I've never been to a dog fight personally, I find it cruel. I do like chicken fighting though, even in chicken fighting, human aggressive birds are very undesirable because they're dangerous in the ring and usually get murdered
I like a good chicken fight too... Some roosters are just man fighters and they never make it to the pit. The last thing you want is a rooster to turn on you with a razor sharp blade on its leg.
One of my long time friend is big into rooster fighting and he spends more time with those birds than anything else.. Daily interaction and not being rough with them goes a long way
