Help!!!!!! I am at a crossroads regarding my 13 year old Sheltie Jake. He developed skin issues about five years ago. He was on Pro Plan Turkey which seemed ok for his skin for most of his life. He was a Champion showdog for most of his life and had a gorgeous coat. While on this food though, he did develop crystals which I understand to be hereditary. He had surgery because he had bladder stones which were removed in 2004. Well after this he developed horrible scratching, blood was everwhere. He has since had allergy issues. He scratches throughout the year (we live in Wisconsin) but especially in spring and fall. We have been able to control scratching with benedryl, where there is no blood and hair actually grows back but I can still tell he is not content. The other day Jake had blood in his urine, took him to our vet, and of course he has developed crystals in his blood again. We are at a crossroads, do we put him on the diet to reduce crystals to have him scratching the hell out of himself, OR do we keep him on his fish and potato diet and give him a daily pill to break down those crystals? Please help, anyone who has had experience with this combination of issues before. I need someone who really understands my problem.
