I'm wondering if there is anything at all to help this? I'm thinking no, but can anyone whose dog has CDA offer any suggestions? Roo is a blue and she has CDA and lately it seems to be getting worse/thinner on her back/spine area. She has virtually no hair on her head from it and no hair on her belly/neck area at all. I do give her nupro, (it's been about a month now) but it hasn't made any difference, it actually seems worse lately. Any suggestions? I'm wondering about the missing link, but not sure if it would help.
