There are three Yahoo groups:
DeafDogs: http://groups.yahoo.com/group/deafdogs/
Texas DeafDogs: http://groups.yahoo.com/group/TexasDeafDogs/
Deaf and Blind Dogs: http://groups.yahoo.com/group/blind-deaf-dogs/
And a Web site: http://www.deafdogs.org/
The Web site has a lot of information, lists adoptable dogs, and points to resources like vibrating collar makers.
Deaf Dog Atlas is a resource where you click on the maps till you get to a locale you want and read profiles of deaf dogs and the people who love them. See how well and happy these dogs are with their families. If you have a deaf dog, why don’t you add your dog to the map?
