When Susan Cope Becker bought a cute Boston terrier puppy in 1995, she was shocked several weeks later to discover the puppy was deaf. She was even more surprised when she couldn't find any information on caring for or training a deaf dog.
Becker started researching the issue and ended up writing a book on the topic. Today, there's a good deal of information out there about living with a deaf dog. There are groups, web sites, books, and trainers who work with non-hearing dogs.
Dogs are very expressive animals. They communicate when they’re feeling happy, sad, nervous, fearful and angry, and they use their faces and bodies to convey much of this information. Dog body language is an elaborate and sophisticated system of nonverbal communication that, fortunately, we can learn to recognize and interpret. Once you learn how to “read” a dog’s postures and signals, you’ll better understand his feelings and motivations and be better able to predict what he’s likely to...
"The opportunities for deaf dogs today are so much better," Becker says.
What causes deafness in dogs?
Some puppies are born deaf, which is known as congenital deafness. Other dogs can go deaf from a variety of causes, ranging from chronic ear infections or injuries to drug toxicity and old age, says George M. Strain, PhD, a leading veterinary researcher on the causes of deafness in dogs and a professor of neuroscience at the School of Veterinary Medicine, Louisiana State University.
Are some dogs more likely to be born deaf?
Strain says he has identified 89 dog breeds with incidences of congenital deafness, some much higher than others. Dalmatians seem to be the most at risk, he says, with 30% of puppies born deaf in one or both ears.
Other breeds with higher incidents of deafness include the bull terrier, English setters, Australian cattle dog, the Catahoula Leopard dog, whippets, and Parson Russell terrier (formerly known as Jack Russell terrier.)
Strain says although researchers still aren't sure what causes congenital deafness, they do know it's most common in dogs with white or nearly white heads.
"The lack of pigment on the head causes the pigment cells in the inner ear to fail to develop, or they may be lacking entirely," Strain says. "The lack of pigment cells causes the death of the nerve cells that need to develop for hearing to occur."
Oddly, some solid white dogs, such as the Spitz or the Samoyed, have no problems with deafness, he says.
