Health & Longevity Tips
• Schedule wellness exams at least once a year—twice for senior dogs.
• Keep dogs at a healthy weight; obesity can shave up to two years off their life.
• Dental care and regular grooming help prevent infections that impact lifespan.
• Provide mental enrichment (training, puzzle toys) to keep aging brains sharp.
• Tailor activity levels to size and life stage: giants age faster and need joint support earlier.
