I've been taking my friend's dog Bella for walks when I get a spare hour during the week. It's been nice. I've always wanted to get a dog but can't see us getting one any time soon as we'll have the new baby soon enough.
Once thing that could change our mind though is the fact that it's more than likely that we'll be working from home a lot more in future so being able to take the dog out for regular walks becomes a lot easier. Plus they won't be left home alone all day.
