This is an Olde English Bulldogge as developed by David Leavitt of Pennsylvania, USA back in the early 1970s. This breed produces offspring like themselves and they have been doing this for years now. There are some crossbred dogs out there using the name "Olde Bulldogge" or "Olde English Bulldogge", but these are not "Dave approved" dogs. Dave approved dogs are purebred. This Olde English Bulldogge (above) is owned by Mike Walz and it is his foundation stud.
Here's a very nice Olde English Bulldogge owned by Arnoldo Diaz Jr. of Jersey City, New Jersey. It's about as nice a Bulldogge as I have seen in recent years. The last time I saw the dog (recently) I was with Dave Leavitt and we looked at it together. Dave liked it too.
