Dog Training is wonderful. I had a "bus stop" dog - a stray I literally picked up off the street - my first experience owning a dog - big chow mix. Stoopid as a post, horribly behaved, but oh so sweet. Took him to obedience class - that dog learned to sit, stay, heel, walk off leash, and came running when called.
It makes it so much easier on both the pet and the owner to train them.
