  • Picky pup approved

    By on

    I have only been feeding my dog this for about a week now son I haven't seen any improvement yet, but I am super happy that my really picky puppy eats this food right away! Normally she will let it sit in her bowl until she's starving, but this food is gone as soon as the bowl is on the floor!

  • Small vs. Petite kibble

    By on

    Per my vets recommendation, I only feed my dogs Science Diet. However, I thought I would change things up a bit since my chi is getting older and experiencing issues with her joints. I ordered "Small bites mobility" thinking the kibble size would be the smaller "petite" size. I was wrong, the kibble is larger than the petite kibble and since she doesn't have teeth she is unable to swallow the "small bite" kibble. Looks like she needs to stick with the petite kibble. Oh well, lesson learned. I gave it a 4 only b/c I would like to see more protein, veggies and nutritional content rather than fillers.

  • Another Good Dog Food

    By on

    I have one pickey eater so sometimes when I rotate foods, he won't eat the new food. However, he has consistently eaten this one. The kibble is a little larger than expected for small bites, but must taste too good to be an issue for my pups. I also like that it has glucosamine chondroitin for joint health.

  • good product

    By on

    ordered by mistake but the guys still eat it. Don't know if it helps their mobility. The Chihuahua/jackrussell mix(over12yrs) is still hyper or off.... The shizhu/pekenese is too cool to be hyper

  • Dog enjoys eating

    By on

    I acquired this kind of food from a friend whose small dog did not like this product. My picky eater medium size dog, however, LOVES this food. Whereas his other food would sit around all day, he eats this right away at feeding time. I don't stress about my dog not eating anymore!
