My 10 year old JRT had terrible skin allergies....bald spots, constant biting and licking. I started making my own food for her while using nuvet powder. It's been 6 months now and she's never looked better. I was able to take her off the steroid she was on, she's lost weight and she's happier. I'm sure it was combination of cooking her food, added vegetables and the nuvet. I've been very happy with it. And, it's important to use a supplement if you're making your own food. I needed to change the code I use for the product. Sent an email. It was done in a couple of hours.
