I wonder if the little marking spritz is chemically different from the early morning bladder evacuation? Be neat if they were communicating something more then “I was here”. Sure seems like it. Sometimes my guy will study one for 3 solid minutes. Others he just ignores.
I think it is a way of communicating.
My female lab used to save up and spritz in about 15 different locations on her daily walks. She would also lick weeds or drag them through her mouth to leave saliva.
