Do Cavaliers have any bad traits?
The only thing to be on the lookout for is their safety. Since Cavaliers are so non-aggressive and trusting they could easily be malled by a larger dog or injured by a small child. They would probably just stand or lie there and let it happen. They also love to chase butterflies, birds, and anything else they can find. It is imperative that they be on a leash when near a road or highway. Cavaliers live to please you. They are better trained using positive reinforcement instead of negative. Spanking a Cavalier will not work! They take it to heart and become very upset. It could also cause them to shy away from you.
