For the last few days my 3yr old jack Russell has been weeing in the same spot in the house. He would usually whine to go out if he needs to. Everything else is normal he is eating OK, but he is drinking a bit more than usual. Also I am 6 months pregnant.

The pregnancy can be what is throwing him off. New smells, new furinture, less time spent with your pooch and more time spent preparing for baby (congrats! ). The simplist changes can throw a dog off and make them act out in ways they have never done before. I would clean the areas with a good enzyme cleaner, I like using a water and vinegar solution with a few drops of tee tree oil in it. Take your dog back to basics and make sure he goes out after every meal, drink and play time. You may have to stand out there with him while he does his business, and praise like mad when he does his business outside.
