Yes they do, but it is very uncommon for a Boston Terrierto lock jaws with another dog or person. You will normally only encounter this if your trying to force something out of the dogs mouth ( Tennis ball, Rope etc. )
I have three Staffies, and they can get lock jaw, yes.
Yes, they do. Pit bulls/Staffordshire bull terriers do NOT though, that is a myth.
No, no dog does. There is no "locking mechanism" in any dog. Ever.
There are no dogs with jaws that actually lock. That is a myth. Some dogs such as Staffordshire & Pit Bull terriers do have extremely strong bites though and can be almost impossible to break, which is where the myth originated.
No, unlike pit bulls, rottweilers do not have locking jaws.
There are no such thing as Boston pug terriers but Boston terriers and pugs are both short haired.
Boston terriers are described to have a fur coat.
Boston.
Yes!
No dogs have "locking jaws", that is a myth.
Boston terriers are easy to train. But can be an itty bitty bit stubborn.
Boston Terriers were bread to be fighting dogs. When the breed originated they were bigger and tougher then the current typical Boston.
