I have a Terv, he's about 3 years old now and has has stomach problems for a year and a half. The walls of his bowels are a little thicker than normal. I started feeding him the NV venison raw, but found that he liked the venison dry better (good for me, much cheaper!!) This is the only food I have found that does not upset his tummy. I LOVE this breed!! Riley is my second Terv baby :) One question: it is incredibly hard for him to gain weight, he's very skinny!! Do you have any recommendations on how I can put weight on him without tummy upset? He is REALLY not food motivated and will not eat at all sometimes, no matter what! Thanks!!!
