I've had my maltese for 3 years now. Since i work 3 twelve hour shifts, i trained my girl to potty on towels. She's been absolutely great the whole time. But last week, i brought her to the groomer for the first time. Ever since then, she's been peeing on the carpet. She seems to avoid the bathroom now to use the towel. I wonder if her paw pads are sore against the slippery floor or something. I have no other explanation for it. Now i feel that i have to retrain her as if she wasn't housebroken. Has anyone ever experienced that?
