YES YES YES !!!! We walk her off-leash in the forest in my backyard ( thank heavens for the forest, cuz otherwise she'd NEVER get enough excersize ) So logically, she runs through who-knows-what in there,i stay on a trail i made through there, but she runs through the bush, there is much mud and lots of deer ( and any other animal ) poop in there.( Tell the deer to scoop it ( lol ) )
