Many dog owners have this common problem. You’ve just gotten home from a long day at work and your large breed dog is beside himself to see you. He jumps up, pushing the bag of groceries out of your hand. Or you’re answering the door to your neighbor, and your too-friendly pet jumps up. Not only is this behavior considered rude, it can also be dangerous if your visitor is a child or elderly.
Any behavior that gets a positive reward is likely to be repeated. Never reward your dog for jumping up. Sometimes it’s obvious, but there are subtle triggers that can keep your dog jumping on people. If he’s met with petting or a warm welcome then he’s likely to continue the behavior. You need to let your dog know that you don’t like that and he won’t be getting anything pleasant until he’s calmly on all-fours.
