i think your right as far as being a natral fighter he seems to love it. but it aint good . as far as being no good on quarry .he anilated two red ones in me back garden above ground . he had to bolts to ground witch came by way of accident really witch i was glad they bolted an he surfaced just behind them as i was alone with no collar an no gear.. so given the chance i think he would be good.to ground . its just that instinct to fight every dog he sees that the drama .iv started to accept it. but no it could cause nightmares if i ever get invited out with other dog men...
