I've worked and fed dogs on nothing but RF-1, Super Fuel, Peak Performance 2, etc over the years. I can tell you it never made any dog I worked on it, or the others, run hot at any point, and they were fed absolutely nothing BUT that along with water and some fiber to help form a stool.

While it takes quite a bit to feed a dog nothing but the powder, it can be done as a meal replacement. Garner's Ch.Dexter was worked on nothing but RF-1 for his 1st show. Can-Am Boys Ch. Becky ROM was worked on Peak Performance 2, not to mention another champion dog I had, along with other winners, fed nothing but Super Fuel at the time just to see if it compared favorably to the rest.

If feeding a raw diet, you don't really need any supplements, at least nothing like RF-1, etc, as a balanced raw diet, much like ours, is one that is balanced over time not every day.
