Are the chewy pieces chicken or soy?
Answer by ChewyJun 03, 2019
The tender meaty morsels in this formula are made from chicken.

We are getting an older mixed breed puppy about 7 mths old unsure what she is exactly, they said husky /German Shepard mix I think catahoula possibly maybe Australian Shepherd maybe some German really unsure. I didn't know at about 7 months or so she is 47-50 lbs. Would this large breed be ok?
Answer by ChewyDec 08, 2019
This formula is intended for large breed puppies. There are individual differences in growth and development for all breeds. Due to their unique growth rates, it is critical that young adult large breed dogs between 6 months and 2 years old get the balanced nutrition they need for growth without excess calories. Ideal levels of protein and fat help balance growth in puppies and help maintain an ideal weight in young adult and adult dogs. We always encourage pet parents to speak their veterinarian to ensure their furry friends are meeting their nutritional needs.

What a Great Surprise Chewy!

I had received the wrong puppy food on last shipment. I did a review of that because it gave my 4 month old lab the diarrhea. Stil trying to get her on the mend. Chewy sent me a free bag of the right puppy food!! 🐶 Thank you again Chewy. Was quite a surprise when i received the email.

Absolutely GREAT!

My dog is a very picky eater & she’s absolutely loves this dog food. I’m looking forward to seeing her growth results because we have tried so many different dog foods & so far this is the best I’ve seen her eat.

Just about to find out!!!

Changed food for our Coonhound puppy. Have had Purina products in the past, so I don't foresee any issues at all.

Purina one puppy chow

We just got a golden retriever puppy and she loves this food! Our other dog, a beagle, enjoys it just as much as she does!

Great puppy food

I had to change my puppy's food because he just stopped eating his old food. So far so good. I have an older dog on the adult version.

Would recommend

We have a picky Corso, she's 7 months old and we want the best food for her. We have tried so many brands and she either ends up with an upset tummy or skin problems. We just switched from IAMS to this and her stools have been normal and she hasn't been itchy. We plan to keep her on this since she loves it and we love the results we've seen in just 2 weeks! I would highly recommend this food.

Finally-a food she loves

I have tried a few different foods with my chocolate lab, Chelsey. I would buy the smaller bags and try to find something she will like and continue to eat. Finally found it. She loves this. It has some soft pieces in with it and she acts like I put them there for treats for her. Lol. I will continue on this food for quite a while before changing over to the adult.

A big bag of healthy food

I was surprised to see how large the bag was. My puppy liked the food so much when I first introduced it to him. He has gotten slightly less excited about it but I am comfortable feeding it to him because of the natural ingredients.
