tail

Dog has managed to get happy tail for a second time and I'm now considering getting him docked as it's a medical reason, the vet however has said that they will only take a 1/3 of the tail off which a) still leaves a load of tail to potentially catch whilst he's out working b) looks bloody...

Could this be boar? The only thing that may give it away is the tail. If you think you know then please confirm. Regards Carl.
