Another way I do my beagles ..and werks real good iffin yer by yerself...
is to first off, git ya pair knee-high of rubber boots, and I just spray em down w/ scent-away, includin the bottoms. If any of them dogs ever noticed my scent, they sure aint pay any bit of attention.
The other thing I do, esp w/ pups, is walk with em. Not only does that allow your scent to be there fer no other reason that yer there, but I can "hike" the dogs better that way, insteada hollerin clear across the state. I can watch what they do better that way too, and fix anythin that might be startin a new bad-habit.
Another REAL good plus about doin it this way..is that after the first few times of runnin a trail non-scented, then you start walkin near or with em, is that they learn not to start trailin just to be trailin. Fer instance, if my dogs are on a rabbit..I dern sure dont want em to start trailin a coon er a deer just because the scent trail is there. That also applies to yer trail. I lay them a seperate trail on purpose more times than not, just so i can watch/correct that trail-jumpin as we call it.
And if they do so happen to run that other trail I purposedly laid out fer em...OOPS...let em run...cause they headed fer a big ole U shaped pile of mousetraps
I reckon the most important thing to remember when doin it this way..is to be sure they're leadin, and not you...so all you have to do is stay to the side or behind em.
