I would if I was on my own, however my dogs have never ever fought amongst themselves(the bitches yes the dogs no). I have split up dogs fighting, but have always had another person to help.
The risk is,as happened to this young man, if you do intervene alone is serious injury &/or death !
If there are two or more calm people then it can be done with no one put at risk, but if there is only one person then sorry no.
I cannot understand why the owner of the dogs did sweet F.A.
Is it noteworthy that, thus far, nobody has come onto the thread to warn of serious problems in the pastoral breeds that makes them ticking time bombs?
