In my own opinion i beleive the the best dog is an all around dog no doubt. That saying it jack stated that different lines throw differnt traits and performcance yes and that " Next comes (4) the subject of what bloodlines to use. This really is a personal consideration, but either way (if you want to succeed) you need to go with a high-percentage bloodline. Doesn’t necessarily have to be a high-percentage “game” bloodline, but the dogs should definitely win more than they lose, when the money’s on the line. The rest is a matter of personal style.

Do you like wide-open barnstormers, or methodical, slick dismantlers? If you like barnstormers, the Eli/Nigerino type dogs would be a consideration. Many Red Boy/Jocko dogs are like this, and many Boyles-bred dogs are too. The bonus of these kinds of dogs is their style makes them win early – which means you can show them more often, because they don’t take as long to win and (hence) don’t take as much abuse. Their liability, though, is some tend not to be as game ... if they are in there with a good one and are forced to go the long haul ... and thus you will get more curs out of them. Many people don’t mind going through a bunch of curs to get their ace, because they know he will be a money-maker …


However, if you like dogs that tend to be distance athletes, who save themselves for later and come on strong in the end to pull out the win, then I would recommend the Hollingsworth and CH Butkus crosses as well as the CH Bullshit/White dogs. Pure Red Boy dogs tend to be like this also, but they also tend to be very stupid. The bonus of distance athletes is that, as a line, they tend to be game more consistently than other lines, which means you don’t have to cull as many animals. The liability of these kinds of dog is they tend to take longer to win (and thus more abuse), which means they don’t win as many shows, per dog, as more barnstormy dogs do (on the average) ... but in the trenches they are more dependable.
