So I have had real battles with my 11 yo dog marking in my house! This was the best dog before I had kids but ever since they came along he won't stop marking! He has been neutered since that's always the first suggestion. We try to keep him on our main floor where it's hardwood onlybut we like to have a rug in our family room. We have thrown out 2 shag rugs in the last 2 years after being repeatedly pissed on by this dog. We are looking to buy a replacement (rug, not dog ).. Suggestions on material that might be less appealing to pee on? Or a deterrent spray that actually works? We have tried vinegar to no avail. I would really likes soft surface for LO to play on, but preferably not one soaked in urine. Help!
