Factors Affecting Longevity
While genetics play a huge role, lifestyle factors can significantly extend your dog's healthy years.
1. Weight Management
Studies show that dogs maintained at a lean body weight live up to 2.5 years longer than overweight dogs. Excess weight strains joints and vital organs.
2. Dental Health
Bacteria from periodontal disease can enter the bloodstream and damage the heart, liver, and kidneys. Daily brushing is the gold standard.
3. Spaying/Neutering
Statistically, fixed dogs tend to live longer due to the reduced risk of certain cancers and the elimination of reproductive complications.
