I actually have a 3 acre pasture (fenced) that he can get his exercise in and we are making sure he is in another room before we open an outside door. I can no longer take him on walks outside of the property due to his anxiety. He will mark nearly every three feet (someone mentioned that it sounded like he was leaving a "trail" so he wouldn't get lost) and start looking worried.

The vet only wants to do tests if he exhibits more symptoms. Vet has over 30 years of experience and doesn't like to do unnecessary things.
