  • Great quality! Doggies love it

    By on

    Excellent! I've been trying to find a diet/low calorie dog food. I can't afford the Prescription Science Diet so I decided to try this. I was worried my dogs wouldn't eat it. I've been giving them a different brand that I found out is very high fat. They seem to enjoy the taste. The kibble is a size that they like too!

  • My Sheltie loves it!

    By on

    My Sheltie was overweight and just plain heavy, I can tell he has lost weight in a few weeks, he's not so bloated and his stools are good, no complaints about this food, he loves the taste too. No problems during switch over from the last food, which is rare.

    I was very happy with the rep that helped me complete my 1st order. This particular brand of dog food is not always carried by the store I normally buy from. The order went smoothly and the delivery was very quick. Very happy with this service

  • Too Big to Chew for the Meal

    By on

    My dog started to eat the dry food. She ate a few pieces and left the rest. When I was mixing it with the old food she would leave the Hill's food in the bowl. I think the pieces are too big and she does not like it.

  • Split in Seam

    By on

    This bag arrived with a split in seam . Food was all over box. I was able to tape the split shut and as the food was still fresh decided it was ok to feed my pups. Unfortunately they don't seem to like this food.

    Ordering from Chewy.com is the best decision I ever made. I ordered food for the first time recently but have ordered dog treats for a long time. Easiest shopping I have ever done. Customer service is amazing.
