Glad to hear Raggs is doing good with his diet. I hope you didn't think I was criticizing you at all - certainly not. Just wanted to pass that on because I figured I was helping giving Shadow the livers but the vet said probably not so much. But if it's working for Raggs that's absolutely all that matters.
Could you just wash his tummy if that's all that's dirty? I agree giving him a full bath or sending him to the groomers would be too much for him.
Hugs to you both. Be strong Raggs, your mommy loves you!
