Deaf dogs are no different than hearing dogs. Dachshunds are often one person dogs, and are known for being snappy. Mine are perfectly tolerant towards kids, though Boo growls when more than one person touches him... it's just kinda his thing. He was spoiled rotten for 6 years before going to rescue, so he's needed alot of re-training. Mouse is the sweetest dog, and would never bite or growl.
