yeah it is highly possible . i would start my pups running drags at three months [ hound/ cat crosses ] and by four months old they would be pretty good at it . i have a time or two been working them on a drag in the swamp behind the farm and have them leave the drag trail and bay up pigs i didn't know was in there lol . at first you run in there gonna try and catch them for trashing to realize it's a pig lol but like i said working them alot and often . it is not an unreal or unbelievable idea to me . hell me an my ol walker gyp was tearing them coons butts up when she was 6 months old in the 80's but we was in the woods every day for 2 months prior . but that don't meen there hog dogs at that age it just meens they got it down and will eat my feed till time to really hunt them and prove their worth . big differance in a dog knowing what to do and being able or mature enough to do it .
ill agree with u on this one its not impossible at all, yeah 700 yrds is a long way for a 4 mo old pup, but I have had and have seen pups find hogs at 5/6 mo old. Have to think that a 4 mo old pup is 4 mo right up to a sec before he turns 5 months lol. I have to dogs that winded and would bark of the Wheeler when thay was 6 mo old, so I'm gonna say it could happen.
