pritty much all performance stuff to him but what drive the dog has,yet definatly a kinder disposision to kids than a lot of pits that ive seen and wouldnt trust.good guard and protect dog but he is very agressive in work very hard to get off a better trainer would have probebly got him to come off better than me.he looks heavey but is very fast suprisingly would like to see what would be produced to a grey,
