Free: Contests & Raffles.
I'm obviously not a very good dog trainer, as I would have beat him a breath short of death with said shoe.
He pissed you left him home alone....all the chew toys in the world won't keep a dog from getting back at you when they wanted to go with Daddy....
When my last dog was a pup, he had the whole house all day, with another dog and one cat. He chewed all sorts of stuff including: Most all of my wife's left pump shoes....just the lefts...(I told my wife her right foot stinks...)....the dog ate a live lamp cord off. Ate it off. Still plugged in, copper wires sticking out nearly touching. Maybe a foot of wire missing. He chased the cat up a shelf, cat knocked the decorative glass top of our wedding cake off the shelf and onto the floor....ate half of the glass cake top. Ate half of the glass. Dog got my wallet one day....chewed every license and credit card into mungy. That dog crapped everything out and went on to live to 18 1/2 years...(after I beat the living crap out of him multiple times). Still, the coolest mutt around. God I miss him! Even though he peed on me in public.
