My Cody just turned 3 on Monday. I feed him Buffalo Blue and boiled chicken which he's been good with for 2 years. About 2 months ago, I noticed that he was scratching a lot. I bathe him at the neighborhood dog wash monthly and he's never had a reaction to the shampoo. I know he doesn't have fleas, so I thought it may be due to the summer shedding. Today I took him to the dog wash and while I was blow drying him, I could see red blotchy spots all over his back under the thick fur. Could this be a simple heat rash? I can't think of anything that could cause this so suddenly. I feel bad for him, so I'll take him to the vet tomorrow, but still would like some feedback. Thanks!!!!
