Quick Answers

Why do small dogs need special food?

Small dogs have faster metabolic rates and require more energy per pound of body weight than larger dogs. Their smaller mouths also require bite-sized kibble to prevent choking and ease chewing.

How often should I feed my small dog?

Many manufacturers and veterinarians recommend dividing your small dog's daily food portion into 2 to 4 equal meals per day to support steady energy levels and digestion.

Can I feed my small dog standard adult kibble?

While standard kibble may meet basic nutritional requirements, the pieces are often too large for small breeds to chew comfortably, and the formula may lack the calorie and nutrient density they require.
