What a Wonderful Convenience!

We were looking for a more economical way of feeding our two big dogs, who thrive on this food, and eat 70 pounds every three weeks. We found what we were looking for with Chewy, and find it very convenient to have the food delivered right to our door rather than having to drive across town for it and carry it from the vehicle into the house.

Riley Loves it so far.

I want my friend to have a long healthy life, I frequently check for problems or recalls, of the brand I was using, it had a few so i decided time to change, HSD doesnt stay in Rileys (a Gordon Setter) bowl for very long! 3 servings a day and she really loves it.. Time will tell about long term, she is 4 yrs old. It has only been 2 weeks, so she does have HSD in her system, Still full of pep firm stools she had no issues changing over Now if the price was a bit lower. Either way she has a new food

Great service!

I was changing from puppy to adult dog food & customer service was great & informative. Autoship is a great convenience and usually it arrives before the estimated date. Thank you for making our life and our beautiful golden retriever's life so much easier.

Great for bulldogs

Our old english bulldog has been eating Hills Science Diet for all four years of his life. For the first year or so we were switching back and forth between Hills and Taste of the Wild. Our boy loved both and didn't have an issue with either but ended up settling with Hills and he has ate it exclusively for over two years. Plus it was recommended by our vet. I do think it helps with his weight control as he's been able to maintain the same weight for the last two years. He is almost 90 lbs and eats 4 cups a day. He loves it, never has lose stools and has never had stomach issues or anything like that. We will keep rolling with Hills!

Pork Flavor

My dog did not like this food. I accidentally ordered it a second time and had to give away the second bag, because he would no longer eat it. He does not like pork and just I realized this has pork flavoring. I have a super picky dog, he also hates peas (no peas in this one), so I have to read the ingredients very carefully.

Arrived fast

Always ships super fast and a very reasonable price. We have a Rottweiler and French Bulldog and chewy is the easiest way for me to get kibble.
