For all their diminutive size, Maltese also seem, for the most part, to be without fear. Maltese seem relatively indifferent to creatures/objects larger than themselves, which makes them very easy to socialize with other dogs, and even cats. They are extremely lively and playful, and even as a Maltese ages, his/her energy level and playful demeanor remain fairly constant and does not diminish much.

Maltese do not require much physical exercise, although they should be walked daily to reduce problem behavior. They enjoy running and are more inclined to play games of chase, rather than play with toys.
