Questions & Answers

23 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.

He LIKES it!

My dog has never eaten well. He has never been enthusiastic about food and generally had to be coaxed to eat. All that changed with this food. I cannot say if the appetite will continue but he eats all of his food and reminds me if I am late feeding him. It is good to see him eating normally.

My Dogs LOVE this food

After having a doberman with chronic pancreatitis who thrived on Hill's Rx I/D for years, reaching the age of 16, I was sold on Science Diet. But 1) they seemed to have changed their formula and the dogs didn't care much for it any more, and 2) they got way too expensive. SO I started looking for an affordable alternative. Purina, like Hills, has well educated people doing research into animal nutrition and they have a good history. My dogs have been eating this formula for a couple of months now and I can't tell any difference in weight, amount of stool output, or coat quality. It's a winner

Last 2 bags have lots of crushed (like meal) food instead of kibble/bites. Ends up in bowl like mush instead of chewy bites of food. LOTS OF CRUSHED FOOD PER BAG. We have used Purina for all of our dogs over the years and have never seen anything like this.

Dry dog food

Ordered this inadvertently but our dogs like it. So until are next auto ship ( which is Chicken & rice ) they have no problem with it. Food came promptly and was delivered with no damage.

My dogs love this food

Both of my dogs absolutely love this food. I put it in each of their bowls and they gobble it right up. They sometimes can be picky eaters and has turned their nose up at a couple of different more expensive brands. But I have also noticed that both of my dogs coats are a lot shinier and they seem to have more energy. I highly recommend this product for dog owners.

great option for big dogs!

My dogs seem to really like this food. I like the ingredients list. And it has some joint supplements in it.

Just okay

Our dog is a blue tick/ great Perineese mix named Pepper. Her food wasn’t meeting her needs and she was losing weight, so I ordered this to try to see if it would help her put more weight on. She eats it, but doesn’t “devour” it like I thought she would.

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.
