Do Lhasa apaso snore, and why, is it bad for them?

It isn't bad for them. Just as pugs and bulldogs snort many other dogs to as well, with snorting come SNORING. My lhasa apso snores really bad almost like a human. This is because of their short snouts and or their small noses. Don't worry if your lhasa apso snores, just make sure the snoring doesn't disturb YOUR sleep! :)
