Susan and I have two dogs, Soolin and Nori. On Saturday they were flipping out in the yard, so we went to check it out and discovered what appeared to be a stray dog sniffing noses with them through the ~4′ chainlink fence that surrounds the yard. We live on the corner and one of the streets is pretty busy, so we worried about the safety of the dog, and both of us tried to coax it into coming over, Susan from inside the fence and me by making my way onto the street from the other gate. The dog was skittish and ran away once, but then came back and to our great surprise it coiled itself up in a ball, made a huge standing leap onto the top of the gate, perched there for a moment like an owl, then lept into our yard. It was pretty amazing to see. This was not a large dog, standing a bit shorter than Soolin at the hips, but boy, it could leap like a kangaroo. Our best guess was it was on the prowl for a mate based on how he chased Nori around, but he lept right back over the fence when we tried to approach him to read his collar.
