everyday
I cant see the point risking a dog for one shitty frosty night, when the next night could be gale force with sideways rain..
Work with the weather moons up go daytime, frosty go out with the stinkers, summer drink beer relax..
Just how i do it, sickener for me if I injure me dog with being to keen..
Done it ran my dog on hard ground in summer and frosty ground.. Got away with it on the frost could see the dog struggling turning and slowing up,caught a few boucing them off stone walls bigger feilds longer runs I would predict trouble I went home while I was a head.
