Kids and dogs:
- are messy eaters
- are loud at inconvenient times
- spread dirt on your clean floor
- run and play like hell
- sleep like rocks
- complain about being thrown into the bathtub
- complain about being taken off the bathtub
- silently wreck your things once left unmonitored
- are too cute to scold properly
- annoy the hell out of your neighbours
- and you still can't stop loving them. ♥
So yup, having one is perfect practice for the other! Although people typically do the opposite (use dogs to train for kids).
