What about DINKWAD? Dual Income No Kids With A Dog - very popular place to be!
For reference both 31, we were waiting til we had a house (coming up to two years of owning now...) and was a case of "let's see what happens first - kid or dog come summer" - the dog won
We both want kids, at least we certainly did, but as others have eluded to the cost of living is silly, and the dog takes up a surprising amount of effort (read: surprising how much more effort than we expected, which was already quite a lot) so we've slowly drifted to no longer that fussed... Just wished we'd come to that conclusion before buying a house with kids in mind, could have gotten so much more land for the dog otherwise!
