I have a 6 1/2 year old pit bull. We've had him since he was 6 weeks old. He has tremendous training on him (I am a proud mom). The ONLY thing we can not break him of is attacking the windshield wipers!! If you turn on the wipers and he is in the car, he will be on your dash attacking the windshield! If he is outside the vehicle and you turn the wipers on, he will climb up your hood and tear the wipers off! Any suggestions on how to stop him?
