Hello! I've got a 10 year old chorkie, and he is constantly scratching. He's been to the vets twice already, the first time he was flead, wormed and had his anal glands checked, but he was still scratching after a week. The second time he was given some antihistamines, he's been on these a few days but he's still just as bad. I started giving him salmon oil mid October but I've stopped this incase over 2 weeks ago, incase he was allergic. The vets have said the next step would be steriods which I would like to avoid if possible. Is there anything I'm missing that could be irritating him? (Nothing had changed in terms of cleaning products used in the house etc) Any advice would be hugely appreciated!
