My 16-month old Jack Russell pees inside the apartment and on the corridor of the building in the morning before we take him out. He started this when we moved into a new apartment three months ago. At the beginning he peed inside the apartment at night and now he does it early in the morning just as we are about to take him out. On the other hand, during the day, he is very well behaved and can stay alone for up to 12 hours without doing anything. I need some insight into this as we don't know what to do with him anymore and how to stop this. We have tried to respect all the general rules: taking him out late at night, taking his water away at night, waking up early in the morning to take him out, etc. Does anyone understand why there should be such a difference between daytime and night time? He didn't used to do this in the old apartment. I really need some help as! Thank you!
