Back to basics, take him out regularly make sure he has emptied himself so to speak so there is nothing left. It may calm down with time after being away. Also try and not leave anything on the floor he can wee on for now.Any advice on stopping dogs cocking their leg inside? My 8 month male Brussels griffon just started after spending Xmas day at my parents (they have a 7 year old yorkie). He hasn’t had full access to the whole house unless supervised but now whenever he gets a chance to leg it out the kitchen he does it on anything lying around (laundry bag, daughters large toy, Xmas tree, outdoor sofa cushions we brought indoors).
He’s getting neutered next month.
Ive never neutered any of my male dogs and had no leg cocking issues indoors although one would mark for great britain out of the house
