I am a senior mom living alone. I have a small, well-trained, hypoallergenic, child loving dog who is my frequent companion, indeed almost a best friend. My grown, married daughter will not let my dog in her house, gives no reason except to say "it's about boundaries and I have to accept hers without explanation." When we sit inside, the dog is alone and crying outside. My grandchildren love the dog and don't understand the rule but abide by it. I feel very hurt. I don't want to leave the dog at home alone and I don't want to give up visiting my grandchildren. My daughter refuses to talk about it. Please advise.
