Makes your dog stink
By Bill on Apr 3, 2021
The only reason it gets one star is that my Bkack labradors' coat looked great on this food. The lack of anymore stars is because it makes your dogs coat and breath stink like fish. Not kidding. Our girl smelled awful, could barely stay in the same room. Took a year to figure out that it was the food, not our dog. Switched foods and it went away in about a week. This was not flatulence, but a stench emanating from her skin and mouth. Awful stuff.

SERVICE COULD HAVE BEEN A WHOLE LOT BETTER
By KIM928 on Apr 3, 2021
Great product but when I called right after placing order to request that the two large bags of dog food be split and placed in separate boxes they assurred me they would. But nOOOOOO it did not happen. I am expected to lift over 70 pounds on my own!! So frustrating and on a rainy day at that.

Dogs love Hills Science Diet
By Runbikeswim3 on Jan 23, 2021
Our family is blessed to have 5 dogs who are not picky eaters or have allergies. We compared prices to local stores and Chewy had the best. While our dogs are not picky we do have other health issues which determine what food we can/cannot purchase. We own a Great Pyrenees and 2 Newfoundland dogs ages 6 and 4. Because they are giant breed our Vet prefers us to keep them at a safe weight.All 3 are good eaters - our newf has kidney dysplasia and is on very specific food both to help him maintain his weight but also to help his kidneys stay as good as we can. With blood tests every few months Hills science diet food both canned and dry have worked wonders for our dogs.

SD adult large breed- 1st order
By GoldenMom on Jan 12, 2021
I decided to try regular adult for a month, instead of the sensitive stomach/skin product. It was a little less expensive, which is nice. I am picking up larger piles in the yard however. All in all- she likes it and I'm not seeing a big difference in her. I think I'll likely stay with this on my next order.

New food tryout
By JLGM on Feb 5, 2021
Took a few days for my giant dog’s system to get used to this new food. Once done he’s enjoying the taste and I’m enjoying the pellet size which fits into his maze-like bowl to slow down his gulping. Very pleased.
