Most people have told me their dogs loved it, but didn't benefit at all. Gained weight, horrible breath, etc with what goes with low-grade foods. I have never fed it...the repeated tellings of weight gain immediately turned me off, as with any food for my dogs.
We have had a lot of luck with Canidae you can buy it at Blue Seal Feeds. It runs about 37.00 for 40 lbs. My dogs love it and eat less then if I bought a cheap food. They also make Filadae for cats. You might look in to something like that. Here is a link so you can read the ingredients. Let me know what you think. http://www.canidae.com/dogs/all_life_stages/dry.html
