My neighbor had a friend come to visit him, and the friend brought his Pit Bull. So the dog jumped up to let me pet him better, and within seconds he developed an impressive knot. I didn’t touch him anywhere south of the shoulders, but there it was. No pink showing, just that bulge in his hairless sheath that left little to the imagination, and me fighting to keep my own composure. Don’t worry, I’m ethically opposed to most all promiscuity, including messing with another man’s dog. But he would be the perfect size and shape to take my ass. I need a “sweating bullets” smily to insert here.Last year, another neighbor had a big friendly mutt he kept in a fence. I would say hi to him when I went to check my mail, and he would stand up at the fence and show me his knot too. His wasn’t so big, but it was the same behavior. His owner decided to have some fun and acquired a hound mix in heat. The mutt banged her five times a day for ten days (and somehow I missed it every time. All I ever saw was the butt-to-butt part, so I didn’t learn a bleeping bit of technique). The owner sent the hound back to wherever she came from, and after that the mutt never showed me his knot again. Apparently after having had so much fun, he decided he was exclusively hetero.I’ve had other dogs greet me this way, with the knot without any physical contact. Maybe it’s just an overflow of excitement, or maybe it’s the standing posture. Is he thinking about humping my leg, but just not doing it? It’s probably just a normal dog behavior, but I’ve been noticing it more in recent years.Has anyone else noticed this?
