Carly is an escape artist, a problem solver.
She can climb fences, as she demonstrated three times last weekend in Michigan.
She can open doors, as she demonstrates every morning as soon as Lisa leaves for school. Granted, the door doesn't latch (it has shrunk because of the winter cold dryness), but she manages to get past the blockades Lisa puts there too.
Today, she chewed off her training collar, somehow. The nose strap is supposed to be loose enough to go almost to the end of the nose, so the dog can still eat, bark, breathe, all that. We had painstakingly fitted it properly, but apparently Carly managed to get it in her mouth tonight and chewed the strap until she was free.
What a pisser. This thing really helps us keep her under control while we're walking -- she doesn't pull hard, she doesn't hunker down to sniff every damn thing she smells, she barks less (although she still does if the people are intimidating), and is generally better behaved. She doesn't like it, but it's much more comfortable than a muzzle, and much more useful in training. So now it's drop twenty or twenty-five clams on a new one, or sew the strap back together on this one.
Smart dogs are a mixed blessing. It's a good thing she's cute.
