Awwww. This is the tiniest cutest Teacup Maltese I've ever seen. Now don't you wanna take this cute, precious puppy home. However, you may need to do more research and rethink if interesting in getting a Teacup Maltese puppy. According to an article in eHow by Rebecca Tait, the Teacup Maltese is known to suffer from certain behavioral problems, such as separation anxiety, suspiciousness when not socialized, housebreaking problems and frequent barking. These problems most often occur when the dog is left alone too much. Even just leaving the Maltese alone for a few hours could result in destructive chewing around your house. If you work out of the house all day, this dog is not recommended for you.
