Hello, I've had my Shi Tzu for about a year and a half now, and up until recently he used his pee pad regularly with no problems at all. Recently though, he sometimes uses the pad, and sometimes pees in areas around the pee pad, and sometimes next to the fridge and tables of the house. We thought it could have been that he doesnt like to use the pee pad multiple times, but he'll pee somewhere else even if its completely clean. It only happens with pee, he doesn't poo outside of the pad. We don't know what to do anymore, anyone have any ideas on how to help this?
