Trained dog going tinkle inside

Question
We have 3 Dachshunds in our house. One of them,a male, has started to tinkle around the corners of my bed. We clean the areas thoroughly and we take him outside when we catch him but he still does it. He even does it when we are in the room. What can we do?

Answer
Well first if he isn't neautured,getting him done may eliminate this problem,as intact males will often mark,even inside

Also cratting may work as well,by keeping the dog in a crate at all times except to take him outside to feed him ect and do that for about 2 weeks,then slowly let him out more,and if he makes another mistake back in the crate he goes for another week

Also some medical problems can cause the dog to urinate more then usual,so it might not hurt to have your vet check him out as well
