My almost 5 year old dachsund/beagle mix has recently begun urinating in the house. It got especially bad tonight, when he decided to walk over, right in front of me, and urinate on my shoes. What could cause this? I did recently move him to an apartment instead of our old house with a big yard but he gets walked about 10 times every day. Any ideas?

It may be the change of house, change of routine he could be nervous or protesting the change or ut could be a medical problem.

I would consider asking a vet. It would be the best idea for now.
