There's no smoke without fire, IMO there's definitely Terrier in there. You'd have to be blind not to see it, of course certain strains that went over the pond had more Terrier blood in them whereas others had more Bulldog blood in them. Maybe the old Terriers added more than just speed and agility, gameness could have been a nice trait of theirs just like the Bulldog.

If you mean that by having 4 legs, a tail and a head they resemble a terrier then I agree but IMO that's where the similarity ends.
There's bull blood in most terriers if you go back f
