I promise my dogs aren't ferocious...

the bunnies were just taunting them...
especially the pink one...

and for anyone that thinks that Chaco is a poor picked on younger brother...
notice the migration of the bone;
first safely between Libby's paws...

Libby: Wait a second, where did that go?

Chaco: Chomp Chomp Chomp
Libby: *Sigh*
