We use a table for teaching Apport, brushing your dog, it also looks very similar to the agitation table so it will make it easier to transition the dog there later.
When the dog jumps on the table – mark and reinforce continuously. If the dog jumps off – lure him back onto it.
To teach the dog boundaries of the table – lure him around from the left to the right.
If you are working with a little puppy – keep the leash close so he would not fall off.
If the adult dogs falls off – do not make a big deal so as not to discourage him.
You can begin to work on eye contact and focus on the hand.
