We have our first hot spot and it's nasty. I'm taking Harry into the vet's office tomorrow but until then he's miserable and he stinks! It's obviously infected and I had no idea until 2 days ago that something was even wrong. I thought it was his ears (the smell) but today when I bathed him I noticed an oozing from the back of his head. I read some things online to do before I take him in tomorrow so I've shaved the area and put cold water and hydrogen peroxide on it. I have no idea what could have caused the hot spot in the first place. I have him on Blue Buffalo and honestly he's never had any skin problems until I put him on this food. He's been licking more and he now has this hot spot. Before the Blue he was on ProPlan the shredded chicken formula and we never had problems. He was on that for months. Could be he was bitten by something outside or he might be allergic to grass. It's so hard to tell. Advice is appreciated and I will update when we know more.
