If you’ve just brought a puppy home, a free-standing gate is a real mutts-purchase, and the best way to make sure bedrooms, staircases, and other danger zones are off-limits. They’re also great when you have house guests who just aren’t comfortable with doggos. As an alternative, you can use baby gates, but keep in mind that lots of puppers are stronger than non-furry children -- a toddler gate might not hold up.
