Help for chuey

Hi my name is Brandon I'm starting a gofundme for my dog chuey yesterday my gate got opened due to high winds while I was at work , and when I return home I see the gate is open and my dog wasn't in the back about 5 minutes later my dog comes to the backyard limping so i take him to the vet he was shot 5 times by a bb gun how can people be so cruel he is the most loving dog I've ever owned ❤️
