A deaf dog - any help out there?

I have just given a home to a 12 year old dog who is deaf. Has anyone any tips on looking after her.? I mean because of her deafness - I am a long time dog owner. At the moment she is kept on a lead for walks
Answers:
Not sure what you mean by looking after her. If you mean how to communicate, have you tried hand signals? Her previous owner may have trained her with this, you may need to play around with this and see if she recognises any. You may do some research on this as well.
You also may need to retain her in this. Example: Two pounds on the floor (she can feel the vibes) means "outside". As so as you do the two pounds, take her straight out side. Soon she'll put the two together for the meaning.
As far as keeping her on a lead for walks, sounds wise, for her safety. Happy decovering!
