【Life Saver for Indoor Dog Potty Training】The potty system would be great helpful for indoor puppy potty training and convenient for senior dogs. If you live in an apartment without grass/always busy work/fur friends don't want to go out when rainy day, the potty loo would be life saver for you. 【Quick-Draining Fake Grass】When your dog relieves itself, urine drains swiftly through the grass into the tray, preventing wet, soggy spots on the pad and keeping the surface dry 【Washable & Reuable】The whole set indoor potty system is easy to clean with soapy water and dry quicky. We suggest to wash it every 1-2 days to avoid odor. You don't have to buy tons of disposable pee pads over and over again 【Sturdy Drainage Grate】 Crafted from heavy-duty plastic, this grate acts as a reliable barrier between fake grass mat and absorbent pee pad.

This familiar scent will guide them to pee in the right spot 【Indoor & Outdoor Use】Our dog potty tray ideal for situations where outdoor access isn’t possible: illness, extreme weather, or other environmental barriers.
