We had tried fish oil in the past when trying to solve his regular itching problem (along with changing his food), but that didn't seem to make any difference. That was over a year ago, so I think I'll give it another try. Thanks for reminding me of that option

We are in the phoenix area, but I don't think it's fleas. He doesn't go outside beyond our balcony very much and we have another yorkie who isn't itching at all. If it were fleas, I would imagine the other one would have them by now too...
