Big dogs and little dogs.

Occasionally the big dogs need to burn off a little aggression.

The little dog stands by.

Add one more little-ish dog standing by.  Should she enter the ring?  Hmm...

The coaxing of little dog (hah, sounds like an indian name or something, Little Dog.)

Not surprisingly, a little too much for Little Dog.

That's more his speed, Little Dog safe in the arms of his momma.
