I'm attempting to teach Julio to target chairs, but can't get him to target the actual chair. He knows to target my hand, but won't target the chair unless that hand is on the chair. Baxter, who was watching me, has figured out what the clicker means, and seems to respond well. He's now figured out targeting chairs somewhat, and was "proffering paws" for clicks. Which dog am I training?
