Any dog can get the lockjaw condition, which is a condition that develops from wounds that do not heal properly and develop bacterial contamination that gives dogs lockjaw. There is also a myth that some dog breeds have a locking jaw, but this is false, as there are not any dog breeds that have locking jaws.

As for the lockjaw condition, outdoor dogs are the most likely dogs to get the condition, because they are often left alone and may not have owners who will properly clean and care for any wounds they might sustain. Veterinarians can diagnose and treat lockjaw, by performing laboratory tests including culture tests and a physical examination.
