This poor dog gets caught in a fence after trying to jump over... Watch what happens next : )
Here is a deaf White Pitbull below who still knows her tricks.
One way to find out if your dog is deaf is to see how it reacts when it is sleeping. If you've noticed that when calling it's name you are not getting any response. Try calling its name in a dark room. If your dog still does not respond turn on the light, if it's ears and or head perks up. Your dog may be deaf.
