I was just thinking about this and decided to post on it. Helena has mounted and tried to hump my 5 year old nephew on a few occasions. Now everyone in the room thought it was really hilarious.. I am actually laughing now thinking about it. BUT I know it is a sign of dominance so of course I did not let it continue and I told her no.The strange thing is Helena has never tried to hump anything or anyone not even another dog. She has only tried to do it to this kid. And she has been around several other kids male and female... Do you think he put off some sort of scent or something? Just odd to me.
