Decided to take a whiz in the back yard last night,
because I can. The dogs were also out back, around the corner (I went out the side door of the garage), and when they heard me come out, started running over barking and growling. Pretty sure they thought I was an intruder, and it took me a few seconds to convince them of who I was. (good to know that they're defending the property)
Anyway, once they calmed down and I convinced the bigger one that he didn't need to stand right in front of me, I returned to the task. As I was walking back into the garage, I look back and he's sniffing around and PEEING RIGHT ON TOP OF MINE. Re-claiming the territory I guess.
