Does purina one have affco stamp of approval
Answer by ChewyJun 01, 2021
Purina ONE Lamb & Rice Formula is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for maintenance of adult dogs.

Hey I've got a question, I ordered a 40lb bag. My dog only eats about 8oz a day so that would be around 11 weeks worth of food. My question is how long does the food keep once you open the bag?
Answer by ChewyOct 02, 2018
Pet kibble has a general shelf life of 1 to 3 months once open. We recommend placing your kibble in a plastic storage bin for prolonged freshness.

How many cups are in a 40lb bag?
Answer by ChewyJan 27, 2018
There's approximately 32 cups of food in the 8 pound bag, 66 cups of food in the 16.5 pound bag, 124.4 cups of food in the 31.1 pound bag, and 160 cups of food in the 40 pound bag.

Does the Lamb and Rice formula come in small bites?
Answer by ChewyMay 01, 2018
The Lamb & Rice Formula does not come in a small bites version.

Quality Dog Food

Been using this dog for for about 10 years now for a German Shepard and overall it has been a good quality dog food at reasonable price however the price keep going up and bag size got smaller over time and now it's about 25% higher than just a few years ago. Also the 40lb bag has been out of stock for over 4+ months and you were forced to buy the smaller size bags at a much higher price. This don't leave a good feeling and that is why I don't rate the product at 5 starts.

Love this!

My dogs loved this product, even more than the more expensive dog food. My vet recommended this and I see why. Even my picky dog, eats all her dog food and I didn't have to add wet dog food to it for her to eat it. Will definitely keep buying this product for my dogs.

110% recommend!!

I have a 1 year old Boxer who seems to be allergic to everything under the sun so we’ve had him on sensitive systems for a while but then it’s like he got bored with it(or just became super picky) and stopped eating it , so we tried this and it was the best decision I’ve ever made! He now excitedly waits to be fed and scarfs down every bite! Also for a dog with tons of allergies this food has kept his skin clear of break outs as well so I 110% recommend this !!!

Great Taste Healthy Living

After Fed Ex delivered a destroyed box Chewy replaced the damaged bag quickly and at no additional cost. My dog loves the flavor and has never been healthier. Chutzpah is a Belgian Malinois and very finicky with a great deal of energy. We feed him 1 cup dry and one can of matching wet, only after he finishes his Dry.

Never would have thought

Never in a million years did I think Purina One would be where we would end up. Purina Pro Plan didn’t work well for my GSD, so we went on a culinary adventure trying to find something I wanted her to eat that she also wanted to eat. Eukanuba was her favorite, but it became exceptionally hard to find. Her pickiness level hit 100 and went out on a whim hoping Purina One would work and it did!! She waits by her bowl now at dinner time waiting to eat. Her poops are perfect and also smaller than when when was on PPP. Hopefully this is our last stop on our culinary adventure.

Inexpensive and dog prefers it

I used to buy expensive dry dog foods but discovered this a year ago when my sister visited with her dog. My dog literally whined for it and stopped eating his other food. Now it’s all I buy, but I do top it in the evening with about a cup of meat/rice/vegetables that I prepare myself. Haven’t noticed a significant change in his coat, health, stool or energy levels. We are out on walks/hikes about two hours a day.

Faulty food

Normally, I have no complaints about the Purina food, but this time it had a very strange appearance. There are some unusually large chunks in this batch. Since I am on a strict budget, I cut the chunks into bite-size pieces/ God willing, it won't do any harm to my dogs.

Good for dog

Fed only this to our lab mix for the last 10 years after rescue. She is now almost 14 and still chases the tennis ball and walks a couple of miles.

Great for my older dogs

This was out of stock for a while and switch to another Prunina version, the dogs eat it, but when this was reintroduces the dogs eat the entire bowl versus munch.

Sadly the same happened with what I normally get and feed my German Shepherd. You was sold out. So I had to get something else or else my dog and cat would go hungry.
