  • Big bites for our big dog

    By on

    He's not pooping quite as much with this brand of food (still a lot) but that's not necessarily a bad thing. The bites are a little bigger than other brands, but that keeps our bunny from eating them. Our dog really likes the food and it seems like it's keeping the old guy feeling good!

  • Enthusiasm Quashed

    By on

    I purchased this food for my dog since I wanted to give Taz higher quality food. A friend had given us a bag and Taz loved it. Since getting this bag Taz has slowly shown more and more a change in his enthusiasm for mealtime. We even tried toppers to which helped a little. His most recent dish he pushed away with his nose. He has never done that ever before. He isn't a picky eater. Maybe it is just Taz, maybe not. Now I have to find something else.

  • Really keeps him young

    By on

    When my pup was around 7, I switched him to the senior hills dog food. He was slow to get out of bed and stiff. Switched back to this and he was right back to normal, alert and active. Was surprised to see such a difference is food from the same maker. Flash forward 3 yrs, he is now 10 and missing a leg due to cancer. He is still super active, plays Frisbee twice a day every day, very playful and energetic. Love this food.

  • Big bag for the Yukon!

    By on

    My 9 year old Husky Sam mix has reached that age that he needs some supplement help with his joints. In addition to this food he is also getting a joint supplement pill once per day. I love getting this on auto ship so I don't have to carry this into my house from my car! This is our first bag so we'll see how it goes on the joints!!

  • Fussy Greyhound

    By on

    I have tried about three or four different kinds of Hills Science Diet dog food for my greyt and she eventually snubs her nose at each. With this one she has seemed more engaged and doesn't just stop eating because she doesn't like it. So far, so good. Prefer Science Diet and this flavor, at this time, seems to have rung her appetite bell. Thank the stars.

  • My Dogs Love it!

    By on

    My Shiloh Shepherds have been on two other foods for years, dealing with stools that were not good,ie mushy.. but we thought it was top of the line and afraid to try anything else.. Switched to Science Diet and their poops are now normal colored and formed and well... normal... even after 1 week of starting on it, and they have gained weight at last. Best stuff I have ever bought. And they love the taste.

  • Does not like taste

    By on

    After ten years I have FINALLY found something my lab won't eat. This food. I was disappointed because I was trying to find a cheaper version of the Royal Caine prescription food. Cannot attest to how it works because I have to mix it with another food.

  • Not the one

    By on

    Food was delivered quickly. Unfortunately, our 55 pound dog would not eat it, possibly because the chunks are on the large size. Note that our dog is a fussy eater. Was hoping that this food was the one.
