He is loyal and very protective to his owner.
Although he is quite fierce to strangers, but when you get along with him for a certain time, he'll likes you. For example, we have to change a new maid from time to time due to contract overdue but he is able to get along with new maids after few weeks and he likes them very much.
Despite he's a small size dog as compared to other breeds, he is also a very good guard dog, he'll alert family members when there's strangers knock on the door.
