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

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.

Hill's special dog food

This dog food was on backorder at my vets place. Chewy was the only place I could find it. The price was very reasonable and they shipped it fairly quickly.

Would continue!

My 1.5 years old Lab Cattle dog mix has food sensitivity/IBD. This is the only food that's been working for him so far. He definitely is doing much better in terms of stomach, skin and healthy weight. He has put on muscles. No diarrhea episode has occurred since we switched to this food. He's a picky eater, so nice to have multiple flavor options in this category. I also love the fact that they add Taurine in the food since there was some investigation couple of years back regarding lack of taurine in grain free food and DCM in dogs. I surely trust Hill's as a brand and definitely they were not in that list of 16 brands. The only thing that's a little downside on this would be the cost, but since I'm getting the quality and results for this cost and it made my pup feel better - I guess I made my peace with that. Also, Venison is not available in market for some reason and Duck flavor is not available to buy on stores, I haven't found a wet food anywhere. So I'd love to see more availability on these 3 variety for d/d and the canned food.

My Dog Loves It

We had our dog tested for allergies and this was one of the foods that he can eat without giving him digestive distress. Thankfully, my dog loves it and actually licks the bowl after he's done eating! It's a relief that Hills makes several different foods that is safe for my dog....thank you!!! This is a prescription diet but Chewy makes it so easy to process orders - even Auto Delivery!
