Champ is a happy-go-lucky Labrador Retriever who was driving his owner crazy. My client, a busy building company executive, was tired of living with the problems, but didn't have time to attend classes. Champ pulled on the leash until he literally choked, ate off the kitchen counters, and was a habitual runaway.
Moreover, he charged through any open door, and would leap into any open car, acting wild inside the moving vehicle, scratching his owner's leather interior, and creating a road hazard.
Ten days after arriving at our home training faciilty, Champ went home. His owner cringed while opening the car door, expecting Champ to fly in as usual, and jump into the front seat as always. He was very happily surpised when Champ wagged his tail, and waited for permission to enter the car.
After living with his dog for a week at home, Champ's dad called me to report the dog was better than he ever expected. I can immodestly report that his exact words were, "You're a miracle worker."
