Senior Dog Care: Keeping Your Aging Dog Happy and Healthy

When Is My Dog a Senior?

The age at which a dog is considered senior varies by size. Small breeds (under 20 lbs) are seniors around 10-12 years. Medium breeds (20-50 lbs) at 8-10 years. Large breeds (50-90 lbs) at 7-8 years. Giant breeds (90+ lbs) may be seniors as early as 5-6 years. Your vet can help determine when to transition to senior care.

Common Health Changes

Senior dogs commonly experience arthritis, cognitive decline, vision and hearing loss, dental disease, organ changes, and increased susceptibility to illness. Watch for signs like difficulty rising, confusion, increased thirst, changes in appetite, lumps or bumps, and behavioral changes. Twice-yearly vet visits with blood work help catch issues early.

Senior Dog Nutrition

Senior dogs typically need fewer calories (to prevent obesity) but higher-quality protein (to maintain muscle mass). Look for senior-formulated foods with added joint support (glucosamine, chondroitin), omega-3 fatty acids for brain health, and easily digestible ingredients. Discuss supplements with your veterinarian.

Quality of Life

Maintaining quality of life means adapting to your dog's changing needs. Provide orthopedic beds, ramps for stairs or cars, non-slip surfaces, and easy access to food and water. Continue gentle exercise to maintain mobility. Mental stimulation remains important — puzzle toys and short training sessions keep the brain active. In 2026, various mobility aids and therapies like acupuncture and hydrotherapy are widely available for senior dogs.
