Changed the recipe

My dogs used to enjoy eating this and now it sits in their bowls all day. I have a dog that eats using a slow feeder because she inhales her food, but will not eat this anymore. Either my dogs are tired of it, or the company has changed the recipe. Either way, I have 3/4 remaining of a 40 pound bag that my dogs won’t eat. Very disappointed.

I'm bigger than I look!

My name is Chloe and I am a Teddy Bear who will be 13 on the 13th of September. I have always been on the Science Diet and even though I'm little, I prefer the LARGE BREED kibble. As I got older, (after five) we wondered about the more dainty pieces and I ate it, but I wasn't happy, so one bag later, my Mom got the big pieces again and the rest is history! I like to play with the big dogs, too, or any size, for that matter, but I guess in my mind I'm a Big Dog Now. I'm glad she signed up with Chewy, too, so I won't ever run out and have to munch on tidbits! The people who helped Mom are super nice, too, so I can say I really like this new "restaurant in the mail!" What's not to like, right?

something wrong

My dog has been eating Hill's for awhile now with no problems at all, but recently I purchased a bag of your dog food and I have been breaking it down to that when I add this dog food my dog throws up all the food. When I leave Hill's out then my dog is fine.

Ozzy’s feast

My Ozzy loves this food. Since we switched from a more expensive another name brand to this, there’s nothing left in his bowl and he looks forward to each meal!

Great food!

We've tried lots of different brands of dog food but have been using Hill's for the last year and plan to continue. It has great nutritional content and our dog is healthy, regular, and has lots of energy and, most importantly, he loves it!

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

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.

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.
