Good afternoon, I am new to the forum. I have a 55 pound pure bed female dogo argentino. I feed her Orijen large breed puppy with wild calling wet food. She has a rash on her back and I have tried pretty much everything to help. She does not scratch it but it is very unsightly due to the coat. Anyone experience this and have any ideas? I think it may be from the grass but I don't know what I can do to cure that. Shes a dog I cant keep her out of the grass lol Thanks in advance!
