I lost my corgi to Degenerative Myelopathy on August 6, 2009. His name was Ricco and the best gift I have ever received! I miss him terribly! I stumbled across this web site while I was looking for a reputable breeder that tests for DM. Wish I had found it sooner! I realize there is no fool proof test for the disease, but after experiencing it first hand trust me if there is a test that "possibly" may help to not go through this again.... All of the breeders I have contacted know NOTHING about the disease. If you can believe that. They wind up asking me questions about it. Which I find very odd! So, if anyone knows of a breeder, has some info or if you are a breeder I would greatly appreciate any help! I am in Southern California. Thanks....:)
