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).

Highly Recommend for Medium-sized (22lbs -25lbs)

Hills is the only dog food my veterinarian carries (she carries therapeutic versions only). My Australian Labradoodle (my 1st AL) is a wonderful dog, but a VERY fussy eater which is annoying. He's only 2 yrs. old and 21 lbs. I had labrador retrievers for years and never had this problem. Before settling on Hills small bites, I tried 4 other well-known, respected brands and always ended up giving almost full bags to my neighbor or son. I'm convinced it's the AL breed, not the dog food, but this version of Hills has been working (and my vet highly approves of it), so I feel very comfortable recommending it.

Oliver the Corgi

Oliver has been on this food for about 2-3 m. His coat looks great, his weight is good, and he’s very active. I switched to this food after realizing that the farm store dog food was great for the big dog, but not necessarily Oliver. He loves to eat and the small bites are perfect. I also trust a veterinarian recommended brand. Highly recommend.

Not My Dog's Favorite Food, But Better Than Some

I purchased this food for my dog because unlike some other dry dog foods, this food had less harmful ingredients than the majority of dry foods I have seen, and this food isn't grain-free, which I have read isn't recommended for dogs. I wouldn't say this food is his favorite to eat, he prefers human grade cooked food, but I feel this dry food is better quality than most dry dog foods I have seen.

dog didn’t like/upset her stomach

We decided to change to this food because we heard the best things about it after our doxie suddenly decided she didn’t like her food anymore, we did slowly incorporate it into her old food as well which she would be very hesitant about the new food but it wasn’t causing any problems until all her food was just this new food. We noticed she began throwing up every morning before breakfast time and sometimes just randomly in the day so we put her on a bland diet for a couple days which helped then got her a different brand of kibble, so far no more throwing up.

With all the rage against kibble these days, I find this kibble to be an excellent option for a 2.5 year old lab. She is fed five eighths a cup a day and enjoys it. Sometimes I add water to it to add flavor, or keep it dry. Either way, my little doggie enjoys it.

Adult food switch

My corgi is nearing one year, so I asked an online corgi page what type of food they like to use. I was recommended this type! My corgi loves this. I'm just taking off a star because it came to me punctured. The food inside looked okay, and he's been fine. Will continue to get this.

Probably most ideal of all the selections

As I have indicated on other Hill's foods, there seems a possibility that some dogs might not take well to certain types of food, but this chicken and barley has proven to be reliable. Not to mention my experience shows dogs definitely prefer Hill's over other brands. It's a matter of whether you think the extra cost is worth it. Since I am relatively new to using Hill's, it remains to be seen, but I think it may be important to heed the instructions such as "Adult 1-6" versus "Adult 7+," etc. I suggest paying attention to that. It appears that not doing so MIGHT cause stomach upset in some dogs. But don't let that scare you away. Just monitor it at first until you see what is best for your dog.

Great food good price

I used Chewy for the first time as the price of my dogs food was just going up in price every month locally and was getting harder to find. So far so good

Great as always

We are very happy with our service from Chewy. There were a couple times the boxes came damaged, not their fault, but they compensated us. We recommend Chewy to our friends.

Holy price change

The price of this dog food has gone up 20 FREAKING DOLLARS and I have been ordering this for years. Time to find something else for my pup. Sorry Chewy, you lost our business.
