a human.
Our deaf BC later acquired other vision techniques such as the usual “head-tilting” when looking at
nearby humans [taking advantage of the dog-linear high resolution eye-streak; see A. Miklosi]. She
also later used rapid eye “flicking” back and forth between two dynamic objects that interest her, to
keep close track of both objects at the same time. I have never seen her using the eye-flicker to
closely observe more than two objects but suppose that she could do it. Further, on several occasions
while she was “staring” at a herding candidate, as BCs normally do to control sheep, she suddenly
dashed away in fast pursuit of a squirrel that she had seen at the extreme outward angle of her
peripheral vision, and which I had not at first seen. Such extreme sensitivity of the outermost portion of
the linear eye-streak was first called to my attention by the dog-vision remarks provided in A. Miklosi’s
book. The hearing BC had acquired head-tilting and other vision techniques previous to their
rediscovery or mimicking by the deaf BC. [Both BCs use the classic “eye-stare” for herding other dogs.]
Unusual and “classical” vocalizing by deaf dogs: Perhaps it is well known that many deaf humans
may encounter difficulty in learning to speak clearly, because they are unable to perceive the sound of
their own voices. In addition, research of bird songs reported that apparently birds are hatched with a
“template” of the natural songs of their species. Further research demonstrated that juvenile birds
refine their songs by modifying or embroidering their templates on the basis of species songs that they
hear as they mature, with the result that each flock may have a unique song-dialect.
Digital recordings of four (4) litters of BC puppies, by two mothers and three different fathers indicated
that at birth, within seconds, puppies vocalized human-recognizable proto-barks, whines, and “lost-
puppy” chirps, plus miscellaneous trills, humming, et al. Each litter at birth possessed a collection of
vocalizations that was readily distinguishably and unique compared to the other litters. Such birth-
vocalizations within seconds of entering the world, I assume are based on instinctive breed or species
“templates.” Internet reports suggested that some dogs can learn to imitate vocalizing of other dog
breeds, such as reported of a BC raised with raccoon-hunting hounds. Our hearing BC was initially
able to imitate and exchange special vocalizations with other local dog breeds when she was adopted
by us, but apparently gave up that activity when nothing of interest to her was derived from the activity.
Our deaf BC when she is apparently calm and deliberately barking vocalizes much like the barking of
her hearing mother. However, when the deaf dog becomes very excited, she uses high pitched
“yodeling-screams.” As a juvenile she “yodeled” when very excited during play, as for example
running through a water sprinkler. She didn’t observably elevate her head or take a specific posture
When waking up she usually makes a single “mooing” sound of about a second duration, quite like the
“lowing” sounds made by dairy cattle. That kind of vocalizing has been stable for at least three years.
Our hearing BC never vocalizes when waking up from sleep.
Our hearing BC occasionally vocalized while asleep, and almost always used sounds that fit her recent
activities such as chasing squirrels, or playing soccer. The combination of her leg motions and
vocalizations permitted human observers to clearly distinguishable between soccer and squirrel
chasing. In contrast, our deaf dog when asleep occasionally made unique “soft” sounds somewhat like
her moo sounds.
I concluded by observing our deaf BC and our hearing, that BCs probably are born with breed and
species specific templates at least for proto-barking, whines, and “lost-puppy” chirps but can at least
as an adult also learn to vocalize other sound patterns, even imitating human words and phrases.
3. Other deaf-dog activities
General social behavior of the deaf BC was similar to that of our hearing BC, and closely agreed with
the discussion in the research paper “The Social Organization of the Domestic Dog” by Alexandra
Semyonova, available here at Nonlineardogs.com.
No unusual activities of the deaf BC involved smell-olfactory actions. The basis, if any, of a deaf BC
dog’s possibly being more or less interested in smells than a hearing BC couldn’t be evaluated.
Deaf dog ear ‘motions and postures’ signifying their direct of interest, intensity of attention, etc were
indistinguishable from the comparable actions of hearing BCs.
Our deaf BC and our hearing BC quickly learned to remain within their unfenced yard, which is
bordered on two sides by heavily traveled sidewalks and suburban streets. Both dogs routinely
attempted to persuade passing adults and children to participate in a game of soccer.
Although Internet reported anecdotes plausibly suggested that deaf dogs can be trained more easily
than hearing dogs of the same breed, I didn’t observe a significant difference in ease of training
between the deaf and the hearing BC; both learn quickly. Our deaf dog received all her basic sign
language training from human females and at age three+ years she continues to learn more quickly
Deaf dogs in Australia are not discriminated against as is done by the US AKC. In Australia deaf dogs
can compete at all levels in all dogs sports, e.g. obedience, rally, agility, herding, tracking, Frisbee,
pointing/ gun dog, lure coursing, etc. and also as therapy dogs. It shows the AKC and its people how
backward that organization appears to be for deaf dogs and their humans. Also a deaf border collie
competed at CRUFTS in the United Kingdom in agility in 2010. They are events and things that will
encourage people to ‘THINK’ and that is needed to permit deaf dogs to live and perform with their
humans as thoroughly and happily as hearing dogs with humans.
