PLEASE HELP PITBULL ATTACK VICTIM

My name is Luis Cisneros. I'm 15 years old. It was Saturday night around 7pm, my friend and I were walking on palou between crisp rd and Griffith ave. We were on our way to another's friends house after we started to get a little closer to the basketball court we saw the pitbull just start charging down the hill. We thought it was friendly till it got closer and started growling. We started running but the pitbull grabbed the back of my thighs and I fell and scraped my face and it started to bite me on my arm on my legs it even tried to take my pinky off my hand. I just kept trying to cover my face. Due to the injuries I got on my legs, becoming a professional soccer player is out of the question. If I'm unable to cover the cost It was the worst experience I have ever had. I'm asking for people to please donate to help my mother cope with stress of all the medical bills.
