I would definitely recommend it. For those times that you may be running late or just want to spend a little more time out, this gives you the ability to do so. I have ours hooked up to Hot Rod's crate which even expands the pen area a little more. I have his food and water and potty pad in it. I know that he is not getting into anything when I am not home and I know that he can drink, eat and potty if he needs to.
