I put my dog on a surf board and drug it behind my car and it was like he was street surfing but when I took a sharp turn the idiot dog flew off and hit a parked car. He made a huge dent to the other car and when I went back to check out the scene I got nervous and took off really fast. I felt like I hit something and looked back to see my dog rolling in the street. I was too scared to go back for him....Do you think he is ok?
