I'd be interested to see what the vet says. I adopted Tucker from BRAT August of '06. He was almost 4yrs when I got him. For the first 6 months he was peeing, and, initially, it was trails. Trails across the sofa, trails across the floor, and, one trail across the bed. I figured it would stop after a while, but it didn't for a LONG time. On one occasion, I had just taken him out to pee, and he did, and then left him for an HOUR and came back to a puddle in the kitchen. At this point I was convinced that it was separation anxiety or just outright spite for being left alone. I focused on my relationship with the dog and becoming the 'pack leader'. August will mark the year point and he has only peed in the house once for over 3 months now. I don't know if this relates all that much to your issue aside from him being a male and leaving a trail (ha ha, rhymes!). Perhaps once your's is more acceptable to you leaving him alone and knowing you are coming back, he'll stop peeing everywhere. I feel your frustration, trust me, I do. I have a lovely faux microsuede sofa and he couldn't just pee on one cushion. He had to get all three back cushions, which, of course, drained onto the seat cushions, and then down the crack between the chaise and the long sofa soaking the sides of both. Cleanup took DAYS!
