I highly doubt it is a "stud" problem. 2 of my bullies do that and they are girls. hee hee
Another very wise person told me this, about when they are puppies. See if you can relate.
"When you bring a new puppy to your home, do not overly praise them when you see them. (like when they see you first thing in the morning). Wait 20-30 minutes to give them goo-goo ga-ga type of attention. When guests come to your home, ask them to please ignore the puppy for the first 20 minutes they are there. While they are puppies, they learn that when someone comes to the home (especially if you invite them over to meet your new puppy), that they are the "star". This behavior will continue throughout adulthood, and they will think everytime a guest visits your home, that they are there to see them. Thus, jumping and over excitement will occur".
My point is this, he obviously thinks this is normal for him, to get excited when guests come over.
What to do about it? Wish you good luck. I guess you can have people who may be willing to help you and come over and ignore your bully as much as possible. I know I have not been able to correct this behavior in my two. I gave up....
