Why Portion Size Matters
Maintaining a healthy weight is one of the best ways to extend your pet's life and improve their daily comfort. Even a few extra pounds on a small dog or cat can put significant stress on their joints and organs. If your pet is outside their ideal range, small daily adjustments to their calorie intake and consistent exercise can make a profound difference. Always consult your vet before making major dietary changes.
