Why Most Weight-Management Foods Don't Work
Cutting protein to cut calories is the wrong trade-off.
Animal proteins naturally contain complete, highly bioavailable amino acid profiles without needing to be engineered together from multiple plant sources or synthetic additives. When weight-management foods reduce protein and add fillers, dogs feel less satisfied and are more likely to beg, overeat, or gain weight back.
WRONG Protein, High Carbs
Corn, wheat, and soy are the problem, not the solution.
Fillers Add Empty Calories
High-carbohydrate fillers are a primary driver of weight gain in dogs. They provide calories without nutrition, spike blood sugar, and contribute to fat storage. Most weight-management kibbles still contain them.
What you don't see on the label can still cause problems.
Synthetic Additives
Synthetic preservatives and artificial additives can contribute to systemic inflammation, which is linked to weight gain and difficulty losing weight in dogs.
80-91% Animal Protein. No Fillers. Real Satisfaction.
Sundays for Dogs takes a fundamentally different approach to weight management: instead of cutting protein and adding fillers, we start with 83-91% real meat protein and eliminate the filler carbohydrates that drive weight gain.
Dogs feel full because they're actually nourished.
At 80-91% real animal protein, Sundays provides the high-protein nutrition that keeps dogs satisfied between meals without the hunger that leads to begging and overeating.
No corn, wheat, or soy.
Sundays contains no filler carbohydrates. The carbohydrates that are present come from whole grains (oats, quinoa) and vegetables not processed fillers that spike blood sugar and contribute to fat storage.
Real food is easier to portion correctly.
Sundays' custom meal plans are calibrated to your dog's weight, age, and activity level. You get the right amount for your dog's specific needs, not a generic serving size from a bag.

We’ve had our dog Joey on Sundays for a month and we have seen so many positive changes. We started with frozen food and noticed he started losing weight and realized he wasn’t getting enough of what he was eating. Now he has healthier stools, energy, coat and back to looking himself.

My Lala loves her beef recipe. She’s lost some weight and she’s got lots of energy.
James G.
Parent of Lala
I never believed a dog food could get rid of bad breath, but it did! And it also helped my dog go back to and maintain a healthy weight and no longer have an upset stomach. What is more amazing is that my senior dog seems five years younger and full of energy again. Thank you.

A Vet's Approach to Dog Weight Management
A Vet's Approach to Dog Weight Management
Obesity is the most common preventable condition, and the standard advice for fixing it usually makes things worse. In my years practicing veterinary medicine, I would hear over and over again from well-meaning dog parents, "We already switched him to the low calorie food." They say it with relief, like the problem's handled. I understand why. It's the advice printed right there on the bag, and it's what most of us grew up doing with our own diets too.
But most "light" or "weight management" kibbles solve the wrong problem. They're formulated to hit a lower calorie count on paper, and the cheapest way to do that is to cut the most expensive ingredient (protein) and bulk the recipe back up with fiber and filler carbohydrates. The bag now says "light." The label now says "fewer calories." The dog is still hungry, and the weight often doesn't move.

“Serving a low-quality, filler-heavy food is a losing battle. You can serve the 'correct' amount and still leave your dog hungry and undernourished in the ways that matter. High-quality protein and real ingredients served in the right amount for your dog's specific needs is the combination that addresses the actual cause of canine obesity, instead of just moving numbers around on a nutrition label."

Questions About Sundays and Weight Management.
IS SUNDAYS APPROPRIATE FOR OVERWEIGHT DOGS?
Yes. Sundays' high protein content (83-91% real meat) supports muscle maintenance during weight loss, and the absence of filler carbohydrates removes a primary driver of weight gain. Our custom meal plans are calibrated to your dog's specific weight and activity level to ensure the right portion size.
HOW DOES SUNDAYS HELP WITH WEIGHT MANAGEMENT IF IT'S NOT A 'LIGHT' FORMULA?
Most light formulas cut calories by cutting protein and adding filler carbohydrates which leaves dogs hungry and doesn't address the root cause of weight gain. Sundays focuses on high-quality protein (which is satiating) and eliminates filler carbohydrates (which drive fat storage). The result is a food that supports healthy weight without leaving dogs unsatisfied.
HOW DO I KNOW HOW MUCH TO FEED MY OVERWEIGHT DOG?
We recommend a 7-day transition: start by mixing 25% Sundays with 75% of your dog's current food, and gradually increase the Sundays ratio over the week. A slower transition (10-14 days) is recommended for dogs with sensitive stomachs or skin conditions.
HOW DO I TRANSITION MY DOG TO SUNDAYS?
We recommend a 7-day transition: start by mixing 25% Sundays with 75% of your dog's current food, and gradually increase the Sundays ratio over the week.
WHAT IF MY DOG DOESN'T IMPROVE?
We recommend a 7-day transition: start by mixing 25% Sundays with 75% of your dog's current food, and gradually increase the Sundays ratio over the week. For very picky dogs, a slower transition (10-14 days) can also work well.
