How many cups come in the 21 pound bag?

I can’t say enough good things about this senior dog food. My older dog had been struggling with stiffness and mobility, and within a few weeks of switching to this food, I noticed a real difference. She’s moving more comfortably, getting up easier, and even has more energy on our walks. It’s such a relief to see her feeling better again. I truly believe this food has helped support her joints and overall quality of life. Highly recommend for anyone with a senior pup who needs a little extra support!

I started using this food a few dogs ago and continue to use it as my dogs age. I noticed immediate results in the cognitive state of my seniors, as well as super soft fur. And good poop pickups too. Seriously, it made fast and noticable improvements!

I have three Boston Terriers, who are known for their energy and spunky personalities. Recently I had noticed my oldest Boston, an 11 year old female, starting to slow down a little and not have her sudden bursts of energy like she’s always had. I started researching food for seniors and landed on this one from Hills. My girl has gone from lethargic to full-on crazy dog!!! Her spunk is back and she acts like a puppy 24/7! I love it! My other two also love the food and I have one who is an incredibly picky eater.

Made my dog sick

Changed him from another Hill’s product to senior and he did okay initially but then a new bag came and the food looked a bit burned - a few days later he was sick

Changed him from another Hill’s product to senior and he did okay initially but then a new bag came and the food looked a bit burned - a few days later he was sick - vet ran tests and determined something was off with the food. We will not be buying it again.

I ran out of the pups food and completely forgot to order some. I ordered last night and my whole shipment arrived before 1pm. Such fast and amazing service.

Madison doesn’t like the taste and since we started this good, she fights with me to eat. I love Hills because the food is very good and healthy but I still need her to eat. I’m not sure what to do. I have added food toppers and other tasty bits but she licks out the good stuff.

Great Product!

This food was recommended to my dog by our vet and he has loved it just as much as the previous hill science food he was on. We have also seen a huge difference

This food was recommended to my dog by our vet and he has loved it just as much as the previous hill science food he was on. We have also seen a huge difference in his weight over the 6 months he’s been on it. It has also been great to buy this product from Chewy as they ship it right to our door every month and we never risk running out!

Wide selection and very prompt delivery!

We live in a rural area several miles from a small town. I had my order in two days. Amazing! And my dog loves his new food.

This has nothing to do with chewy..

She will not eat it. She scurries past it like it’s trying to get her. She’s a German Shepherd.
