Maltipoo puppies may come in small packages, but those early months bring plenty of growth, learning, and energy. The best puppy foods for Maltipoos come in formulas suited to small puppies, with calorie-dense nutrition and kibble that’s manageable for little mouths. Because small dogs can reach adulthood sooner than larger breeds, your Maltipoo’s feeding amounts and nutritional needs can change quickly. Your veterinarian can help you monitor their growth and determine when it’s time to transition to adult food.
