Shih Tzus are generally from Japan!
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.
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.
Just like your question, both of the male shih tzus are the fathers.
Why Yes They Do
