Why Dog Health Matters

Dogs depend on their owners for nearly every aspect of their well-being. Good health is not just about treating illnesses when they arise — it’s about prevention and daily care.

Key benefits of prioritizing your dog’s health:

  • Longer lifespan with fewer chronic illnesses

  • Improved quality of life through comfort and mobility

  • Reduced vet costs by preventing diseases early

  • Stronger bond between you and your pet

  • Adults: 2 meals per day with balanced nutrients

  • Seniors: Specialized diets for joint health and weight control

Avoid feeding dogs harmful foods like chocolate, grapes, onions, garlic, and anything containing xylitol.


2. Exercise: Keeping Your Dog Fit

Regular physical activity is critical for maintaining a dog’s physical and mental health.

Benefits of Exercise

Examples of Exercise:

  • Daily walks or hikes

  • Fetch games and agility training

  • Swimming or running (for high-energy breeds)

Note: Adjust exercise levels for senior dogs or those with medical conditions.


3. Preventive Veterinary Care

Routine vet check-ups play a vital role in maintaining dog health and catching potential issues early.

Recommended Veterinary Schedule
