I tryed to slide down the slide, and I got stuck but my dog is here?

I'm stuck in a slide, cuz my little sister made me go down, and she started pulling my legs down. Now I'm stuck in the slide, using my iPhone right now, and who knows where she might be.
Parents won't pick up. I'm not calling the cops over something this stupid.
My dog is at the top, I guess he got away somehow. Most likely my little sisters doing. He is staring at me.
Is there any way to get out of this slide using my dog? I think I can but I don't know how to. If I can't use my dog, tell me how to get out! Please it kinda hurts.

Try to get the dog's leash and get it to pull… If you can call your sister get her to send the leash down from the top and pull…
