Cash does it too. He is almost two years old and he still follows me around - especially when we visit my parents. They have two staffies and my family doesn't really like Cash because he is a lot more cheeky than the staffies and he gets into fights with them - nothing serious to date.
The cute thing is that I have taught him to choose between staying in or going out if I have to close the door. So I go: "In or Out?" and he decides for himself.

I have been calling him my "stertjie" (my tail)
