Thank God Lucas is doing a lot better now! I think it was the antibiotic that was giving him stomach aches or something, the vet told me to give him one every 24 hours isntead of 2 and that helped.
His rash is a little better, not great, but a little better.
Deep inside I'm convinced Lucas is not allergic to food, he has what the first vet told us two years ago, he has an autoinmune diseas, skin Lupus (discoid Lupus). Our second vet couldn't explain the high fevers that accompany the rash and he doesn't have fleas or mange or any skin parasites.
Now that he is on 10mg of Prednisolone, he is doing better. I will be lowering the dose in a couple of weeks, once he gets better.
I will still continue giving him the hypoallergenic diet for now just in case, because I can't risk changing his diet now. But once he is stable, I will change his diet to natural balance or Blue buffalo grain free and canned food.
He lost 3 lbs through this ordeal, he was 11 lbs and now8 lbs and I can tell because his face looks so skinny, my poor boy

Thank you all for the vibes they have helped us a lot

HUGs, Tammy
