How many cups are in a 35 pound bag


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.

Doubt the health benefits

My dog just turned 6 and was diagnosed with diabetes. He has no risk factors, breed-wise or environment. He's never been overweight; he's active; minimal table scraps

My dog just turned 6 and was diagnosed with diabetes. He has no risk factors, breed-wise or environment. He's never been overweight; he's active; minimal table scraps (what the baby drops). He's only JUST turned 6. He's been eating Hill's science diet without exception since we got him from a reputable breeder as a puppy and that's what they were feeding him. Thought paying more for dog food would prevent major health issues down the road, but I guess not. There's barely any regulation for human food, so why would there be for dog food, I guess. Probably the same stuff as Ol' Roy, just four times more expensive. Save your money.

Great flavor, my dog likes this more than peanut butter and loves peanut butter. Not a great odor to smell but pretty easy to get used to. Only really smells when not in air tight container and in bulk. Hardly any smell when measuring out a cup or so at a time for feeding. Would not store in living room personally.

She has never been so happy with her food. Her energy levels are up up up and she’s back to her bouncy happy self. All she wants to do is play and cuddle. It’s truly amazing and heartbreaking at the same time to get to see that loving spirit of hers once more. We found each other during the darkest parts of both of our lives and she’s always been there for me. I’m doing everything I can to make sure she’s as happy as possible for her last few years. Running to the bowl for this has definitely become one of them.

I would buy more stuff from chewy if I could use Autoship and get the deal that going on at the same time. Example I get the Autoship with the discount, the next shipment is 5% off. But I have a 20% discount I can't use on that order. So I cancel the Autoship and get 20% to 40% off from some one else. I have 2 cats, 2 dogs, 2 turtles and 3 lizards, but I'm only buying dog food because of the way it works. Everyone wants a little discount when they buy stuff.

Abcessive itching

she gnawed all the hair off her shins on each back of legs and biting her nails. So Dr Boasso had tried for over 6 months and just didnt like giving steroids so she put her on Royal Canin to easily wean her off of Hills. Then we will start the process of elimination if the itching returns/ so far its getting less on her licking her paws.

Bullies Love It!

I've been free-feeding them this food since they were 2 yrs old. Now at 8 they're doing great on it. Maintaining a good weight and nice coat. It's a bit pricy,

My dog loves this food and does really well on it. We actually buy the 35 lb. bag, and have never had a problem. This time the bag somehow got a hole poked in it when it was packed in the cardboard Chewy shipping box. When it got to us I had a shipping box full of loose kibble. Never happened before, hope it never happens again.
