How many cups in the 25 lb bag?
Answer by ChewyJun 17, 2019
The 25-pound bag has approximately 100 cups of food.

I see the bag says “New Formula and kibble”. Can you tell what has changed? Is it possible to see the ingredient side of the bag? Thank you

Our vet recommended this for our diabetic baby but is this something our other fur baby can enjoy and have as well?

Not for our dog...

Tried two of three flavors and could not get my dog to eat without adding other food items. This most recent purchase of Potato and Duck did not sit well and he vomited two meals. Our only assignable cause was the introduction of this food.

Expensive but worth it

Well, it's never fun to find out that your dog has dietary sensitivities and needs a prescription food. But since that's what happened to my girl, I'm so glad we tried this food. Her tummy is happy again, and she seems to love the flavor. Her coat is beautiful and she's got lots of energy. Vet says if she does well on this, we might transition to a non-Rx food with the same protein later. For now, she's doing great and I'm so thankful for Chewy's simple & quick processing of the prescription info.

Refused to eat

My dog refused to touch this expensive kibble. Guess I’ll donate it to animal shelter.

Better Than the Last One

I’m giving this 4 stars due to my pup not having to poop every other hour. He’s able to sleep through the night and hold it until morning. He’s sketchy with the smell and possibly taste, but he will eat it eventually. We’re currently awaiting a new recommendation from the vet.

Great dog food!

I was scared that Dexter wasn't going to like his new food but he loves it! That makes me so excited! Hopefully he will start feeling better now.

Dog loves it

My dog has been having GI issues/food sensitivities and it's been difficult finding something he likes and that also agrees with his stomach, but this seems to do the trick. He gobbles it up and gained back some of the weight he lost. Will stick to this as long as it keeps working!

My pets are very fussy eaters and so far I have gotten them to eat this kibble a little bit at a time. I have 2 Cockapoos that are very difficult to feed.
