Our 9 mos old 45lbs Husky loves the outdoors. I bought it coz I didn't want her to take naps on our concrete patio. 
She has loved this from day one! VERY durable and the mesh bed is breathable for her to help cool off.  I bought the largest one and perfect size for her to stretch and lay back. Super easy to install. No damage from shipping whatsoever. 
I love it!!

UPDATE:
Our Husky loves this cot so much that I bought another for indoor in a Medium size.  She now ignores our couch!
