horse or 4 wheeler,bull whip,shock collar and use the command turn it around ....this works I run 10 hounds at a time at work horse back when i get road runners I chase them down use the whip and tell them turn it around after a few times I can ride down the road and dogs work side to side and if one lifts his head like he's gonna go i call his name and tell him turn it around
I got a 24yr ole horse thats loves to see a runner you give him his head and he'll roll one up
.....AND a big cattle guard works well also
