Fast Shipping

This review is more based on how amazing Chewy is. My dogs love this dog food but they also think sticks and mud are the greatest thing since sliced bread so its not hard to please them. But I ordered this dog food Saturday morning at 7:30 and by 1:30pm Sunday, it was already delivered and waiting for me on my front porch! Their shipping is incredibly fast and free (if you spend enough money which we always do). I will never buy dog food from the store again, Chewy is the way to go!

Fantastic food

My 1 year old Golden Retriever was on purina pro plan as a puppy, and struggled on and off with very bad diarrhea episodes. After trying a few types within the purina pro plan brand, our vet suggested we switch brands entirely. I chose this food and diarrhea is gone! No episodes at all since switching. She loves the food too. I highly recommend this food and brand!

Small hole in bag

Love the company overall! Small hole on side of the bag which I have seen before working as a fork lift driver at a fulfillment warehouse.

Perfect kibble for cleft pups!

This is the only kibble (we switch between lamb & chicken) we'll buy now. It's the perfect shape/size kibble for our 2 yr old boxer with hard & soft palate clefts. No issues with it getting stuck. She and her 4 boxer brothers and sisters love it!

Great taste

I switched from my previous dog food I used based on our vet. recommendation and our dogs love this taste. I use to have to wait out the time for them to eat, now they gobble this up like its cake.

Careless delivery

It was raining "cats and dogs" and we saw on the security cameras the delivery person THREW the two big boxes over the front yard gate, they landed on the wet ground broke open, and all the food, pond tablets, and other contents got soaked, rendering them totally useless!
