Ugh, I'm so sorry you had this experience! It was the shelter's responsibility to either fess up that he needs to be an only dog family or that he wasn't actually tested with other kritters and children. Unfortunately I've seen this trend in the Seattle area with a few ultra condescending rescue organizations as I consider adopting my first furball myself. I realize they want to protect the animals but they can't chastise those that want the same good things for the animals!
