Justice for our family dog

We are raising money to help pay vet bills and medicine and doctor appt for her every week she is getting X-rays and might need a surgery it’s gonna be a road ahead of us! We will update more of knowing! She’s our family she is also a support dog to my disabled mom and to my son who had anxiety! The kids are hurt and scared! My dad let her outside with him in our fenced yard also on a chained leash a cop walked up not saying who he is and no lights no nothing a normal family dog she is barked and he pulled his gun and shot her for no reason not only did he shoot her my dad was outside it could of been him! I had to put kids in bathroom cause of the gunshot and then the dog coming inside bleeding! She’s a loving dog she did no wrong she was in her fenced back yard on her leash she did no harm but to go where she heard noise and barked! Cop did wrong on not speaking and just pulling gun and shot and still did no talking!! We are hurt and emotional and down! Anything will help to get her on the road if recovering and justice for her!
