The 5-pound bag contains about 22 cups of kibble, the 15-pound bag contains about 65 cups of kibble, and the 28-pound bag contains about 121 cups of kibble.

The fat content is 7.5% minimum, what is the max?

Answer by ChewyJul 03, 2019
The recipes are formulated to target the minimum fat content that is provided in the Guaranteed Analysis, any deviation from this as-fed percentage would be minimal. Please speak with your veterinarian to ensure this value is low enough to be a suitable diet for your pet.

how long is the shelf life after opened?

Answer by ChewyMay 10, 2022
Manufacturers establish “best by” dates to ensure the safety of your pet. Look for the expiration date on the back or bottom of your pet's food bag or cans, and plan to use up the food before that date.

Works for weight loss

My dog has been on this for nearly 8 months now, and she’s lost 7 lb, and that’s with less exercise and still getting some treats. So the food absolutely works!

My dog has been on this for nearly 8 months now, and she’s lost 7 lb, and that’s with less exercise and still getting some treats. So the food absolutely works! The kibble is a good size for large dogs too. However she’s always had problems with chicken. I am glad the food worked for her weight loss, but her skin has been breaking out in itchy patches since switching to this. I wish they offered a chicken-free version. Unfortunately I’ll have to switch her, but I’ll still recommend this to others.

Pancreatitis survivor

My name is Rosemary...woof! I'm a 24 lb rescue dog who has struggled with vomitting and diarrhea since September 2017. My owners tried everything to get me better, numerous fasts and diets...finally in December I was so sick, on my 3rd visit to my vet, I was finally diagnosed with pancreatitis. I was placed on antibiotics and eventually given that prescription diet (which did work for me BUT TOO EXPENSIVE). My owner asked my vet for an affordable alternative and he recommended this food!! Thank goodness!!! While my owner does feel it's expensive and wishes the price was even a few dollars cheaper, it is a low fat food that meets my needs and I haven't pooped so good (or had so many normal stools) EVER in my life! I love eating this food and I am a happy dog once again! If you were recommended a low fat diet for your pup or dog I HIGHLY RECOMMEND this food! Thank you Natural Balance!

Neko the Victorious

I have a rescue bait dog from a dig fighting. Neko!!! Aka Fat round and low to the ground.Neko is Pitbull and English bulldog mix. He is allergic to so many things

I have a rescue bait dog from a dig fighting. Neko!!! Aka Fat round and low to the ground.Neko is Pitbull and English bulldog mix. He is allergic to so many things and it's hard to find a diet food that doesn't break him have allergic reactions. This Fat Dog food has been a miracle food for him. He loves the taste and since he's been on it he has lost 10lbs. I did have to get a trap or slow feed bowl for him because he eats so fast it upset his digestion. So if you have a dog that needs to loose weight I would highly recommend this food. 100% best food for my Fur baby Neko . Who by the way is by vet's opinion is between 12 and 14 years old. Thanks for having this food available. I'm one happy Pitbull Mama.

Amazing Outstanding Quality Food - Dog LOVES It!!!

A year ago after my gorgeous Pembroke Welsh Corgi, Oliver was finally altered; he gained far too much weight far too quickly. Fat Corgi syndrome!!!! Help!!!! Oliver

A year ago after my gorgeous Pembroke Welsh Corgi, Oliver was finally altered; he gained far too much weight far too quickly. Fat Corgi syndrome!!!! Help!!!! Oliver is a very active dog naturally. He did slow down a bit after his alteration and also became very interested in absolutely anything he could get his chompers on; its as though he is always on a mission to find food...any food. Oliver lost 10lbs easily on Fat Dogs over the course of just a few months AND I mix in a few oz of fresh ground beef, turkey, chicken etc and a tad of olive oil and he still lost weight! He loves dinner time and licks out every single drop from his bowl. He looks amazing at age 10. Gorgeous coat and great energy level.

Great Scott!

My Scottie popped up to 30 pounds and my vet wanted to get her down to 24/25 pounds because she had a luxating patela on her right hind leg. She usually gets 1/2

My Scottie popped up to 30 pounds and my vet wanted to get her down to 24/25 pounds because she had a luxating patela on her right hind leg. She usually gets 1/2 cup of kibble in the morning and 1/2 cup at 5:15 with a couple tablespoons of no salt added canned veggies. The first bag was mixed with her regular food, she liked it and lost weight but put some back on in winter. Last summer within four months she blew out both her ACLs. Two surgeries and $10,000 later I put her back on Fat Dog w/veggies at night and she went from 30 to 27 pounds and everyone is happy. Just FYI, she blew the ACLs chasing the same darn cat!!!!! She is eight years old and very active. She likes watermelon, honeydew mellon, and raw carrots. Nice treats! Hates apples.

My corgi LOVES it!

It's a little strange that my dog absolutely loves this food and it's the "diet" version of Natural Balance. I had been feeding him the sweet potato / fish formula

It's a little strange that my dog absolutely loves this food and it's the "diet" version of Natural Balance. I had been feeding him the sweet potato / fish formula and he likes that too, but this he goes crazy for. He actually chewed through the chewy.com box and through the dog food bag to get to it while I ran to the store really quick...........and that was while he had an abscessed tooth!!! Also, he seems to poop much less on this food than he did on the other. He could literally poop 4-5 times on a walk around the neighborhood on the regular food. On this he poops maybe twice. So, I'm not really sure what that means, but I'm enjoying less clean-up on our walks!!!

I have been dealing with Chewy.com for several months now. Service is excellent! Savings all kinds of money compared to buying at the local pet stores. Great personal service and quick delivery. Just received a personal Christmas postcard from Michelle in Florida. The Natural Balance Fat Dogs food knocked a few pounds off of our ten-year old beagle. He is short and always a little chubby. At his last check-up, the vet said that his weight was "ideal," not something he ever heard before. Delivery from Chewy is one day and it is nice for delivery to come to our front porch instead of hauling big bags of dog food home.

I love this food almost as much as my girl does. I have a 3 year old Great Pyrenees who is an amputee. Over the winter break, we both put on a few pounds. It is imperative that we both get back into shape and I have found this food to really help with her waistline...just wish it worked for me too. Being able to give her the same amount of kiddle with 1/2 the calories keep her happy and makes her think she is eating more. Fat Dog is a great product along with exercise to help my girl have ease with being able to help her balance and movement.

Good price for “specialty” food.

Hank has pancreatitis and has no more tummy troubles since eating this kibble. He thinks it is yummy as well!

Pembroke Corgi Loves

I have been with Chewy for over 4 years and love their service. I even order my dogs meds from them as well. As for this food, my corgi can be be a very picky eater and she loves this food. She has put on some “quarantine” weight over last year and I just can’t walk her as much since I just had hip replacement surgery. But in two weeks her harness is fitting loosely and her weight in her hips have gone down. So I will keep her on this food until she gets bored of it:)
