Q:

Do deaf dogs bark?

A:

Although the frequency varies depending on the individual animal, deaf dogs can and do bark. They do not bark in response to auditory stimuli like dogs with normal hearing, but they may bark at visual stimuli or at sounds that they can still hear if they are not fully deaf.

Prolonged or unusual barking can be a symptom of adult-onset deafness as the dog attempts to compensate for hearing loss. Although barking does serve a communicative purpose, it is also an instinctive behavior rather than a learned language; dogs who were born deaf may bark in the right circumstances. Deaf dogs often bark less than other dogs.

  • Q:

    How do you train a deaf dog?

    A:

    Training a deaf dog is not all that different than training a hearing dog, says Deaf Dog Education Action Fund. The basic principles are the same. The dog has to be taught the meaning of a signal the owner gives. The only difference is that hearing dogs can be taught to respond to noises as signals and deaf dogs cannot. The first step in training a deaf dog is teaching the dog to look at the owner in response to a vibrating collar. Once the dog can look at the owner on cue, the dog can be taught to follow hand signals for all other basic obedience commands.
