My 3 year old neutered male second generation wheaten/standard poodle mix is sweet, well behaved, gentle and affable. But when someone comes to the front door, he cannot control his excitement. It doesnt matter whether the person at the door is a total stranger or my mother, he jumps all over them in his exuberance. He often gets sent to his kennel as a punishment (which he hates but accepts). We could discourage his behavior with his electic collar but I am reluctant to use painful training techniques. Any ideas or insight you have would be appreciated.
