"I previously owned the 60 lb version of this crate and had few complaints. My German Shepherd puppy fit in there from 4 months old to 6 months old before having to upgrade to the 90 lb crate.
I cannot stress enough how flimsy the 90 lb crate is. My 55 lb, 9 month old puppy can break the front and back doors down and charge right out without any trouble. This is NOT SECURE for a large breed dog who is intent on getting out.
The 90 lb crate is poorly designed for large breed dogs--avoid it at all costs!!"
