We turned a walker dog i owned named amos loose a few years ago on a white footed boar that crossed the road in front of us right before dark 8:15-8:30 or so. Anyway 7:15 or so the next mornin he finally stopped it long enough to send cd's in and i'll be danged if it wasnt the same hog. Longest ive ever personally witnessed.
.
Damn how did the hog run
Honestly he just ran big circles in an old cutover like 1/2 to 2/3 a mile circles, he would bay for 10-15 minutes....sometimes a bit longer then break and run and bay again, amos was relatively new to the core pack of dogs we hunted at the time and to be 100% honest the hog would have been caught ALOT sooner BUT we couldn't get any of our other dogs to honor him......
I guess this isn't really what the op was asking about because it wasn't a solid non stop bay, but it is the longest ive ever been on the same hog..... we just never could get to him fast enough.
I know some people will say that the dogs that wouldn't honor him were culls And I can see why people would say that but to be honest we caught alotta hogs behund those dogs and once amos was around them for a while they honored him and he did them.....they were truely a "pack". They hunted and worked great together but werent quick to honor a strange dogs bay......we had alotta fun with those mutts!
