Our 6 yr old JRT periodically has a very itchy bottom and presents his back end for us to rub, scratch. His anal glands have been emptied, so that's not it. The vet said it was an allergy and prescribed Apoquel which does help, but we are wondering if his diet is the problem. He is fed mainly on boiled chicken mixed with mashed mixed veg and rice. He had collitis and this food keeps him settled. His poop is normal. He sometimes has a raw bone. He also sometimes has chicken and raw hide chews, Baker's moist meaty chunks, pouches of Pedigree Vital in gravy. I'd like to hear from anyone with experience of this problems or solutions to suggest. He is a bright energetic typical Jack. This is he.
