My husband bought Dinovite for our Jack Russell, for her itchiness. After a month of feeding her the dinovite, there was no change, she was still itchy. (She has never lost hair, chewed or licked hair off, just had a bad case of “scratch my butt”). I have since switched to plain old fish oil, I open a capsule, pour it on her food (Blue Buffalo) and so far, no issues (3months+). And as far as ingredients, you should look pretty closely to some of them, some are big animal livestock supplements, one of them is commonly used as a cat litter filler and there is at least one of them that can be toxic if used long term. Yes, I looked up the ingredients, and while most are good things for our pets, some are certainly questionable.
