He's always been on the itchy side of life, but he had eye surgery two weeks ago and when he got his cone off yesterday he apparently decided to make up for the lost two weeks of itching and chewed a hole in his leg/belly. He did quite a bit of damage before we realized what he was doing, and now he has the cone back on. The vet recommended the oatmeal bath, followed by using benedryl spray to see if it's an allergy issue and neosporen for the open sores. I like the Avon idea, though, as a more long term solution.
