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.

Our latest shipment of dog food came with a new smaller kibble size. I preferred the old size, but this wasn't a big deal. I did notice that there were a lot more crumbs with this new bag/size and assumed that it was just because we dumped the bag into the food bucket and they were all at the top now. But we are halfway through the bad and there are still a tonne of crumbs as you can see in the photo. If this is normal we will be stopping our order.

Our dogs really like it however I will say we haven’t really seen any mobility improvement with our old dog due to the switch. I was buying locally but could only find smaller bags was glad to find it on here in the larger size which did make it cheaper per pound.

When I first introduced her to this food I was getting a smaller bag of a more expensive brand. I was going to switch her slowly but she had a different idea and was picking out the other food. I stopped mixing the foods and let her have the Purina One and haven't looked back. We have a staffy also and she loves it too

The dogs really loved this except one of them throws out the bigger soft chunks. They seem to be hard for him to chew. Like chewing gum is the image. I will be switching
