Catch dogs that never miss

My buddies and I have a family of dogs that produce the style you are talking about. My old Vegas dog was one of them. He was between 85-90 lbs with a lot of leg. NEVER said a word in the box, on the wheeler, or at in the brush. He walked with me off leash and didn't go until I told him to. When I sent him it wasn't wide open. He would pick his path and be just as quiet and easy not blow through the briars. He would catch either ear, I don't think he decided which one until he laid eyes on the hog and then took the most convenient one. Those last 3,4 or 5 steps he would catch a couple gears. We were talking the other day and none of us could remember a hog that we didn't catch that we sent him to, very accurate. If it broke before he got there, he almost always caught it still. If he didn't have it in about 60-70 yards he came back. I have watched him run off and leave some 45-50 pound dogs to hogs in the wide open. When he ran one down, he would bite it in the butt to stop it then as soon as it did he went to the ear. He was also smart enough to reason. He didn't run straight to a hog that was on the run if it was running across us. He took the angle on them. I could tell him caught hog and make him back up without having to tie him back. He would sit there and watch quiet and be ready to go to the next one when you were done. When he caught it was deep and what I mean by deep was he had the base of the ear as far back in his jaw as he could get it. There was no chewing or regripping. He had as much stamina as needed too. He was good for as many hogs as you needed him for. I have a puppy out of him now that I think is going to be just like him. I'm real excited about her, I can already make her come back to me after he has started to a hog already and she is real quiet. Almost scared to take a chance on getting her killed. She caught a couple times when she was 4.5 - 5 months old. She's about seven months old now so it will be a while before she goes to the woods and she isn't getting to catch anything until her teeth are mature.
