Get + Prepositions Exercise 1

My dog, Rover, is so difficult to control. He is always getting the couch when I am not in the room. I always tell him to get of the furniture, but he just lies there looking at me. Last week, I was sitting on the couch with my girlfriend. He jumped up on the couch and tried to get us. I immediately yelled, "Get !" But, he just sat there, desperate for attention. When I eat dinner, he always gets the table and begs for food. Another problem is that I live next to a main road. He somehow gets of the house and gets the fence. I'm afraid he is going to get hurt. And last week, he got my closet and chewed up my shoes. I don't know how he got - I usually keep the door closed. I think I need to take him to an obedience school.
