That's really good for you! But may I say this: NEVER BUY A DOG/PUPPY OR A CAT/KITTEN FROM A PETSTORE! THEY ARE USUALLY FROM PUPPYMILLS WHERE DOGS ARE MISTREATED!

But you really need to know that owning a deaf dog is a MAJOR resposibility. You can almost never let them out of your sight, especially outside, because they cannot hear you, and if they can't see you, they can't obey. I had a friend that had a deaf dog, and when she was walking her one day, she took off after a rabbit, and slipped out of her collar. The dog was too intent on the bunny, and since she couldn't hear her owner calling to her to stop, ran out into the street and was hit by a car She died instantly

So you really need to think hard about this. It's very difficult to teach deaf dogs commands, so they are often rambuctions, and at risk of getting hurt or killed.

Also, they are often very scared/skittish about thigs, especially other dogs.

Take your time deciding on this!
