Questions & Answers

Does science diet puppy contain chicken by products?
Answer by ChewyMay 29, 2020
The Hill's Science Diet Puppy Healthy Development Small Bites Dry Dog Food does not contain chicken-by-products.

How to switch to different food, percentage to old & new?
Answer by ChewyAug 22, 2018
This varies depending on the individual dog. It could take 5-7 days. For example: Day 1-2: 25% New / 75% old Day 3-4: 50% New / 50% old Day 5-6: 75% New / 25% old Day 7: 100% If your dog is experiencing upset through the transition, then you can lessen the ratio as you see fit.

We have a puppy who is about 5 pounds and close to 4 months old. We have her now on Small paws, but since she is bigger now want to go with the next bigger size kibble. Are the ingredients the same?

Great service!

I recently purchased dog food from Chewy.com, and I am very pleased with the service that I received. My order arrived on time and in perfect condition. The product was exactly as described and my pup loves it! The prices are also very competitive which is a huge plus for me since I have a hungry pup to feed. Overall, great experience with Chewy and would definitely recommend them to anyone looking for pet supplies or food!

Dry food

as I remember I used to feed my puppies and I like how it was made to make the digestion clean tidy but now I don’t know what the difference in their formula my puppies didn’t digest it well, stools were not clean and normal. It’s too bad I can’t use it anymore

My Baby Girl loves this stuff and it’s got good vitamins in it to give her bones, coat, skin, everything a healthy start in life!! It’s a little expensive but that’s ok, she’s worth it!!

Vet Recommended

After talking with the vet about the tummy troubles my poor pup was experiencing. She hoped onto Chewy and showed me this specific puppy food and told me how highly she thought about the brand and gave it a glowing recommendation. It has done WONDERS for my puppies tummy troubles and he seems to like this food a lot more then his previous one. I definitely will be sticking with Hill’s Science Diet from now on.

Glossy Coats

I first got this for my malnourished rescue, and it transformed him. It helped him pack on weight, and his fur is so shiny, it gleams in the sun. My senior dog kept sneaking bites of the new food so I started buying him the senior blend. Everybody is healthy and happy, with the best hair on the block. I recommend this brand for everyone when asked what I feed them.

Hills Science Dog food

Have been using & purchasing this item & never a problem, but this bag must be old & no good, my 2 dogs wouldn't touch or eat it. Had to purchase another bag at local pet store. Have never had a problem like this.

Love Science Diet

I have been feeding my dogs Science Diet for 20 yrs. Our newest pack member is a 4 month old Rottweiler. We got her when she was 3 months old and she put on 10 pds in a month! They have all loved Science Diet.
