Walk in or Running Catch Dog ?

i run a dane x pit and hes the same way , he wont stay on fourwheeler he barks the whole time so i let him run . i use collar and garmin in summer and vest in winter . if your worried about him getting too banged up then you can run a light weight vest .... i use hard core vest they are light and tough ! if you dont want to use a vest then you can always get another rcd for back up . i use rcd and lead in but where i hunt the dogs never get farther than 800 to 900 yards and we hunt off fourwheelers so we can get there pretty quick if need be .
