Great for my English bulldogs. I have 4 mini English bulldogs. My heaviest 1 is 47lbs female. The girl in there now is 1yrs, 40lbs. I have a 6 month old 23lbs will be on the other side or my tri-merle stud 43lbs 1yr. Now if was a taller breed same weight. It may be a tight fit. I may try the stackable 4ft L kind. For my basement to keep anything I rescue off the floor. It has thick flat metal grid floor built in. Removable spill tray under it.  

Ps. The locks on both doors are side by side. Sometimes it locks the other door. Needing to be space out
