Reply from Sundays for DogsJan 7, 2026
Hi!
Thank you so much for getting in touch with us — we’re thrilled that you’re considering Sundays for your pup! We’re proud to share that our USDA Beef, All-Natural Turkey, and All-Natural Chicken recipes are formulated to meet all AAFCO nutrient requirements for All Life Stages, which means they’re perfectly suited for puppies — including large breed puppies over 70 lbs.
We completely understand your concern and are happy to explain how we calculate your pup’s feeding recommendations.
Our initial feeding instructions are veterinarian-formulated, based on an algorithm commonly used in veterinary medicine. This takes into account your dog’s daily energy requirement (DER), which is the amount of calories they need each day based on their physical and lifestyle characteristics. To calculate this, we use key factors like neuter status, age, body weight, fitness level, and activity level.
It’s important to note that Sundays is more nutrient- and calorie-dense than most kibble, so you’ll likely feed a smaller volume than you’re used to. Because every dog and lifestyle is unique, we recommend monitoring your pup closely during the first few weeks. If you notice changes in weight or hunger levels, we’re here to help you fine-tune their daily portion. Most families can see if adjustments are needed within 2 to 4 weeks.
Our recommendations are always designed with your pup’s ideal body condition in mind. You can assess this at home or with your vet, either way, it’s the first step toward supporting their long-term health. As a starting point, we suggest increasing portions by up to 10%, reweighing every two weeks, and continuing to adjust until their weight stabilizes.
