Help Juelz Recover from Pitbull Attack

Hello everyone, my son Juelz, 14 years old, was attacked by a pitbull. It bit him very badly on his back, foot, legs, and hand. He is currently in the hospital having to get another surgery. His insurance will cover but not cover all the expenses. My son is a really good kid, gets good grades, and is very good at basketball. He plans to go to the NBA after college, but if he doesn't get the proper care, he won't be able to. As for the dog, we don't know who it belongs to or where it lives or anything. I'm not asking for much; anything will do. I have to be off work to be here with him, and that's my only income, so I can only do so much. Please, if anyone can help us with anything, it will be greatly appreciated. Thank you, God bless.
