FAQs

How often should I feed my dog?

Puppies under 6 months need 3-4 meals daily. Adult dogs do well with 2 meals per day. Some owners prefer once daily feeding for adults.

Should I feed wet or dry food?

Both are nutritionally complete. Dry food is convenient and good for dental health. Wet food provides hydration. Many owners use a combination.

How do I transition to new food?

Gradually mix new food with old over 7-10 days, increasing the new food proportion daily. This prevents digestive upset.

Why is my dog always hungry?

Some dogs are food-motivated regardless of portion. If your dog maintains a healthy weight, the portions are likely correct. Consult your vet if concerned.

Do puppies need different amounts?

Yes, puppies need more food relative to their body weight due to rapid growth. Large breed puppies need controlled portions to prevent joint issues.
