Up in the clouds
I was always told to give the dog something to do immediately after any skirmish. It's the last thing you feel like doing but apparently it stops the dog immediately exiting the situation thinking 'well, I won that one, ya boo sucks, seeya next time, loser'...etc etc
So when my dog was launched on my another (he had been minding his own business) and my trainer had to wade in and pull them apart, he ordered us both to opposite ends of the car park to do herlwork, sit/down/stand etc etc.
And to keep your dog on a lead when out and about if you can't be sure of your control, or the dog's temperament.
I appreciate CC that both the two in training were deliberately off lead.
