The Morkie blends the personalities of two interesting Toy Breeds. While the Yorkie is a confident attention magnet, the Maltese is an ideal lap dog. The Yorkie and Maltese can be good with other family pets when socialized early and often, but will need to be watched over carefully when around strange dogs to keep from getting into disagreements with much larger breeds.
Neither the Yorkshire nor the Maltese seems to realize they are a small dog, which will probably translate to the Morkie as well. These dogs are watchdog, however, so a home with very young children will require supervision to assure that the toy-sized Morkie is not accidentally injured by rough play.
