Questions & Answers

17 Customer Questions


is this food suitable for weight loss?

Answer by 4K2D1CApr 07, 2023
Nearly any dog food can be fed when your dog needs to lose weight. Feed the amount for their ideal weight vs their current weight, reduce treats, and/or increase exercise.

Are any ingredients sourced in China?

Answer by ChewyNov 19, 2019
Nulo's meat, poultry, and fish are sourced from North America, with the exception of some of their duck (France), lamb (Australia & New Zealand), and wild-caught fish (regions can vary based on the migratory path of the wild population). Their fruits, vegetables, vitamins, and minerals are sourced in North America as well as regions throughout the world, but are always traced and required to meet strict safety and quality standards. None of Nulo’s ingredients are sourced from China, with the exception of select vitamin supplements that can only be sourced from there.

Great for my Lil lady!

So Scarlett was diagnosed with type 1 diabetes with ketoasodosis when she was 8 and a half. She was in the ER for a week until they found out. She needed 2 shots

So Scarlett was diagnosed with type 1 diabetes with ketoasodosis when she was 8 and a half. She was in the ER for a week until they found out. She needed 2 shots of insulin everyday for the rest of her life. This came with a diet change and feeding schedule. I went through about 10 different dog foods trying to see who had the best protein, fat, to fiber ratio diabetics needed. She's allergic to chicken and lamb, and beef had too much protien and not enough fat. This food was the winner. I mix it with wet food and her hip suppliments and vitamins and shes 13 years and 7 months and doing great. Sure we have bad days but the good is still stronger. Good food is good fuel for her and this recipe has not failed me yet.

I've been using new love since it first came out it was a really decent food it didn't have a lot of garbage in it like processed pieces of chicken that really shouldn't be in anybody's food it's disgusting had deboned chicken and doesn't use a lot of fillers and it has gotten independent five-star reviews my only complaint is since you first started selling new low the prices have just substantially risen a lot they say it's because movie stars now finally found new low and now you raise the price I think that dog food that is a decent dog food should be accessible to everyone and the price is a little high

Helping my Shepsky a ton

We recently decided to make the switch to Nulo Grain Free to see if it'd help out German Shepherd/Husky's joint and arthritis issues. She's already in supplements and an anti-inflammatory, but we weren't noticing much improvement. After a 10- day transition to Nulo and being on it for nearly a month now, we are seeing a big improvement in our dog's activity levels. She has a lot less stiffness and has started playing again! Also, this food is more dense than what she was previously on, so the daily serving size is less. (So it might be more expensive, but it takes less each feeding so lasts longer!) Other than the obvious health benefits, I also appreciate the re-sealing bag!

Received a damaged bag so Chewy sent out a replacement for no charge, however made my dog sick. Diarrhea, vomiting for 4 days straight. Had to feed him rice with bland chicken to reset his stomach. Thank goodness, he didn’t become dehydrated that I needed to take him to the vet to be seen. . been reading the ingredients. I think the probiotic might’ve been too harsh for my senior dog sensitive stomach.

Loves It

The smell is not what I expected, but our dog loves it. He can be somewhat picky with his food, but went right for this.

Great ingredients

Both dogs are loving the food. Since I have large dogs, I wish the kibble pieces were bigger, or come in different sizes to choose.

In looking for a senior food and being an ingredient reader, I decided to try this for my baby girl. She would leave her previous foods but she always eats this right away. I’m glad I tried this food as she prefers it over previous ones I have tried.
