TidyFriend 30 x 36 Inch Dog Pee Pad Holder Tray - Non-Slip Silicone Puppy Training Pad Holder with No Spill Design, Easy to Clean & Store (Light Grey) - Perfect for Housebreaking Puppies & Senior Dogs in Apartments

This silicone pad-holder is the greatest innovation in indoor-dog-elimination-management since the pee-pad itself. Makes earlier versions obsolete in our household, and we have fourteen rescue dogs.The holder lies flat and stays put, doesn’t slide around when stepped onto or make sounds that can spook small neurotic dogs. Its low profile invites them onto it. The underside (actually all sides) is much easier to clean than other designs we’ve used - a real labor-saving improvement. Hose it off, rinse in sink/tub, soak up with paper towels or spray cleanser and wipe.The flexible material allows you to bend one side up against a wall if your male dog lifts his leg, or if you’re fitting the holder into a tight space in a temporary location for example. When lifting one side vertically you’d need to tape the pad to the uphill edge because no fasteners are provided. But the wall’s protected.The shallow raised lip isn’t so high as to discourage dogs from stepping over it onto the pad, but is high enough to contain overflow from “edge-pee-ers” which mine unfortunately are. We previously used a hard plastic frame that clamped the pad into place but was very difficult to clean, then switched to just overlapping pads on the floor without a holder - always resulting in pee running between pads onto the floor. This tray keeps the dogs where they belong much better than the other two options.The size we got accommodates extra-large-sized pads with a spare inch around the pad’s edges inside all four borders, which IMO is how it should fit. You don’t want pad and holder to be the same size - or even worse, the pad to be larger than the holder - which would overcome the ridges’ barrier function. Pad dimensions vary, so my advice is to plan for at least this extra inch of room on each side, whatever your pad measurements may be. This extra space seems to encourage our dogs, at least, to move in from the outer edge of the holder. We now get dramatically less spillage. Your mileage may vary of course.One caveat: due to silicone’s inherent tackiness the pads stay put on this tray under normal use, but they won’t if your dog’s a pad-digger or -ripper, as many puppies are. There’s no way to fasten the pad securely into this holder. I much prefer this streamlined design because my dogs don’t dig and extra features equal more parts to clean. But this won’t work in every situation.
