I used to feed Graysee the Innova brand, and I thought she liked it because the kibbles were small. But, she tired of it after less than a year, and I switched to the Blue Buffalo, which has larger kibbles. I thought she wouldn't like the larger size, but I've come to realize that as long as she can fit the food into her mouth, she'll eat it! She was a little bit of a fussy eater as a puppy, but now that she's four she's a great eater!
