My folks have a pretty big yard, and a dog that loves to go pee on trees and other things in the lawn. Lately he has not been giving me much attention which kind of pissed me off, so I came up with something I know will really piss him off.
Basically I know all his favorite trees to mark, and I piss all over them from the ground to about 4 ft up in the air - saturating the bark. Then if there is any left over I circle the tree while making a spiral in the grass so he will instantly know when he gos sniffing around. Also I started peeing on his fenceline for his cage and he gives a look of disgust
