Shot dog struggling to stay alive

While walking my dogs down our street, our friend and dog walker was confronted by an angry neighbor. This neighbor, who pulled a gun on our dog walker, turned the gun on our dogs and shot the father dog once and the dog ran. The walker ran after him. The other younger dog was only 18 months, he was shot 6 times. He died where he was shot. The older dog is now fighting for his life. Police are involved. Please help us
