This Week's Caption Came Quickly

When I first glanced at the illustration for this week's Caption Contest it seemed completely open ended.  A doctor talks to a dog.  He could just about be saying anything.  Then I looked a little harder, and I have to say that no other caption than the one I came up with, would now seem appropriate.  Look at the seem in the dog's neck.  It's a costume.  And then, sure enough, there are fleas scattered around. The obvious caption is as follows...

Okay, it's my blog so I'm going to indulge in pointing out what makes this caption work.
I think it's because it opens the door to so many other unanswered questions.  Such as...

Does the man inside have fleas, or it it just the dog-costume that does?
And if it's just the dog-costume that has the fleas, then why are the fleas attracted to it?
Is the dog-costume made from the hide of an actual dog?
And if not, could fleas be fooled into making a habitat of the costume's fabric?
But the over-riding question of course is,
Why doesn't he just take the dog-costume off and be done with the fleas?

Perhaps a more profound and disturbing question is,
Why is he wearing the dog-costume in the first place??
Is this man employed to wear this degrading costume?
Could catching fleas be a part of a Worker's Compensation claim?

You see what I mean?  The questions just keep rolling on out.
I had myself a good giggle. But my final question is,
What is it with that doctor's nose?
