Do sheep listen?  I don’t know much about sheep, but nine months into dog ownership and I can tell you that they don’t always listen.  In fact, I’m convinced that my dog hears what I’m saying, comprehends what I want, but he still refuses to do what I say simply because he is unwilling.  I’m told that sheep don’t always listen either, but before I start in on a rant on white woolly animals, I should confess my own selective hearing issues.  Yes, I don’t listen at times too.
