Aw, what’s the matter, pal? Can’t slink in and out of this fence like I can?
Gee, that’s just too bad… (heh, heh, heh)
From the uploader’s notes at YouTube: “Every evening a river otter comes to play with our daughter’s dog Rio. What was once an acquaintance on the other side of the fence has now become a friend who comes to play through the fence. It has been interesting to watch as their trust of each other has developed over the past several months.”
