The Maltipoo is a small dog, commonly weighing between 5 and 15 pounds and standing 8 to 14 inches high at the shoulder. It comes in a wide variety of colors, including black, white, brown, peach, gray, and fawn. Many Maltipoos are bicolor, with a mix of white and another color on their bodies. Their noses can also be black or pink.Maltipoos shed little. They're considered good for allergy sufferers, but there's no such thing as a truly hypoallergenic dog.
