Deaf dogs can make great pets. They adapt to their hearing loss quite well because a dog’s primary sources of communication are body language and scent. You might notice that when two dogs greet each other, they communicate all kinds of signals to each other without using any sound.
While barking and growling are additional ways dogs send messages, they aren’t their primary method. So in training, too, verbal language isn’t necessary. In fact, dogs pay more attention to cues in our body language and facial expressions than to what we are saying to them.
