Yes if they are pure bred
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 are generally from Japan!
The Shih Tzus nickname is "The lion dog".
Some shih-tzus have cherry eyes. My shih tzu has one.
Shih Tzus are primarily used as Companion Dogs.
Common skin problems that Shih Tzus may experience include black spots, also known as hyperpigmentation, as well as issues like dry skin, allergies, and hot spots. Regular grooming and proper care can help prevent and manage these skin problems in Shih Tzus.
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.
