Has anyone ever had their frenchie on a hydrolyzed protein vet prescribed? Im thinking of giving it a shot to try an pinpoint any food allergies since my little guy seems to suck on his leg a lot. The weird part is he only does it at night. Any recommendations on brands? I currently have him on Fromm adult salmon but, wanted to give the hydrolyzed a try. I also heard it would help with tear stains. I've been having trouble with that as well. We wipe his eyes sometimes three times a day. We use a medicated wipe, than a dry wipe, and than add coconut oil.
