we had a shizu dog for a long time, those things are so unhealthy i dont really feel keeping there species going is too ethical depending you ask, they make a grading nails on a chockboard noise when they start barking at 4am bc they cant see shit from there many cateracs and eye infections you'll regret buying one.
(our shizu passed away at 9 to 10 years old, they are not very hearty animals)
