Benny’s amputation surgery

Please help! 
Earlier today Kaitlynn and I were taking Benny on a walk. As we were walking down the street we walked passed a house with two people standing outside and their door was opened. A pit bull ran out of their house and started to smell Benny pretty civilly. Unprovoked, their dog got a hold of Benny’s neck and wouldn’t let go for about 5 minutes. The owners had to physically punch their dog repeatedly to get Benny out of his mouth. When the dog finally let go, Benny got away. He is fortunately alive but is not okay. Benny has to have his front leg amputated and his neck lacerations surgically repaired. The cost of this is not going to be easy for someone like me. So anything at all will help please ❤️ Benny is the sweetest boy and I’m so sorry for his journey ahead and trying figure out how to live life with 3 legs. Please help me get my boy better.
