I have fed mine BB and Wellness. Cozy and Lucy porked up on both very easily. Lucy never liked BB's lifebits- She would spit them out and feed them to Roxy. Roxy and Zoey (RIP) stayed lean.
All of mine are healthy weights right now. They all eat FROMM's Chicken a la Veg. 1/4 cup per yorkie and 2 cups for Buddy the Golden in the am with 1 tablespoon of Honest kitchen Force/ yorkie and 4 tablespoons for Buddy as a topper daily for breakfast. Dinner is fruit and veggies to fill them up but keep them thin
