hey, I actually went looking for some info on the breed which my dog is, which is a catahoula leopard dog. something to read for those who are interested (don't worry, the annoying barking thing at the beginning stops after a few seconds)

here's an excerpt from that site:
Catahoula Leopards are extremely agile and athletic, territorial, protective of "their property". They are more primitive psychologically than most breeds and need consistent obedience reinforcement. The owner must understand the Alpha concept and stay in control at all times, but still be loving to the dog. Very loyal, loving, intelligent and independent... they really think for themselves
