What is the difference between the small breed advance fitness and Hill's Science Diet Adult Small & Toy Breed Dry Dog?
Answer by ChewyJul 19, 2018
Both formulas have less than 1% difference in caloric, protein, fat, and fiber content. The Hill's Science Diet Adult Advanced Fitness Small Bites formula uses fresh chicken as the first ingredient instead of chicken meal and has an added blend of omega-6 fatty acids.

please compare the small bites chicken and barley food (science diet) vs. the adult chicken and barley formula (regular and large bites) as my puppy approaches 1 year and is between 25 - 30 lbs and I would like to transition from the puppy formula
Answer by ChewyMay 07, 2020
Both of these foods share the same exact benefits and ingredients. The only difference is that the Small bites formula offers a small kibble size.

My puppy is now a little over 1 years old & looking to purchase the adult small bites if the ingredients are the same in puppy and adults small bites size do I need to be slow on introducing the adult brand as far as for the stomach upset.
Answer by ChewyJun 01, 2019
A gradual transition to any new pet food is important to avoid digestive upset. To transition, it is recommend to mix your pet’s current food with the new food. Over 7 days, gradually decrease the amount of the current pet food while increasing the amount of new pet food.

What is the phosphorus content?
Answer by ChewyJul 14, 2020
This variety contains approximately 0.51% Phosphorus content on an as fed basis (0.57% on a dry matter basis).

Dogs vomiting

I’ve been feeding this to 4 of my dogs. My 2 shih tzus have been vomiting for a week now since receiving this bag of food. They did not react this way when I ordered the small bag. They’re so sick that I have to stop feeding them this food and throw away the entire bag. So disappointing.

This dog food is the only thing my dog will eat. Although I can rave about it all day, I am absolutely amazed by the Chewy team every single time I order. Mia was down to the last few kibbles of her last bag of food and without a mention of it, the bag was at my doorstep in less than 48 hours. So grateful for the Chewy team and how hard they work every day for all of the pups around.

Missing delivery

I was notified that my auto shipment was delivered sometime during the day yesterday. When I arrived home, I learned the shipment was not received nor was there proof of the delivery on my ring camera.

Great dog food

Our Queensland Heeler has been on Hill’s Science Diet, per our vet’s recommendation, since she was a puppy. She is now 4 years old and still on it. It seems to work for her so no reason to change.

It's a no go for this one

I tried to switch my female dog to this one from the Hill's puppy kibble after her last little of puppies but she just picked this kibble out and left it on the floor. My male hates it too. Not Chewy's fault, I guess it's the barley flavor? Not really sure. At any rate, she was spayed 4 days ago and I'll keep her on the puppy food until she is fully healed and deal with finding a suitable food then

New item

I’ve been ordering for about 6 months and over the 6 months the item I ordered was no longer available on 3-4 different occasions. This may force me to buy locally since they don’t like the last food ordered. . One dog has no teeth so I have to have small pieces.

collar was as expected, excellent and of course the dog food is great. Kind of wish you had smaller bags as that large is a little difficult to use to start with, however, no big deal.

Fast delivery is right on time.

Love the purchasing and information process. My son’s dog, Jade has her Vet records on file and the speed of delivery is off the chain.

Hills Science Diet

30 lb bag had about a one inch tear in it. No idea how long it has been there so I don't know if it has affected the freshness.

Adult Small Bites Chicken & Barley Recipe Dry Dog Food

both of my Chihuahuas love this food. We also feed them the Science Diet wet food. One of them is on prescription wet dog food. She actually loves it. We struggled for years to get her to eat. Not a problem any longer.
