How to Help Your Boxer Live Longer
-
Feed a quality, breed-appropriate diet
Boxers need 1200–1700 kcal/day. Avoid overfeeding — obesity can shorten a dog's life by 2+ years.
-
Exercise 60 minutes daily
Regular exercise maintains muscle mass, healthy weight, and cardiovascular health — all key longevity factors.
-
Keep teeth clean
Dental disease affects 80% of dogs by age 3. Brush teeth weekly or use dental chews to prevent bacteria reaching vital organs.
-
Regular vet check-ups
Annual exams catch problems early. After age 7, twice-yearly visits are recommended for most breeds.
-
Keep them mentally stimulated
Puzzle feeders, training, and new experiences reduce stress and keep the brain sharp into old age.
-
Maintain a healthy weight
Keep your Boxer in the 25–36 kg range. Even modest weight loss in overweight dogs significantly improves longevity.
