And other breeds who don’t work and have never been docked also are prone to tail injuries as well...
Thing is though, breeds behave differently.
My collie is what you would expect for a collie, let her off leash and she will run far ahead, racing with abandon.
But compared to the working cockers I have seen she is very different, although she is probably just as active she shows it differently.
They (the cockers) quite literally race at break neck speed through absolutely everything, bouncing up and down, crashing through undergrowth in a way that collies just don’t.
Same for working Labradors, I have seen lots of active working Labradors but they don’t move in the same way.
A long tail isn’t at all practical for a working spaniel, as I said earlier, I don’t understand why they are not outcrossed with a natural bob tail like a Brittany or something and have the long tail bred out, it’s an absolute hinderance.
