Not a good fit

I changed my order to Purina One Plus, Digestive Health because it was less expensive than the Hills Science Diet but it isn't good for my dog. She has a very sensitive stomach and this does not work for her. Also, she eats twice as much, so it's not a bargain. I'll go back to the Hills Science Diet on my next order.

I had all but given up finding a dry dog food that my 2 German Shepherds would eat, after deciding that the dry food they'd eaten for 2 years was no onger acceptable. I don't even have to mix it into their canned food. I just put it in the same dish alongside the wet food. ~ I got the Digestive Health, because the younger shepherd would occasionally throw up and have loose stools. ~ This seems to have cleared those 2 items up very nicely.

Hard to find locally - so glad Chewy can ship!

I found this probiotic food once locally, but then discovered it's not always in stock. The food really helped our dogs' digestion, so I was determined to use it again. Thankfully Chewy can deliver!

Donation to Animal Aid Society in Hampton, VA

Purina One Plus was on the Christmas Wish List posted on the Animal Aid Society's website (located in Hampton, VA). It is a no kill dog shelter run by volunteers. The package arrived in only two days and I delivered it to the shelter as a gift to others from my dog, Winter Weathers

3 Doggos w/ Happy Tummies

I have 3 Bullies. One older girl and two adult sisters. Each have their own issues But with this food, all of their needs are met. They enjoy the taste of it and eat it like its going outta style. If your pupper has a sensitive tummy, give this a go. And Chewy shipped it stupid fast, (literally got it the next afternoon)

Vet recommended

My beagle mix had a problem with her digestion and got sick. After treatment, my vet recommended this food and only Purina treats for my sweet girl. She is doing much better and likes her new food.

Bag torn inside box

Dog food bag was all over inside of box. I really did not get all food entended to be in bag. Handlers should be more careful with preparing or handling package! Replacement bag would be nice.

My chihuahuas love this food and also all four of my cats are always trying to eat this when ever they can sneak into the chihuahuas bowls. Lol.

Dogs like food

Switched from Purina One to the Digestive Health because we have one dog who gets an upset tummy. All dogs seem to love it and are doing well.

Not Happy it didn't help.

I bought this in place of Authority Gut Heath, and almost immediately my dogs had allergic reactions. I had really hoped this would be an alternate food source as the Authority is in limited supply.
