To me it is better than yesterday. The yellow patches seem to be going away and those we thought meant infection. We will be keeping up with the peroxide and cleaning it as well as keeping him on his proper food. I am also going to look around for the others things suggested by LadySam and Shazzy.

Good luck! Having a hairless dog I had a helluva time with skin issues until I found out what worked for him, now his skin is perfect. It's just trial and error :)

As with all critters when it comes to allergies, none of it is cureable. We treat the symptoms as much as we can.

The food change would be too sudden for a reaction to it for allergies... I'm sure it can happen, but I doubt it'd be a skin rash. It typically takes 6-8 weeks before the body reacts to something internally for a bad reaction. But he could be special and have a reaction that fast, but not typical.

Lucky he has been on the non fish food for awhile. We were blaming the bumps on pimples ( I know stupid of me not to check it out). When we noticed them looking infected is when I started looking on the net. I found pics and thought mange so hubby called vet. By what we described they said get him back on his food and clean it with peroxide. He is improving at least I think it is. We are keeping an eye on it and if I don't keep seeing improvement it will be off to the vet for treatment.
I will not be changing food again unless told to by a professional. I have learned my lesson at his expense. Thank you though for your information. I will file that away food allergies take time to develop into a rash. I will get this one day and be a good owner I promise you guys.
