I was so thrilled when I finally found a quality food that my two Shih Tzus would eat! But have they changed the formula recently? They still really enjoy the food itself, but every one of those little LifeSource vitamin bits are now carefully picked out and spit onto the floor. They definitely don't like the taste of them. I don't remember those being there when I first started buying Blue Buffalo. Other than that, it's great food that my vet recommends. I mix together the regular adult formula with the light formula to cut the calories a bit.
