FAQ
Should I choose grain-free?
Research says: Grain-free diets have been linked to dilated cardiomyopathy (DCM) in some dogs. Unless your dog has a diagnosed grain allergy, stick with grain-inclusive formulas. The FDA is still investigating the grain-free/DCM link.
What’s the best food for puppies?
Puppies need 28-30% protein and 18-20% fat for brain development. Hill’s Science Diet Puppy and Purina Pro Plan Puppy are consistently top-rated by veterinarians.
How often should I switch foods?
Transition slowly over 7-10 days: Day 1-2: 25% new food, Day 3-4: 50%, Day 5-6: 75%, Day 7+: 100% new food.
