We tried several different styles of gates before selecting
this one as our #1 choice.
It works great for 4week old puppies and up - so you won't have an issue with your Chi getting under it. Now over it .... well Rupert can jump 4' from a sitting position .... so if you only have an older Chi in the house you can make it a bit higher hehe
We like it because there are no "holes" for little legs to get caught in. Some Chis will climb the gates with openings and you can get leg injuries very easy with those.
We also like it because you can mount it on the wall and just swing it open with one hand! They are affordable, readily available and we love that the manufacturer has excellent customer service. We needed to purchase a replacement mount for the wall and when I called to order it - they sent me 2 for free (and they knew we broke it!!)
There is also a
curved version of this gate now which is even nicer!!
