That is too cool! I'm super envious! Bullie refused to do the handshake. For some reason, she won't do much of anything that requires lifting her front leg - like going inside the van or the bath tub or climbing stairs. She would go on the old couch, but she doesn't do it anymore with our new couch. I think her hips are too weak to support her chest without her paws firmly on the ground.
Great job, Watson! Lola will only high five/shake if she has a toy in her mouth. Otherwise, she only wants to mouth your hands. I'll have to try carrots!
