13 year old Min Pin started peeing in the house

Question
My 13 year old Min Pin has started peeing in the house. He has been trained since he was a puppy. Why would he do this and how do I stop him?

Answer
Get him into your veterinarian. It could be a bladder infection, or even bladder stones. He could also be urinating because of declining kidneys, but there are drugs to help with incontinence. You need to talk to your vet about this.

You could also get a belly band for him. Put a small sanitary pad in the belly band.  http://www.showpaps.com/bellybands.html
