When I fed more than one bag, I ended up with bad coats. Shreds are made of soy. Soy mimics estrogen in the body. Nothing I want in my boys. I will do it once in a while when its on super sale and the dogs do LOVE it, but I love my Captain Crunch cereal too...just know not to eat it. ;) I add toppers to my dogs' meals. A spoon of canned or some healthy fresh leftovers. I feed my pack in a row and no one strays from their bowl when they have a spoon of leftover pasta with sauce on their kibbles. Variety and healthy extras help them maintain good health IMHO
Becky we have fed our older dogs the shreaded since they came out with it. You have to feed more of it to maintain their weight but otherwise seems ok. The dogs we show and our stud dogs eat performance 30% protein. One of our old girls started to not want to eat and we switched her to performance. She loved it as do all the ones that are on it. Very palatable and puts great coat and weight on them.
