My youngest (dd3 aged 12) is desperate for a dog. She has ASD and loves animals. We have a cat and 2 guinea pigs currently. She loves our cat but she is very different from a dog obviously.
I would also love a dog and oldest dd (18) is keen as well. However, dd2 (16) is very much against the idea. She's not keen on animals in general but can avoid our cat at home. She is scared of dogs and wouldn't feel comfortable at home.
I have suggested that we consider getting a dog when dd2 goes to university. I know that they don't properly leave home then and she will be home for long holidays etc but I thought it might seem like a good compromise.
