I have never been a dog owner but dd2 (10) is dog crazy and I think it would be really beneficial for her to have a dog. However, I work part-time so am out all day 2 days a week and we also have two elderly cats. Could this possibly work? Are there any breeds that are happy to be at home alone for 8 hours? Do all breeds hate cats? I have told dd2 that it's not just about her wanting a dog, it's about whether a dog could be happy with us - she said "ask Mumsnet"
