I feed all 3 of mine Nutro Ultra Weight Management. The kibble is smaller than other brands I have used, which is great for Maggie, she's only 7 pounds. Grant pretty much inhales his food, no matter what it is. I feed the Weight Management more for Sadie, she's a little chubby. I can't really buy 3 different foods for each dog due to the expense of it. They all really like this brand though.
