Personally i'm against cropping or tail docking..it is of no benefit to todays dogs at all. I'm pretty sure its illegal here (i'd have to check)

My fella has floppy ears, but let me say people are scared of him. I take him for a walk and most people will cross to the other side of the road, or as far from him as possible. He makes no move toward them but he stares, i mean very very intently at anyone coming toward him and it is un-nerving obviously. His sheer size (50kg+) too is very offputting.

I don't find dogs with up ears or floppy ears any less intimidating, the thing i look at when approaching a dog is their eyes and hackles *LOL* I treat all strange dogs with respect.
