If you arent lucky enough to get one of those mythical children who are angelic and never step a foot out of line; those animal harness leads ARE THE BEST INVENTION EVER!

Never had to use one on Ds1 but my Ds2 is a bolter. If he see's any opportunity to run, he will. Complete nightmare. The harness and lead make it so much easier to attach him to the pram so he can still be independent and walk but cant run off in the blink of an eye...................it acts kinda like a bungee cord and he just spring right back

Maybe see how your Ds goes before you buy one?
