We rescued a lab mix and he has continued to grow longer and taller.  He seems to be mostly all lab, but obviously mixed with something else because he has the longest legs and is really long.  I ordered this crate because he outgrew 2 other ones we had...his head hitting the front and his bottom touching the back.  This crate works perfect!! He has PLENTY of room to stretch out, turn and move around.  I love that it has a side gate as well, which is really big so it gives ample room for him to get in.  It was super easy to assemble (no tools needed) and it folds back together just as well in case we need to travel!  Definitely worth the money!!
