Reliable, absorbable.  Buy the ones that have the glue already attached to the flaps to close around your dog
Reliable and does the job for my old Maltese who was becoming incontinent.  Comes in three sizes small medium and large.  He was between the small and medium so I would get both and put a small one on first then cover that with a medium as when he did pee it would be a lot to absorb in a small one.  Highly recommend.
