Buyer's Guide: How to Choose

Use this quick framework when you're deciding.

• Match the life stage. Pick puppy food for growing dogs, adult food for healthy grown pups, and senior recipes as they age.
• Check the kibble size. Look for "small," "mini," or "small bites" on the label for easier chewing.
• Consider activity and weight. Less active dogs may do better on a weight-management formula.
• Watch for sensitivities. If your dog vomits, has loose stools, or scratches often, try a sensitive-stomach recipe and monitor results.
• Read the feeding guide. Treat it as a starting point, then adjust based on your dog's body condition.
• Transition slowly. Mix new food with old over about a week to avoid stomach upset.

Try this approach: narrow your choices by life stage first, then by any special need like weight or digestion.
