What Happens to Dogs Nutritionally as They Age
Most 'senior formula' dog foods are simply lower-calorie versions of the same processed kibble. They address one aspect of aging (weight management) while ignoring the nutritional changes that matter most.
Muscle Loss
Senior dogs lose muscle mass faster.
After age 7, dogs begin to lose muscle mass at an accelerating rate. High-quality, bioavailable protein is the most important nutritional intervention but most senior kibbles reduce protein to reduce calories.
Joint and Mobility Decline
Joints need more support, not less.
Aging joints benefit from anti-inflammatory nutrition: omega-3 fatty acids, antioxidants, and real food ingredients that support the body's natural repair processes. Synthetic additives can contribute to systemic inflammation.
Immune System Changes
The immune system needs real nutrition to function.
As dogs age, their immune systems become less efficient. Real food ingredients, particularly antioxidant-rich fruits and vegetables, provide the micronutrients that support immune function in ways synthetic vitamin blends cannot replicate.
What Sundays Provides That Senior Kibble Doesn't
High Protein for Muscle Maintenance
Sundays recipes are 83-91% real, meat protein significantly higher than most senior kibbles. High-quality protein is the most important nutritional factor for maintaining muscle mass in aging dogs.
Nothing that stresses aging organs.
Aging dogs' livers and kidneys are less efficient at processing synthetic additives. Sundays contains no synthetic preservatives, artificial colors, or artificial flavors, just real ingredients their bodies recognize.
Real Antioxidants from Real Food
Sundays includes real antioxidant-rich ingredients that support immune function and cellular health in aging dogs.

A Vet's Perspective on Senior Dog Nutrition
I see senior dogs every week in my practice. The most common mistake I see their owners make is assuming that a 'senior formula' kibble is doing the job. Most senior formulas are simply lower-calorie versions of the same processed food. They don't address the real nutritional changes that matter as dogs age.
What senior dogs actually need is higher-quality protein (not less protein), real antioxidants from real food sources, and the absence of synthetic additives that stress aging organs. That's what Sundays provides.

FAQs
FAQs
Is Sundays appropriate for senior dogs?
Yes. Sundays is formulated for all life stages and meets AAFCO nutritional standards. The high protein content (83-91% real meat) is particularly beneficial for senior dogs, who need high-quality protein to maintain muscle mass as they age.
My dog is already on a senior formula. Why should I switch?
Most senior formulas are lower-calorie versions of standard kibble. They reduce protein to reduce calories, which is the opposite of what aging dogs need for muscle maintenance. Sundays provides high-quality protein from real, named meat sources, with no synthetic additives that stress aging organs.
Is Sundays good for dogs with joint issues?
Sundays contains no synthetic additives that contribute to systemic inflammation, and includes real antioxidant-rich ingredients that support the body's natural anti-inflammatory processes. For dogs with diagnosed joint conditions, consult your vet about whether Sundays is appropriate alongside any prescribed treatment.
How do I transition my senior dog to Sundays?
We recommend a slower transition for senior dogs: 10-14 days, starting with 25% Sundays mixed with 75% of their current food, and gradually increasing the Sundays ratio. Senior dogs' digestive systems can be more sensitive to dietary changes.
What if my dog doesn't like it?
We offer a 14-Day Money Back Guarantee. If your dog doesn't love Sundays, contact us and we'll refund your first box in full.
