Jumping is a behavior that can be traced back to our wolf brothers and is continued with current day dogs. Dogs jump for different reasons: a treat, a toy, a closer look but we are definitely sending a message. For me, I jump for joy. On the other hand, Sister does a ‘Me, Me’ jump. She wants the attention focused on her. “Ignore, Brother. Put the book down. Say hi to me first. Give me the treat,” you see what I mean.
Most of my jumping is exploration oriented. I have been known to get on the dining table but that is actually climbing because I had to use a chair. Bathtubs hold an attraction for me so I jump in them when given opportunity.
