On one of my Bulldogs I put a Sightmark Wolfhound 6x44 prismatic scope. Its a little bigger than I had thought it would be but I like it a lot. Very fast to use and plenty of magnification for my use. I've never posted a picture here but will give it a try, soon as I take some. My other Bulldog has no scope at this time. Still thinking about that one.
Not a bulldog owner, but yes the prism scopes are worth looking into, hey is that a pun
