For those of you who have switched to a raw diet, how long did the detox stage last. I have had Hank on an all raw diet for about 3 weeks now. The itching is terrible and he has had hives, (mainly on his back) they are small hives but large enough to see through the hair. Other than that, his appetite is great and so is his energy level. No loose stool or throwing up. I feel so bad for him, I want to take him to the vet just to get some relief, but my wife wants to wait it out saying it is just detox. So what do you guys think?
