Thank you. That is very informative. I recently had a dog I rescued at my house for almost 2 weeks, and I have young cats that I've raised since birth, who had never seen a dog before. They were intensely curious, but also afraid of the big gray monster. (See http://www.sandramurquhart.com/3/post/2012/04/thou... for a pic)
Anyways, the dog was extremely friendly, and seemed to want to meet the cats...he was excited when he saw them, but in a good way, like he wanted to play with them. We kept him in our storage/laundry room, but they would sniff at the door on either side curiously. I just wondered how I'd ever introduce a dog into my family with these 4 cats that I have. We'd eventually like to get a dog. I did find the owner, btw, so the dog is back home now. Thanks for your response.
