Requesting to come in politely?

[Sandy]

Toby has an awful habit of LAUNCHING himself at the patio door when he wants in. When I say "off" he gets off. I never open the door when he "up", only when he's not on the door anymore. I do not know how to stop this! At some point I'm afraid he'll just break right through the glass! The only though I have it to put up a little wooden fence of some type (moveable) that will prevent him from jumping on the door. Any thoughts? He's not a little boy (about 70 pounds), so he needs to stop!

My Toby also just stands at the door when he wants to go out. I am having some early success with the hand signal to sit. Fingers are crossed. Our glass doors are scratched as well....

A yip is a good description.
