Who are the Bulldogs in hockey?

The term "Bulldogs" is used by several hockey teams. To tell you which one you're thinking of, I need more information.

Could you tell me:

* What league are they in? (NHL, AHL, OHL, etc.)

* What city or region are they from? (e.g., Canada, USA, Europe)

* Are they a current team, or a historical one?

Once I have this information, I can tell you which Bulldogs you're referring to!
