Brody doesn't mark in the house. He does mark every hydrant, tree and post on our walks though. He also only lifts his leg to pee outside. He isn't fixed yet at 9 mos. We are planning on it by the end of the month though.
The one thing that we do need to watch is his belly. We keep his hair longish and it has a tendency to collect wee. I'm sure there is a way to groom him that would lessen the problem. We just haven't found a groomer yet. In the meantime, we keep baby wipes handy to wash him up.
