I am using this cage currently for 2 of my 4 dogs, a little tiny 2 pound chihuahua and an 8 pound mix puppy. Sometimes they "share" and sometimes its just for one or the other. They both "fit" with room to spare. It comes with a divider if I want to keep them separate but so far I have not done so. It's too big to use as a housebreaking aid because it leaves them room to "go" without disturbing their natural instincts to keep their den clean but if I wanted to use it for that it could be done by using the divider. I hesitated for a long time about what size to get and this one seems nice, not too big or too small, it is certainly plenty tall for them.
After having this crate for two months I've come to the conclusion that this is AWESOME. I am buying two more... one for each dog. It is easy to store (folds flat), transport (MUCH easier to set up in a SUV or car than one of those metal crates), carry (the handle is nice), and clean (take off the cover; wash, dry, put back on easily and there are no issues with wear and tear from the W/D as of yet).
