Bear has developed what appears to be an allergy. His skin has always been redder than his brother's and he feels warmer than Zak, too. He's a bit OCD and likes to lick/chew so has had a buster collar on recently if unsupervised. I've removed all cereal from his diet. This has helped, as has the evening primrose oil. He's raw fed, nothing new in his diet. What else can I do? Elimination diet to see if he's allergic to his food? I feed a lot of chicken, hope it's not that!
