Tuna

It's awesome puppy chow for Mickie, her tummy was a little sensitive at first, she had a little diarrhea at 1st but after I whined her from the old treatment puppy chow by giving her raw tuna cans every morning she adapted very well, she has more energy on this food, but I can't stress enough by changing a die of a dog. That's a pure bread. You'd have to do it gradually. And I did that by giving her raw tuna every morning, by opening up cans of tuna and mixing it with this puppy chow

I have fed Purina One High Protein for a long time, and I wanted to get my new puppy on it as soon as possible. She's been having an upset stomach on the food she came from the shelter on, and I heard the fish-based foods were good for sensitive stomachs. Her stomach does seem better, and she likes the food, but SHE SMELLS AWFUL. The tuna coming out of her glands makes her smell like an unkempt pig farm 24/7. It's unbearable. Like an idiot, I plunged right in, knowing I trust Purina, and bought the 36-pound bag, so we're stuck for another month or two, but after that, we're going back to beef and salmon or turkey and venison.

FedEx delivery is not good. I live in a trailer park and my package was delivered to the farthest street from my house. Not the right street nor the right number. I am older and have it delivered so I don't have to carry it. This Delivery totally wrong! Luckily the person who received it let me know.

Wow, my dogs LOVE this. I purchased another bag (a different flavor- salmon/beef) as well and they are obsessed. We came from Purina Pro Plan due to the constant cost increase and they actually prefer it so much more than Pro Plan. There is never a leftover kibble in the bowl and they happily sit and wait for their food when it's dinner time. Poops are also consistent and solid, very little gas (because cmon, dogs are gonna fart anyway). Overall a great food.

I had purchased this for one of my picky little guys but my neighbor had a house fire and their pups food was destroyed along with much of the belongings in the home. I took them this bag and the owner told me they had never seen their dog so happy to eat dog food.

Not sure if a bad batch. Have been ordering this brand for about two years. New bag came in and dogs not eating. They use to bounce up and down so happy for feeding time. Chewy is replacing bag and will see if that makes a difference. If not, going back to pro plan or calling purine to ask if changed the formula.

When I went to a larger size bag of dog food that I purchased through you/chewy the brand was the same. The name was the same, and the flavor was the same, but the dog food itself were larger in size, noticeable but not extremely larger. So I didn’t really like it that the size was different. Also, your large bag dog food was all the same color. In the smaller size bag, the triangles were the dark pieces and odd shaped pieces of food were tan. Your big bag of dog food I did like that they were all the same color because my dog seems to favor the odd shaped tan one’s best and with your dog food it was all the same color. The change was a concern to mine as I was going on vacation. He only had the food for three days before I left and because I was packing my suitcase and he was a little nervous so that factored into his eating so I wasn’t sure how he was taking to it.

We got this as an item a help to keep her coat beautiful and it seems to be doing well. It is a part of a mix of three dog foods to insure she has a good balance of foods that meet her needs. My only complaint is it is so expensive. Great Danes eat a lot. I have always been a Purina fan.

I've never been a fan of purina but this was recommended to me by a friend of mine for a puppy that I'd gained. His food is being switched to a brand that meets his specific needs more. I use to bits of meat as a treat for him when he's waiting for his food.

I needed something to help with my WGS's dry skin and healthy fats as they are prone for joint issues as they age. This formula provides salmon that wont break my budget and without having to buy supplements (yet). The best part was that my dog wanted to eat it. The texture and richness of it drew her in and she's now excited for meal time. Over 6 months now and she's better balanced in her mucle to fat ratio and there's been a significant improvement in her skin and coat. She's happy and healthy which is all I could ask for.
