What is an easy to install house gate for kids and pets?

Question

I need to find some that tall and wide. I've only seen 3 feet high and i need higher as my dog can jump higher.
Are there ones that install in a simple way?

Answer 1

About the best I can think of, if you are not up to constructing one, is to use two of the expanding gates, one above the other. You may have to find one that will let you attach it to the door frame or it may be to difficult to use.
