IBS loose stools

My buddy has IBS. Husky doodle mix he grazes not a gulper of his food. Sometimes he would have accidents in house. Always loose watery stools. I would let him out at 11 pm and by 6 am he’d have an accident. During pandemic I could not get this food which had stopped all his problems! No he has been back on this brand and back to normal stools

Great food for dogs with sensitive stomachs!

This dog food is just what we needed for our black lab/pitbull mix with digestive issues! Before discovery of this food our poor pup vomited daily in the morning because the food wasn't digesting for him. Thankfully, he no longer suffers such and it's all because of this food! Thank you Purina!!!!!!!

Pups love it.

My 6, yes 6 dogs have been on Nutro for a year and a half. They finally decided they didn't like it anymore. Two of my dogs were having diarrhea constantly. Their other food never smelled that great. This one actually smelled good for dog food! When I opened it they ran to the bag. This is the first time they have ever wanted dry food alone. They tore it up! The diarrhea is subsiding as well. I would definitely recommend this.

Awesome service. Great prices. LOVE this food for my fur babies. We have 5 dogs today and strive to feed them the best. We feed this food to 2 German Shepherd's, an Australian Shepherd, Pitbull mix, and a standard poodle. They love it!

not in Stock

The Purina One small bites 31 lb bag hasn't been in stock last 3 orders. 1st 2 times I was offered 2 16.5 bags in replacement. This time I was offered nothing. I had to call and find out what was going on. Still wasn't offered a substitute. Couldn't tell me when this item would be available. So I went on line and picked another variety and asked representative to ship me this one. I received a 16.5 bag instead of the 31 lb one but least I got something.

Dog Loves It

My dog has always loved the Purina One formula's because there are chunks of real meat in them. Now you have to get the Plus versions to get the meat and she didn't like some of them. This formula has helped keep her on a regular bathroom schedule and she eats every bite.
