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.

Angel Loves It

My wife was traumatized by the experience of trying to get our (now deceased) Merlin to eat the prescribed diet food. So she was not happy when we learned Angel needed a vet diet. We bought some Royal Canin to try with her, but my wife did some research before thinking about opening it. She found this food and decided to give it a try. Angel loves it and eats it enthusiastically. The pieces are a little large if you have a small breed dog, but they aren't the largest pieces of dog food we've ever seen. My wife is happy about this food's ingredients and it apparently smells and tastes good to Angel. We're already seeing changes from the new food and just ended her transition yesterday. No problems at all with the transition, other than Angel once refusing to finish her breakfast after she ate all the Blue Buffalo pieces and only had her old food left in the bowl.

Dublin loves the taste!

After his kidney disease diagnosis we started him on Hills KD. Finished a 7.5 lb. Test bag - seemed OK so we bought the 27.5 lb. and after 3 meals he rejected it

After his kidney disease diagnosis we started him on Hills KD. Finished a 7.5 lb. Test bag - seemed OK so we bought the 27.5 lb. and after 3 meals he rejected it completely. Like, would not touch it. Had a Rx for Blue Buffalo KS called in, and he LOVES it. Wags his tail while eating again. PLUS chewy refunded $144 for food he couldn’t tolerate! Life is better, & Dublin is bright eyed & energetic again. THANK YOU!

Blue Buffalo brand

Katie already ate Blue Buffalo. I read reviews that dogs did ate all of it. The smell is like there is no weird preservatives. It is a light and delicious smell

Katie already ate Blue Buffalo. I read reviews that dogs did ate all of it. The smell is like there is no weird preservatives. It is a light and delicious smell. Renal support food is expensive. It is nice to physically smell the quality difference.

She LOVES it!

Our 15 yr old girl Storm was recently diagnosed with kidney problems and we have had to switch all her food to a kidney care diet. She would not eat any of the Science Diet KD kibble, or their chicken canned food. The 1st ingredient in the Blue Buffalo kidney care kibble is de-boned chicken so I thought we’d give it a try. As soon as it arrived Storm started sniffing the bag, then when I opened it she started jumping up and down! She loves this food and has started to regain the weight that she had lost and I have even ordered her the Blue Buffalo canned kidney care food to add to the kibble. Along with the meds that her Vet prescribed and the Blue Buffalo kidney care food Storm has bounced back to her happy energetic self!

This science diet does not contain what other science diet brands. No corn or by products. Our four legged kid went from looking miserable, soft stool, and no appetite to her old self. So we manage her CKD as well as we can wo adding more issues. We will keep buying this brand, and being appreciative a company values our dogs health because ingredients matter!

Quality ingredients

I chose this food for the good-quality ingredients which are far superior than the other prescription brands for kidney support. I rate this 5 stars for that. But

I chose this food for the good-quality ingredients which are far superior than the other prescription brands for kidney support. I rate this 5 stars for that. But there are two things I wish could be changed - the little dark pellets settle to the bottom of the bag, and the size of the kibble could be a bit smaller since they're so hard.

Finally one she likes

Recently diagnosed with renal disease and vet Rxed the Hill's renal kibble. Mollie hated it but worse yet were the doggie sized cow pies that she produced. Vet then

Recently diagnosed with renal disease and vet Rxed the Hill's renal kibble. Mollie hated it but worse yet were the doggie sized cow pies that she produced. Vet then Rxed Royal Canin which again MollDog didn't care for but at least better formed doors. Finally tried this and she eats it well enough and stool looks like doggie doors should. Note that we carefully transitioned all these pricey diets over at least 10 days. Perhaps save yourself most of $100 and start with this brand.

A maybe for picky pups

My dog's symptoms have improved since she was diagnosed with kidney disease (stage 1 I believe, she wasn't very far along) and started this food. I chose this food

My dog's symptoms have improved since she was diagnosed with kidney disease (stage 1 I believe, she wasn't very far along) and started this food. I chose this food because of the ingredients (no fillers.) My dog is picky when it comes to food. She eats the larger pieces of kibble but spits out the smaller pieces. The other dogs in her life, who are less picky, don't mind the smaller pieces and eat everything. I'm honestly not sure if the smaller pieces are imperative to a complete diet but if your dog is a picky eater might not be the best food.

Chewy is so awesome

I'm not leaving a review here for the food. Because, of course, it's amazing. It's a prescription diet for my dogs bad kidneys, but chewy themselves is my review..

I'm not leaving a review here for the food. Because, of course, it's amazing. It's a prescription diet for my dogs bad kidneys, but chewy themselves is my review... they are sending me a replacement immediately when the bag I received had to slices in it on the side from somebody opening up a large case with many bags in it, i assume, Obviously from a box cutter or something and was unnoticed by the shipper... That being said, I informed chewy immediately upon delivery about the problem and they immediately are sending me a replacement... What can I say about how awesome they are.. I know that accidents happen but this is above and beyond. Thank you Chewy so much
