Doesn't take a lot of observin' to notice that!
I've seen quite a few pooches that were into gettin' a bit of strange leg, if you know what I mean, (nudge, nudge).
I was trying to focus on Darwin’s own personal problem, which is why I suggested the problem started with a gang of dogs after a female in heat ~ but you could be right ~ somebody familiar with raising sheep could tell us what the collies do when we’re not watching eh!
