We had dogs for thirty years but decided when our last dog died that we wouldn't have another. The decision was for our benefit, in that neither of us is consistently fit enough to walk a dog, but also for the well being of the dog, who wouldn't get enough exercise. The OP's daughter doesn't seem to have thought through why she wants to have a dog. I think she needs to decide what her reasons are and whether she should even keep the dog.
But as for you OP - Just Say No!
