If you want them to run deer put them on fresh tracks & encourage them to smell the tracks, follow them for a while & walk with them to make sure they stay straight. It' s good to get an older trail dog or beagle that won' t run off & leave them to help keep them straight on the deer. If they' ve got some hunt in their blood they' ll catch on pretty quick & leave the old dog behind.
I' ve got 2 5mo old beagle/walkers in the pen right now that will run with an older dog pretty well & take a track on their own for a while. If anybody wants them I' ll let them go cheap, got a gyp ready to have a litter any day now & need to make room.
