I'm not saying it's wrong to have dogs and babies - if they had a dog now there wouldn't be a problem. I realise he grew up with dogs and has been around dogs, but has he ever had his own puppy as an adult? Raising a puppy is hard work and the puppy deserves the attention that raising one requires. I know I sound like a killjoy, but I also remember (just) how much time and attention a new baby requires. I feel it would be wholly unfair to have a new puppy at this time. In a year or so, fine, but having a new puppy at the same time as a new baby, the poor puppy has a high risk of ending up a rescue statistic.
