I remember when I brought Rocky home
He was very attatched to me only. At our first dog meetup he sat on my lap why all the other dogs played and checked out eachother's people
Everyone was sharing what tricks they were learning, and when I told them Rocket is 6 years old and we are working on sit it was quite commical but I did say he will stand pretty and still all day long if I wanted and he walks beautifully
He had been trained for the ring and it just took a little to teach him how to relax, about two weeks of taking it easy and gradually gettin used to his new spoiled lifestyle. He still hardly ever left my lap though, he was my special sweet boy. Just give it some love and time your boy will come arround too.
