After Smokey was potty trained the only time he ever peed in the house was to tell me "Hey, something's wrong." He had a bladder infection. Has Malone had to hold it recently for longer than usual? Smokey had to be in his crate for 8 hrs one day and he wasn't used to holding it that long. He didn't pee in there (what a good boy) but he ended up with an infection.
Does it seem like he is urinating *a lot*? Is he drinking more water than usual?

Just something to consider.

Hope all is well though! Good luck.
