Fight dog fighting.

How to Spot Signs of Dogfighting in Your Community

* An inordinate number of pit bulls being kept in one location, especially multiple dogs who are chained and seem unsocialized.
* Dogs with scars on their faces, front legs and stifle area (hind end and thighs).
* Dogfighting training equipment such as
o treadmills used to build dogs' endurance
o "break sticks" used to pry apart the jaws of dogs locked in battle
o tires or "springpoles" (usually a large spring with rope attached to either end) hanging from tree limbs
* Unusual foot traffic coming and going from a location at odd hours
