Dog pee pad tray holder.
Size: Small, Size: Small
I purchased this pre pad holder because my tiny pup would shred into a million pieces the pee pads I placed on the floor.
This is a sturdy, easy to use and clean produce. You just lift up the grief top tray, add a pee pad and close... all done. If you get pads that are a bit too large, no oroblem, you can easily find them to fit into the tray.
Quick clean up are with a wet wipes. For an occasional better clean... the whole thing can be washed in a bath yup or outside with a garden hose.
Best of all, my pup seems to know exactly what to do with this tray!
I would definitive comment and buy again. Actually, I have recommended it to several people.

Keeps the wee wee pads securely snapped in so puppy won't run away and play with them
Size: Small
My maltese puppy would run away and play with the wee wee pads if they weren't secreted inside a holder like this that straps them down. He uses the wee wee pads in this holder very well. I would give this five stars, but my puppy likes another kind of wee wee pad holder that has a plastic grate over it just a tiny bit more. I bought two different kinds of wee wee pad holders to keep at different locations to see what he liked to use. He uses both, but prefers the grated one just a little more. Even so, this is a quality wee wee pad holder and the pads snap in so easily and securely. Great purchase.
