Hills Science Diet - Adult Large Light

I've had giant breed dogs since 2002. On the recommendation of my vet, my all puppies have been raised on this brand of kibble. They love the taste and have all grown up strong, healthy, and well developed.

Hills large dog food

I called in asking about why my dog food size was smaller than before. The CS rep went into my account and found out that I ordered wrong She was very polite and patient and went into my history to let me know I what I'd ordered before. Thanks a million guys!!

unsure....possible allergens?

We purchased this for our yellow lab who had been eating the original Hills large breed formula; within a few days she was scratching like crazy, and when we pet or brushed her it seemed that her skin was itchy everywhere. We switched back to the original Hills large breed food and just as before it only took a few days to notice a difference - the itching and scratching stopped. We did not change anything else but this food (and don't feed her people food) so my conclusion is there is something in this formula that may cause issues for sensitive doggies.

My dog would be bald without this

I put my dog on this food bc I suspected he had pancreatitis. After taking him to the vet and they told me he doesn’t seem to have pancreatitis I changed his food. My dog lost half his body hair. They put him on special shampoo and nothing worked. He had bald spots. I switched him back to this food and all his hair grew back. This is how I know this food has all the key nutrients he needs to stay healthy.

Quality food but

I certainly cannot give this food a bad review. We adopted a Saint Bernard and this was the food he had been eating at the foster and he likes it. I bought more so he would not have a drastic change. One thing that I cannot necessarily blame on the food is he is biting/itching his limbs quite a bit and I have to assume this is some sort of allergy which I am trying to work out and I will be starting with the food. The other is that it has a HIGH residual - meaning for the amount of food he eats, he poops A LOT! For my former XL dogs, I always bought a different brand for this very reason - less waste and less poop.

Long time super satisfied

My pets and I have been Chewy customers for quite a while now. We have always gotten exactly what we ordered, quickly! My Lab loves the "Light" Science Diet that I mix with green beans to keep her weight down. The cat is a bother. She always wants more of the treats. We have had to limit those to her, because she has gained more weight than the vet wants! The only thing I have against Chewy is that their package are so heavy. This old body has a lot of trouble getting it up the entry stairs.
