It is great value, the price is very reasonable and comparable to other healthy brand foods. Our dog however, for some reason, is very about what she eats and we have found that Fish isn’t her favorite. But I think she is exception :-) for our pop I guess it will have to be some red meat kibble product, I don’t know why that is. I recommend this product.

Puppy Approved!

My puppy was eating Hill's Science Diet, and the food would sit there all day, and I felt like he was eating it at night as a last resort. Bought Nulo purely based

My puppy was eating Hill's Science Diet, and the food would sit there all day, and I felt like he was eating it at night as a last resort. Bought Nulo purely based on the reviews here on Chewy, and the puppy runs to the bowl in the morning to eat. Forgot to transition him slowly, so he got the runs after the first day, but this issue goes away if you follow the food transition recommendations.

I enjoyed saving money with a coupon from Chewy and the order arrived timely.

My dog seems to really like Nulo Challenger dry dog food. I enhance it by adding a freeze-dried raw topper.

Loved by the pickiest of our pack!

Everyone loved it! This food caused no digestive disturbances and everyone from a very picky Papillon to our Bengal cats thought it was delicious. We have four dogs

Everyone loved it! This food caused no digestive disturbances and everyone from a very picky Papillon to our Bengal cats thought it was delicious. We have four dogs that all enjoyed the flavor and size of this food. Our cats also felt that it was perfect to steal and snack on whenever they got the choice. We have big, medium, and very small dogs and the kibble size was fine for everyone. I was pleasantly surprised to find that on opening this food did not have the rancid fat smell that is often found in highly palatable kibble. We will likely be buying this food in the future.
