Well ear croping is not one at all over here so i dont have to see it. but if it is for breed standerd showing, to me, breed standerd is as they are not how they have been modifid (?sp).
all dogs and cuter naterally.

As for tail docking, i have never seen a BC with docked tail, to me they dont need to be docked.
if they are a well known happy breed then maybe it should be done but for working purposes no they need their tail for balance etc.

Sheep do need to be docked, as cleaning a flock of over 100 sheep and lambs is obserd, fly strike can kill a lamb.
As for cows well i would laugh it became comon, how stupid is that, they (mostly) are brung in for milking twice a day so it wouldnt be any trouble to wipe away the muck,

But people will do as they wish no matter what we think.
