Questions & Answers

20 Customer Questions

Approximately how many cups of food will the 40 lb bag provide?
Answer by ChewyMay 15, 2018
There are approximately 66 cups of kibble in the 16.5 pound bag, 124 cups in the 31.1 pound bag, and 160 cups in the 40 pound bag,

Are the food pieces bigger in the large breed brand?
Answer by ChewyMar 17, 2018
The Large Breed specific foods will have larger kibble than the average size.

is this food good for 9 month labs?
Answer by ChewyFeb 05, 2019
This formula is specially formulated for large breed adult dogs. We'd suggest the Purina ONE SmartBlend Large Breed Puppy Formula Dry Dog Food for puppies.

Where is this food made and where are the ingredients sourced from?
Answer by ChewyJan 11, 2019
A majority of ingredients used in Purina products are made in the US and are sourced in the US. Like other food companies, they do source a limited amount of ingredients from other countries. These ingredients are primarily essential nutrients, like taurine or vitamin B that are not commonly available in the US in the quantities needed.

Loves his food!

We've been Chewy customers for a long time. Lately I've noticed a "Johnny Come Lately" brand named Hollywood Feeds trying to build their business by comparing themselves against Chewy, and I'll not have it!!! Chewy IS THE BEST in every way! Mack loves his food and he never runs out because Chewy stays on top of their game in offering tremendous variety, super fast delivery and fair prices. Why mess with a very good thing?

Not Chewy’s Fault

We have been buying this dog food for sometime now and it has gradually getting worse in quality. This last bag we got was mostly crumbs like you see at the bottom of the bag but it was ALL in the bag. I would still recommend Chewy as this isn’t their fault. They are just the broker per say. It is all the food company that failed.

Golden Retriever loves it

The puppy version of this food was recommended by our vet & when she turned one, we switched our Golden Retriever to this adult version & she loves it. After her spay surgery, she lost her appetite so we used the canned version of this, mixed with the dry & that helped her start eating again.

I have fed this for several years to my adult dogs and never any issues . They never get tired of it .I use the puppy version when girls are pregnant and have puppies. Again never any issues. I have Goldendoodles,Poodles and GSP'S.

Only Purina in our house!

Purina one is a wonderful food, or vet recommended years ago and we’ve stayed with it ever since. Dog loves it and healthy coat just proves the point

Great food with great ingredients.

I was looking for a brand of food for my dogs (husky mix and poodle mix) that was both cost effective and had great ingredients. This was definitely the right choice! My dogs love it, I could tell right away that it's working well for them, and there aren't a lot of filler ingredients.

Great transition

We moved from the large breed puppy to this large breed as our Rottie just turned two. He loves it, did great with the transition and he isn't as gassy!

Our picky eater loves it!

She picks out the little chicken morsels first, but still finishes the rest. We tried so many expensive foods before switching to this, and we had to mix in canned or human food to get her to eat. The only issue with this food is our pup is becoming a bit of a princess since everyone tells her how beautiful she is and complements her shiny coat.

Best for Large Dogs

I have been using Purina ONE Natural Large Breed +Plus dog food for many years. I own three Great Pyrenees/Anatolian guard dogs for my cattle. They love it. I buy 2 bags at a time as they go through one bag real fast. When I open my second bag I ask for my autoship.
