How To Deal With Bad Behavior
Don't let the regal profile fool you. This little guy was rescued off the streets of Los Angeles and promptly started lunging at anyone and any dog that came within biting distance.

Other dogs, with less offensive behavior, may be allowed to get away with their antics, but that's a mistake. There's no reason to put up with anything that causes stress or destruction.

You also need to use a collar that the dog can't slip out of. A martingale is the standard. Mendota makes a leash with a martingale collar attached.
