back in the 90's I met a fella he was also opposed to bushy tails , our conversation were cut short due to tragic events his name was tattoo
sometimes late I met his good friend and mentor captain , cap went on about bushy tails for some time , he was convinced they were not purebred and garbage
I have not heard from captain in ages , I am not sure he is even alive today

long story short , I disagree with the above , I consider it in the same category as gunpowder for dogs
I can understand that a certain build is preferable , I can even understand how a screw tail may be linked in previous studies with hemivertebrae

but I never heard any of them linked to a bulldog being a bulldog
