Waiting for Daddy

For some reason, Ollie will only bark when the Hubby comes home... I mean, he barks whenever he hears a noise in the garage but once he finds out who it is, he stops...except if it's daddy. He'll continue to bark even after daddy enters the house.

It begins with what I call a "low-bark" which is sort of a "muff" sound...and then escalates from there.

We can't understand why he does this but it's funny to watch none-the-less. 

What? Daddy's coming home?

I'm listening but don't hear anything yet.

Maybe if I get closer to the door I'll hear him

Nope, still don't hear him

You're lying to me aren't you?

Why would you do that to me?
