We had bull terriers, and I named my black and white one, Tux - Andifar Formal Apparel.
Deaf dogs can be taught Sign Language. Lots of Boxers, Bull Terriers and Dalmations are unilaterally or bilaterially deaf (one ear or both). It is genetically linked to the white gene and due to missing pigment in the inner ear. Kansas St Vet School is where I took all of my puppies to be hearing tested prior to placement. Please be sure to microchip your dog and never, ever let him off of a leash out in the world. Good luck and enjoy this little guy. He will get great joy learning to communicate with you and you with him.
