He's begun just randomly peeing on the floor for no reason. I mean, he doesn't even go to the back door. I don't think it is a urinary tract infection as he manages to hold it very well in "his" spaces, but in the past two days he has had 3 accidents after not having any for a few months! also he's not enthused about going off the back porch for whatever reason, just like when he was a little guy (the reason then was the steps were a bit scary, but he is fine with steps now). I have to pull him off the back porch to go potty and ALL of our doors lead to porches. I don't know what to do and I am getting annoyed. I moved back to square one with the leash and him always being with me, going out once an hour. Here's hoping. Any ideas what could have caused this sudden relapse?
