I love my little buddy Theo. He's almost 6 months old. He finally got really good at going to the bathroom outside and on his potty pad. He was 100% perfect with just a few misfired.
Now suddenly he's starting to mark things. Like I got a new chair and he marked it, then he marked my backpack, and a folder I had leaned against my bed, worst thing is he has marked on visits to my friend's house!
Anyone have advice for this? I haven't neutered him yet, he's like 3-3.5 lbs at the most and almost 6 months old...
