How To Tell If Your Dog Is Deaf. If he becomes deaf, he’ll still understand your commands. If your dog is deaf, don’t feel bad.

Specific tests (bear) should be performed in potentially affected breeds to know for sure. One of the most obvious signs is that they don’t respond when called from a distance, and often wander off or bark at nothing. If the dog has partial deafness, it will look in the opposite direction and not from the source of the sound.
