We always joke that our Labrador will end up breaking her tail at some point with how hard she whips it around.
I've come home today to find blood all on my walls/door - it's from the end of her tail (only found it as I can see the crusty dry blood on the end of it). She won't let me check it thoroughly enough to actually find a cut but it's definitely from there.
She's still wagging, can't see anything visible in the multiple times I've checked and the bleeding has stopped.
Do I let it heal on its own? I hear such horror stories about tails and their healing.
