I had a friend once, who had gone through a divorce, and she and her ex actually did share custody of their two dogs, sort of like parents do with their skin kids. For them, it worked well, but I can imagine that it would be tough. When I divorced, we had our Lab, Chuck, and Mimi, our beautiful cat. I don't think we ever even discussed "sharing" either of them. We were lucky, I guess, that we just sort of knew that Chuck needed to stay with him at the house, with the fenced yard, and Mimi would come to the apartment with Helen and me. Both of them thrived, so it was obviously the right decision. But I was always so happy to see that sweet face when I would go pick up Helen. Chuck lived to the ripe old age of 15. And you all know that Mimi is still thriving at 13 years old!
