I had my dogs on the innova small bites and after a week or so being on it, Tucker would throw up every single morning, I thought it was because he had an empty tummy and needed to eat??? Maybe it was the food???  Their poop was ok, they didnt care much for the food so i swtiched to something else. I have read the ingrediants of arcana and they do look awesome. They didnt have it any where in my area so I looked into something else. Good luck with your food search!!
