we are food lovers!!!

These 2 are so excited to eat this daily! They love the flavor and I love what it does for their skin and coats(we rotate with salmon as well), they’re prone to allergies from anything feathered so this was a game changer! We always buy this or salmon flavored in this brand!!!!! We have happy healthy babes!!!

I used to order the purina pro plan lamb and rice and unfortunately that product was discontinued by Chewy . I have been feeding my boxers chicken because there was nothing that was comparable to what we were eating that was remotely affordable. Much to my surprise I found this Purina One lamb and rice formula and my dogs devour it . To be honest , this is the exact same food they were eating before that got discontinued. Either way , glad it's back , even it is under a different name .

Lamb and Rice

My retired racer has been on the lamb and rice formula since I adopted her almost 3 1/2 years ago. She has done very well maintaining her weight etc. Something changed with my last purchase. Luna refused to eat it. She just ignored it. Hunger got the best of her and she ate some of it. This behavior continued the next couple of days. Something changed with the formula. She has done well on another brand.

Changed Formula

I bought this brand and the lamb piece flavors in September 2022. My 2 adult dogs and new pup loved the flavor and the lamb pieces. I just recently purchased again in a larger bag. I opened the bag and he had a stronger smell but I figured it was a while since I ordered. I spilled out the bag into a dog food container to keep fresh. When I went to feed the dogs, they turned their noses up and walked away. The puppy who usually will eat anything didn't even care for it. I called customer service and they said it would need to return for refund as their policy has changed from allowing a refund without return. I use to donate anything that was refunded and didn't need return. I unfortunately threw the box and the bag and it would have been difficult to drag 40 lbs to have returned. I ended up throwing it out. First time I had ever had to do this. I will shop other pet shop that still has a better return policy if and when possible.

Lamb and Rice Purina One

Our senior dog (14yrs, yellow lab mix) started to balk at eating the chicken kibbles in the "Vibrant Maturity" Purina One. As soon as we tried the Lamb and Rice (Purina One) she ate everything. But with other supplements for senior dogs, we've dropped the Vibrant Maturity until they come out with a chicken free version.

Great Food

Had trouble finding a dog food flavor that my one dog would eat and not get tired of after a few days. Lamb and rice he eats his whole bowl at every dinner..I highly recommend this product. It is healthy and he loves it. We don't buy cheap dog food it isn't good for your fur babies. Chewy is Great. They care about your babies and save you money. Been a customer for years.

Experience Review

Chewy.com is now the least expensive place to buy this dog food. The fact that it has free shipping is an added bonus. I had a very positive experience in shopping with chewy.com. Here is a picture of my dog, Taz, and he appreciates it too.

Ingredient checklist

We recently discovered our pup is allergic to corn, peas, rice, oat, peanut and tomato. I was having a hard time finding a food that fit all those criteria. I emailed Chewy with the list of allergens asking if they had any food that would work. The next day I had an email with 5 different options.

Great Quality

I’ve always fed my dogs Purina brand and my last two Purina Lamb and Rice . My dear Sadie who was Shepard Husky Mix lived to be just over 16 yrs old. My English Bulldog was over 13 yrs and a Sheltie over 15 yrs. My current rescue also eats Purina One Lamb and Rice and no tummy issues. I plan on having her a very long time as well. I’ve tried some other more expensive brands from the pet store and had to return it because Sadie and Daisy , my current pooch didn’t really like it.
