hmmm sensetive subject you got there i know many sports guys that will rip my head off if i'll tell that there dogs useless in PP LOL i think that you have difference and a big one. first of all you can find some good sports dog that are pretty crappy as a PP dogs and you can find some amazing PP dogs that can barly pass the schh each thing ask for a different kind of a dog, each side look for somting els and training in a different way. take us for exsample: at first we started by working our dogs for sports, very fast we learned that good sport grades and titles doesn't say much or even nothing about the dog, you can find dogs with high titles that you can't stop thinking how the hell they got so far and you can see some great producers and workers that just can't take the title because they very hard to controll as a working dog but they also amazing in drives so you can't say the're crap. so i won't be killed in the night by sports lovers i say that you can also find some reall kick ass dogs in sports but for me the sport himself deosn't say much about the dog except ofcourse the KNPV here i have alot of respect to the greatest sport ever that succsessfully keep producing the best security kind working dogs for police, military and etc :lol: you can't say what's better and what's worse because each trainer or breeder look for somting els, uses different kind of dog ( bloodlines ) to get to what he needs
