I have a bitch dog that is long range and won't stop till you catch her at the hog or cut her off somewhere. One tournament this year, hunted her non stop from dark Friday night (whatever time that was) till we got done at 930 on Saturday night, well over 24 hours on the ground. The last hog at 930 that night was over two miles from where she rolled out. I think we caught 25 in the tournament. The next day she acted like she had been on the chain all week and was ready to go again. My lacy dog is pretty much the same way, but she has had her foot broke a couple times and doesn't take day 2 quite as well.
My redbone is like that, she never gives up. She will run run and then run some more. If she is on something there is no calling her off it.
