Despite lower calorie needs, senior dogs still need adequate protein to maintain muscle mass.

Frequently Asked Questions
When should I switch my dog to senior food?
Start transitioning around 7 years for most dogs, but this varies by size and breed. Watch for signs like decreased activity, weight changes, or stiffness.

No—puppy food is too high in calories and protein for senior dogs. Senior dogs need fewer calories but still adequate protein for muscle maintenance.
How much should I feed my senior dog?
Senior dogs typically need 20-30% fewer calories than adults. Follow package guidelines and adjust based on your dog's weight and activity level.
