Had to return it several times for a close enough fit. A size XXX is actually a large adult size and medium fit around the arm/shoulder area. Finally gave up and got a full refund.

This item does not heat despite being turned on. In addition, the rack was nearly impossible to put together to be free standing. The provided screws were too big for the holes. Terrible product! To top it off it had absolutely no instruction on how to put together as freestanding.

My husky loves these! They're all natural and edible. Not like the plastic ones that can hurt her digestive track or the ones made from wheat which causes allergic reactions. HIGHLY recommend these!
