Thanks for all of the input on adding a second dog. I do think my current dog would be a great “mother”…she really seems like the caretaker sort but of course the cats do not want her love or caretaking! And she used to like to play with other dogs, but after a couple of bad experiences with other dogs out on walks, she’s shy now. I do think she would play with someone “safe.” We walk a lot, but she doesn’t get much play time. The slow introduction plan is great and yes, we would have to make sure that they get along before making it final. I do think though that once the new dog was in the home and the pack, she would welcome and care for it. We’ll see someday I hope!
