I don't have any other resource that I have found which can answer my question or even give me a hint about what my GSD's recent behavior might be related to. So my pup is about 4 months and a week at this point, looking good, getting big (the bruiser is already 30+ pounds!), up to date on his shots, etc. He is to the point where he is GREAT with the kids, no more spaghetti worms, fleas are gone, etc. I have taught him successfully all the basic commands like speak, sit, come, easy, hush, etc. He has very few accidents in the house, no poop accidents anymore, goes on command outside, etc. I make sure to walk through the door first when we go on walks, he does a decent job about not trying to lead me and all in all he is a wonderful dog. Except...well..... a couple of times..... oh heck...He has peed ON me! Its only happened a couple of times at this point, but while the first was just a kind of nervous dribble onto my shoe, today he straight up walked over to me (15 minutes after being walked and using the bathroom), kind of went submissive and like he wanted me to pet him (tail wagging, etc.), and just unleashed this torrent of piss all over me. I tried to tell him stop, he peed more, I physically picked him up to bring him outside, he continued to pee all over me and all over everything nearby. by the time I got him to the door there was no point to bring him back outside, he was already bone dry and I was soaking wet. Does anyone know what this kind of behavior is indicative of? Has anybody else experienced this with their GSD? Is there something I can or should be doing to try and dissuade this? I don't get to play with him as much as I would like but he goes outside like a gazillion times a day for mini walks and twice a day for pretty decent walks, he has the run of the house during pretty much all of the day when he isn't in his crate as part of his training, he seems happy and eats and drinks well, displays affection towards me and my family (wife and kids); so why is he peeing on me?
