Shih Tzus are generally from Japan!
Yes, Shih Tzus get along fine with other dogs as I have one and it gets along with alot of other dogs.
The Shih Tzus nickname is "The lion dog".
Shih Tzus are primarily used as Companion Dogs.
Some shih-tzus have cherry eyes. My shih tzu has one.
Black Shih Tzus are not considered "Rare" but there not as common as the black and white Shih Tzus. I recommend this breed to anyone.
Yes, they do. I dog-sit for my grandmother's shih tzu or she dog sits my Yorkie from time to time. They get along great!
Shih tzus can live with any dog as long as there not vicious, and are socialised properly.
Shih tzus weigh 9 to 16 lbs. I have two Shihtzus and they both weigh 14lbs.
