Hound dog mom I would like to know your opinion on this: I have my yorkie on hk zeal, merrick canned,werva canned and natures variety instinct. He will eat the zeal but he loves loves the canned foods. The reason I give him the zeal is because I thought it was the better choice. Would it be better to continue this way or could I just rotate with the canned foods. I want what is healthier. Thanks
