The Maltese is a dog that belongs to the toy group and it generally weighs between four to six pounds. It is completely covered with long white hair from head to toe. Ideally there should be no other color on any part of their body although there is occasionally some yellow to beige coloring on their ears and tail. Maltese puppies are intelligent and energetic which is ideal for an apartment or condo dwellers. However, they don't do too well with other dogs or children - so this is something you might want to keep your eye on.
