Hi Kevin, I just posted an answer on your other thread regarding Baxter peeing in the house, I mentioned if he could have a bladder infection. Maybe it is his kidneys? The discharge and the blood could be related to why he is peeing and having accidents in the house. I would have the vet recheck him for a UTI, and also maybe check his kidneys, there is something going on there. Good luck, I hope your vet can figure out what's causing the discharge and the peeing problems. Please let us know what he says.
