Google "how to break up a dog fight" and the first hit I got was this, which I recommend. It includes many photos of dog bite wounds, to remind us of what can happen if we react incorrectly to this very dangerous situation:
http://leerburg.com/dogfight.htmAn excerpt from Mr. Leerburg's website {without permission, hope he doesn't mind}:
"I will start with a warning. Unless you have a lot
of experience do not try and break up a dog fight by yourself.
Never
step
in the middle of two loving pets and try and grab them by the
collar
to stop a dog fight. If you try this, the chances of you being
badly
bitten
are extremely high. People don't understand that 2 animals in
the middle
of a fight are in survival drive. If they see you at all, they
don't
look
at you as their loving owner. When you charge in and grab them
they either
react out of a fight reflex and bite, or they see you as
another aggressor.
When they are in fight or flight mode they will bite you. You
can take
that to the bank."
Don't think your corgi isn't dangerous just because it's a small dog. I grew up with a dachshund, not bigger than a corgi, which bit my uncle quite severely on the hand when he was trying to extricate it from a leghold trap. A panicked dog is a dangerous animal.
It may be important to distinguish a real dog fight/attack from a mere argument, which might look ferocious but is just a coupla dogs harmlessly working out a disagreement with no damage intended:
http://blacksheepcardigans.com/ruff/?p=4000It would be a good idea to be able to recognize the body language that might signal a fight or attack, and know what to do. I've no clue.
This might be a good FAQ topic. Any experts, kindly hold forth?
