[quote1324109580=Crnosrce1] Alan, Ofcourse DA can be trained up or trained down in a dog. Mel is a very knowledgable and skilled trainer who will be able to tackle those issues when they arise. It is an inherint trait, it is also due to nature/nuture. [/quote1324109580] Thanks Mike, I'll look out for the DA. At THIS point my boy Butch loves EVERYBODY but NOW I've resorted to keeping him from being friendly to MOST people and dogs due to the fact that I socialized him THOROUGHLY from abput 2 months and now I want him to try to detect friend versus foe. So at this point nurture has been taken care of, I don't know about nature. I do know he has NO fear of being in crowded places or around other dogs he'd rather PLAY than fight at THIS point so I'll keep my eyes open.
