The mother had 4 blue puppies and 2 black. The 4 blue puppies started losing hair on their ears and back around 6 weeks. They were treated with a bacterial/fungus shampoo and the hair seems to be growing back. I spoke with the vet today and the strange thing is it was only the blue puppies that were affected with this. She said she did not believe it was an auto immune disorder and the scraping showed no mites. She also said she did not think it was color dilution alopecia, which isn’t usually seen in gsd dogs. She did say that the bacterial infection could come back and she also said the bacterial infection could be genetic, and I have never heard of this. Does this mean these blue puppies are inferior in some way? I have an older blue gsd and she is very strong, healthy and beautiful. Should I run from this puppy?
