Any thoughts on this brand? Watched a 30 minute video and came away with more questions than answers. Our Yorkie has high liver numbers. She has been on Hill’s ID because of digestive problems. For the most part these problems disappeared when taken off of Hill’s ZD and put on the ID. She is the product of a puppy mill. She is 9 yrs old now and want to keep her in good health. I was appalled when I started researching dog food in general. She deserves the best after such an ugly start.
