Hi there!
I believe there is a Club.
This may be old information, but you could try contacting Ms. Girling on (08)9378-2269.
If you don't have any luck there, try contacting "DogsWest" on (08)9455-1188.
(Note that it will be called the British Bulldog Club/Association.)
You may also meet other Bulldog owners here: LINKY!
Thank you. I'll have a look.
