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.

Quality food and Chewy Service for the win!

Chewy is by far the most dependable service for pet food. Fast, friendly updates and discount options for recurring shipments. They offer the most complete line of pet foods so I never have to wonder if I am going to the store only to find an empty spot on the shelf for my preferred pet food. I just don't go to the store for pet food anymore. Never disappointed by Chewy! This food has agreed with my daughter's Great Dane and has kept her strong and healthy.

would not recommend

I have fed this food to my dog for a while now… and at first the food was great, my vet even said they recommend this food, but then my dog would get sick for a week every time I got a new bag of this food. I’m not sure if that is a purina problem or a chewy problem, but I will be looking for a new dog food!

Good for the pickiest kibble rejecters

My 2 year old Bernedoodle loves this! It's been very hard trying to find a kibble that he won't reject and also agrees with his stomach, he's been ignoring his food until he's extremely famished and usually has to be coaxed to eat with some kind of treat mixed into it. Decided to try this since it has soft meaty bits in it, and he loves it so much he's been eating bowls of his old food as soon as some of this new food is put on top. He eats the soft bits first but is happy to keep going and finish the rest. Fingers crossed that he'll continue being enthused about it!

Ol’ fella loves this!

This food is so good for the dog! I like that it has extra nutrients for his health. Plus, he likes it! He’s been known to spit out bits he doesn’t like or eat around them! Clean bowl every time with this!

Crumbly and powdery!

I've been buying Purina one for my dogs for a while now and just ordered this off chewy for convenience and wow it is very crumbly/ powdery plus my one dog has been vomiting ever since the opening of the bag. I might have to make a switch if this is the new quality!

Purina One Large Breed

Our 8 y/o golden does very well on this food and loves it when breakfast and dinner time comes. We are switching our soon to be one y/o golden over to this formula from Purina One Large Breed Puppy. The formula is balanced and complete and Purina is local to us. We support Purina and are happy it meets WSAVA and AAFCO Guidelines and is backed by years of research.

Good food, great service

My dogs went crazy over this food, from first bite, I'm happy because they hadn't been eating well for several weeks. Having a huge bag delivered to my door, promptly, was great!

Purina ONE

Been feeding for 3 years to our rescued German Shepards the look great and love to play. I trust Purina more than any other company as I've been to the research farm and seen how they test all the ingredients in all their feeds.
