Thank you, boo3792! Henry is a pretty smart boy...he picks up stuff so quickly, and understands some hand signals and a tiny bit of Spanish, which my mom and I are semi fluent in. Besides all his English commands, he knows ven aqui (come here), para(da) (stop it) and abajo (down). Plus I use the German word for heel, ferse. I pronounce it foose lol. Oh, and he recalls to a special whistle.
