I am having problems with my 2 year old adopted mongrel. He has been with us for approx 4 months now and he pee's up the table leg or the door every morning, even though the door is open. At first I thought it was him marking his territory as I have another male dog, but he is continuing to do it - it's just a little spray, not as if he is desperate to pee. I have used the usual products, but nothing is working, even 'rubbing his nose'! My OH is now saying he will have to live outside unless I can cure him! Help please he is the gentlest dog and loves to be looked after.
