Bull Terrier Question

If a bull terrier is deaf it would have been born deaf, your puppy should have the BEAR (hearing testing) done and you should get a copy of the BEAR testing with the results. I know of deaf bullies and have never heard of them being aggressive due to deafness.

I have a 6mo old bullie female, she was born deaf. She was alittle harder to train but she is very sweet towards people. And she does fairly well around other dogs.

What Belle7 is trying to tell you about is actually called a BAER test (brainstem auditory evoked response) not a "BEAR" test. A BEAR is an animal that lives out in the woods. Deafness is a genetic disorder associated with Bull Terriers. Breeding white on white or having too many white anchestors within the 4 generation pedigree can heighten the chances of this disorder. Conduct proper research on reputable breeders to ensure you're getting one from a breeder that tests for ALL disorders associated with the Bull Terrier breed.
