Just wondering what people are using for a dog gate. I have several barriers that I am using but I need one that will specifically open like a gate and that you can step though (preferably with no rail at the bottom...no tripping factor

) My husband isn't as athletic as I am stepping over barriers (briefcase in hand) The opening I need to block is about 4.5-5 feet. My puppy is little not even 3 lbs yet so I'd like something that he will not be able to slip through or get caught up in. This won't be used (at least at this point) when he is unattended though safety is my utmost concern. I put him in his when I have to leave the house.
Thanks for your help!
