Dog Enjoys H.S. Large Chicken kibble With Healthy Grain For Heart Health

Never find in stores but Chewy always has it, thanks! Very easy to put a crushed-up treat or small dehydrated liver pieces on top of the kibble. Read that it's good

Never find in stores but Chewy always has it, thanks! Very easy to put a crushed-up treat or small dehydrated liver pieces on top of the kibble. Read that it's good for dogs to have 'some grains' daily for their Heart Health so we are thrilled it has good grains for our dog's heart. Our 75 pound rescue has a H.S. can in AM & this H.S. dry kibble in PM. Also, great for his sensitive stomach.

My dog loves this food.

I fed my last shepherd this food and decided to feed it to my Alaskan Malamute. The dogs like it and I prefer the ingredients to other brands for the price.

Kibble is good sized (smallish). And we added a toy.

THANK YOU for the possibility of adding something to the delivery of this food. We could add a toy, without paying more postage. Much appreciated!! And the size

THANK YOU for the possibility of adding something to the delivery of this food. We could add a toy, without paying more postage. Much appreciated!! And the size of this kibble isn't much bigger than the Puppy version, so we mix it with little dog treats, and we use it in training and in Rufus' interactive toys.

Dagger Won't Eat It

I thought this was the same recipe he has been eating, and while we graduated from puppy to adult when he turned 1 last month, I was still feeding the original chicken

I thought this was the same recipe he has been eating, and while we graduated from puppy to adult when he turned 1 last month, I was still feeding the original chicken & brown rice formula. Researching labels, I noticed "Large Breed" meant over 50 lbs - or maybe I assumed - and Dagger is right around 52, so I opted for Large Breed this time. The pieces are HUGE and he didn't like chewing them. Normally he is a voracious eater, but he started getting picky, then turned his nose up this morning, and came out to the kitchen looking for something better. I am now stuck with a 30-lb bag. I just bought a couple small bags of his regular sized kibble to hold me over, but I will order something else when I get back from vacation.

The bag was destroyed.

I love Chewy but this was a first. The busted and whole bag was all over the shipping box. First time putting her on adult dog food so I can’t say how she does on

Delicious

My dog has a sensitive stomach at times if we feed her certain things even if it’s healthy she’ll get the gas. This food has been amazing. There’s no gas.
