Let me say this - we own 4 Tucker Murphy crates and they are absolutely exceptional quality . I love they have locking wheels and are so easily to clean underneath.
We have a large romping Shepadoodle along with 3 chunky Bullies and they adore these crates for napping ! 
This is miles above those flimsy crates you find in most stores . Worth every penny ! 
Sturdy , slide secure locks and you can open the top of crate ! Dont let this sell out before you place your order !
