Hi just homed a rescue dog whose started leg humping. I think it showing off as it's only when we have guests or family members around. He gets 4 walks a day plus ball chasing out the garden and rope tugging. He has a good diet and the run of the house. I need to try and deal with this as I am getting concerned about visitors. Or last bitch was very good but I know he is just adjusting to us and home life as he had been kennelled for 2 yrs prior. He is sociable with other dogs doesn't bark when barked at and is generally very good otherwise. I have tried 'no' then Sit and even removing the dog for a few minutes but when he returns he sneakily tries humping again.
