Apollo has a habit of peeing when he gets excited. He's a lab, so he gets excited alot lol He pees on the stairs (carpeted) that are by the front door EVERY day. I don't mind cleaning it up, he's still a puppy (1 year old or younger we think) but the carpet is starting to change color from his pee! Yikes! We rent and I don't want this bleached out stain to get bigger. My landlord will shoot me. Its the first thing you see when ya walk in the door. Does anyone have ideas on how to protect the carpet in this spot? Other then a doggy diaper. Someone suggested it to me, but I don't know if that would be ok to do. I can't put tarp down or anything cuz its on such an akward spot (the stairs) Any help would be greatly appreciated. BTW I clean up the stains IMMEDIATLY after they occur, but its still turning the carpet lighter in the areas he pees. Help please.
