Shadow did amazing on the First Mate grain free but in light of recent events and information I opted for the grain friendly. The Acana was a failed attempt to find a more readily available food. She has always been an itchy dog, but it was out of control on the Acana plus her stools doubled in size, her coat looked like crap, her energy was down and I was struggling to maintain her weight. Perfect example of a good food that didn't work for a particular dog. With the DCM/grain free research I opted not to continue the grain free.[/QUOTE]
Seems like you are doing your research. Some say glucosamine is good but more studies show it has no affect.
I have a 7.5 year old GSD and he got real sick. Loosing his hair, dry skin, down 10 lbs and no energy. Had him on the best grain free i could find and yet he was dying before my eyes. I changed his diet, started cooking for him, gave him supplements, herbal formulas, and fermented cod live oil with little kibble. Less than a year later he is absolutely gorgeous , full of life and back to his perfect weight. So i know what a good diet can do. If i can help in anyway just ask!
