I have four dogs which one of them has horrible skin allergies. After months of medication, I put them on Canidae Platinum and his allergies got much better. I ran out and put them on regular food and unfortunately his allergies came back. Now he is back on Canidae and his allergies are clearing up again. All of my dogs, including my older dogs seem so much healthier on it. I always get compliments on their coats. It seems alot more expensive but one bag of Canidae lasts twice as long because you dont have to feed as much because it does not have all the fillers. I HIGHLY RECOMMEND THIS FOOD!!!
