Get a peekeeper. It will hold your dogs diaper on while they play, otherwise as soon as your pup starts to get excited and scoot around the diaper will slip right off and you'll have pee all over your floors.
We use washable pee pads for on top of beds or in between the bed cover. @diesel_the2wheelddawg
They are machine washable and have made clean up so much easier. @meredith.n.lewis
