  • She Loves it

    By on

    I was nervous about going from the puppy food to the adult food, no knowing if my dog would like it, and I didn't want to waste time or money. WOW - I cant keep her away from this new food! I now have to actually give her only the recommended daily amounts because I don't want her to gain weight. And I think I had hit a philological block when I didn't see my breed of dog on the bag. I laugh at myself now.

  • My Chi Loves It

    By on

    After many, many tried dog foods for my picky eater she does eat this one. I like that it has the very small bits and most of all the smell is not like other dog foods. I put this on auto refill so that says a lot for this one

  • Small Bites

    By on

    The food is the same, but I need to get in a larger bite size. Small bites is about the size of what a rabbit would leave in the yard. The food is the same, but I think she just swallows it. My bad!

  • Better Eating Habits

    By on

    My three dogs, all under 20 Lbs don't have a problem eating. I bought this bag to see if they'd like it, which they did however, the bits are really small and are like pellets, which doesn't give them the chewing enjoyment they were getting from their old brand, my fault and not the food's fault.

    We have five (yes,FIVE!)large dogs, several f them require weight management. This food has been a great value. Our dogs love it, especially the small bites, and they don't even ask to have wet food stirred in anymore.
