Shih Tzus are generally from Japan!
The Shih Tzus nickname is "The lion dog".
Just like your question, both of the male shih tzus are the fathers.
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.
They love attention
they do but they are also very protective
Some do. I have one and he likes them.
Shih tzus can live with any dog as long as there not vicious, and are socialised properly.
Shih tzu's are adults when they are 2, just like any other dog.
Shih tzus weigh 9 to 16 lbs. I have two Shihtzus and they both weigh 14lbs.
