I have an 8 month old male intact lab. He has been a handful to potty train but we got there. In July I met my fiancé that has a year old lab/Sheppard mix. Male neutered. Since they have met. My male has been "marking" ? He sometimes will leave the room and pee on the floor in a zig zag pattern when the other dog is here. They see each other every weekend. He has got so bold as to walk up and pee on our feet or as close as possible to us. When the other dog is gone he's perferg fine no accidents at all. They play awesome together but we are at our wits end dealing with this. He seems very disobedient when his buddy is here. Any info would be greatly appreciated. We don't know what to do.
