About BLUE Buffalo
Blue Buffalo began with unconditional love and some furry inspiration from a large breed Airedale, Blue. When Blue's family started a pet food company, their vision was clear. They wanted every pet parent to be able to feed their pet with the same care they would feed family. So they created the #1 natural pet specialty food to help furry family members live happy, healthy lives. Of course, they named it after Blue.

The ONLY Kidney Diet Food my 14 Year Old Dog Loves- Kidney Disease
By Savannah on Feb 14, 2021
I am so thankful for Blue Buffalo's kidney support diet. I truly believe it is a huge reason my dog is still alive today and thriving. My 14 year old cocker spaniel, Savannah, (almost 15) got diagnosed with kidney disease over a year ago. She pretty much stopped eating and I could not find any food that was good for her kidneys that she liked. I even tried cooking special food which did not work. I asked different specialty companies for some samples to try with her. Blue Buffalo was one of the only companies that sent some free samples and Savannah loved the food instantly. She literally scarfs this wet food down in the morning and shakes because she's so excited. I give her half of a wet can I am so thankful for Blue Buffalo's kidney support diet.

I give her half of a wet can Kidney diet in the morning and the Blue Buffalo dry kidney diet food at night but she liked this more. Sometimes I put fish oil in it too. It's pricey, but it's necessary if your pup has kidney problems. Other dog foods are way too high in phosphorus and protein. Now, Savannah is doing great as when she was a pup, sprinting around the yard with a huge smile every day. … more

Finally, A kidney support food my Shih Tzu will eat!
By WesJ on Feb 16, 2021
I tried all the other prescription kidney support foods before Blue Buffalo. My picky, picky Bridget, who is 16 years old, would not eat them. Then I found this canned food, and she gobbles it down!

This is my dog's current favorite
By happydogs on Feb 9, 2021
With kidney disease, my dog has become a very picky eater. She has gone through several kidney diet formulations, and this is currently her favorite. I don't know if it's the grain-free aspect, but it's nice to have a food that she enjoys eating.

Incredible!
By DA123 on Dec 1, 2020
Anyone with a dog on a kidney diet knows that it's not easy to get a dog to eat the prescription food! I found the Blue Buffalo dry food a few years ago, and it's the only food my dog will eat - and I tried them all. He recently had a tooth pulled, so I tried the wet food and he INHALED it. He liked it so much, we've added it to his morning routine permanently. He now wakes us up eager to eat. My dog has never been food driven - not even before his kidney diet. But he will literally stalk us around the house until we give him a can of this, so it must be good! Highly recommend for your pup who struggles with other kidney diet foods.

Mushy food - where's the substance?
By BlueKidneySupportFood on Oct 24, 2020
I was so excited to order the Blue Natural Veterinary Diet food for dogs who are experiencing kidney problems. I read the reviews and it seemed like it would be a good addition to the other kidney support food I give my dog from two well-known companies. I was disappointed when I opened the first can. (and I was forced to order a dozen cans.) It was all mush. My dog, Chance, still has teeth. He enjoys biting into things and chewing on meat. Chance has early kidney disease; he's not decrepid and toothless. Why can't Blue make some varieties here so that there is at least one variety where there are formed pieces of food for a dog to chew up and enjoy. Also, Chance was not wild about the I was so excited to order the Blue Natural Veterinary Diet food for dogs who are experiencing kidney problems.

Angel loves it
By StarrMarie on Dec 5, 2020
I have been using a different Kidney Support diet for several months and my toy poodle had stopped eating it. Wanted to try a different brand and chose this Blue Buffalo as it didn't have meat bi-products. Not a fan of the looks but Angel has eaten every bite of it each time she is fed.

Wonderful kidney food. Way to go Blue Buffalo!
By Momofseven on Sep 3, 2020
The other two canned dog foods for Kidney disease our two dogs would not go near. Had to throw them out! Waste of money. But when we found this one at chewy. After reading the ingredients I knew our dogs would eat it. They are not only eating it but chugging it down! Our little girl would not even go to her bowl of food in the morning. Now she stands there waiting for the food. All of us are so happy with this Blue Buffalo product. I would recommend it to all! If I could give it 10 stars I would in a heart beat.

Blue is her favorite
By Andy on Sep 8, 2020
I have switched to KS Blue canned and she eats it with ought any hesitation . The dry version she is a little less happy with but if I use both she does eat some of the dry KS .Her vet does not like Blue and insisted on not approving my order thru Chewy , had no real choice but to switch to a different animal hospital but that worked out ok. Our 14 year old girl has a lot of her personality back . That is a wonderful result .

Dog will not touch this stuff dry or wet.
By Princess on Oct 29, 2020
My Princess will not eat the wet or dry Blue dog food. The dry was so hard I even ground it up in coffee grinder. Was supposed to get refund or credit so far I do not see the refund or credit.
