Auto shipping was working great at first but each month it's taking longer and longer to be shipped. Last month they told me it was taking longer because of people buying more things for Christmas. And this month in January it took nearly a week to be shipped. I'm finding if you order things direct it only takes 2 days from the time of ordering to arrive. So I'm going back to direct ordering and doing away with auto orders. I'm tired if running out of food and having to buy some from the store. Auto shipping is costing more not less because of that.

This is the second time trying this type due to recommendation. The first time I just thought that it was my dogs with summer season shedding and itching. When I told him I know it neighbor this she said her dogs doing the same thing on the same food and she switched so I did too, but thinking maybe it was an off batch I would tryit again. Call me a fool. I bought the big bag and I’m throwing away 3/4 of it. I am now trying the salmon and rice for sensitive stomach and skin. If the same thing happens, I am done with this dog food. I hate throwing away dog food and switching my poor dogs, but I do not recommend this kind, especially if your dog has sensitivities.

It really helped our boy!!

Nash is 8 and was having a sensitive digestion issue all of a sudden. Spent so much money on vets, tests etc. They wanted to put him on a super expensive food brand

Nash is 8 and was having a sensitive digestion issue all of a sudden. Spent so much money on vets, tests etc. They wanted to put him on a super expensive food brand. Decided to give Purina one a try first after reading reviews. We saw almost immediate changes when he began eating this brand. It's been over a year now, and he's been so much better with just an very occasional issue.

I love having our dogs food delivered to our house. Our problem is the delivery person. We are a 61 and 64 year old disabled women. We have put on the app that we want the box put on the ramp. Our German shepherd will not jump over the deck fence and gate. I wish they would put it on the ramp so that it makes it easier for us to get into the house.

I've tried dry/wet mix with canned and pouches, even other varieties of dry, but my Wolfhound mix would turn her nose up at them. My daughters dog loves this as well and has a sensitive stomach, so I gave it a try. Probably the first one she will consistently eat.

Great for Sensitive Tummies and Picky Eaters

We have tried so many different dog foods for our sensitive digestion and very picky Dalmatian and grabbed this bag as a last minute resort in the grocery store

We have tried so many different dog foods for our sensitive digestion and very picky Dalmatian and grabbed this bag as a last minute resort in the grocery store in a pinch and it turns out our dalmatian absolutely loves this dog food. It has been smooth sailing for her and we started feeding it to our GSP and mini dachshund as well. All three girls love this dog food. So far so good, they have not turned their noses to it yet, so that is a huge huge plus for us.

Poor handling

The delivery company mishandles my shipments regularly and bursts the cans of food open when they DROP the box! I understand it’s heavy, but they have to know how

The delivery company mishandles my shipments regularly and bursts the cans of food open when they DROP the box! I understand it’s heavy, but they have to know how to handle it better! Use a two wheeler!! Over half of the case has to be thrown away because they arrived open!

Great food until it got stinky

Switching to this food solved Juno’s GI problems. She’s been on it for 3 years and her heartburn and diarrhea cleared up. The problem is the last two bags we got produced the most foul odor. The first one stunk and Chewy replaced it. I just got the new bag and that stinks just as bad. It’s the same flavor she’s always had and, to my knowledge, they haven’t changed the formula. I’m not sure what’s going on but I’m going to switch to something else.

Came when it was promised and saved me time and energy to go get it. These are big bags of dog food and the store thatI would buy from would only have one big bag and I like to get two cause I use them pretty frequently.
