My little guy was alone with his dead former owner for days. When we adopted him two weeks later, he was understandably upset. He is so much better two months later, but leaving him causes unbelievable pacing, crying, and barking for hours. Our vet explained there are four meds that he uses but he always starts with Trazadone. It has been great, not perfect, but it takes the edge off and lasts eight hours.
Good luck.
