They are no different than people, in a way...
They all have different personalities. Some are more cuddly than others. Some are more outdoor-oriented than others. If THEIR mom is around, though, they will follow you everywhere you go and that includes the bathroom!
I've always found mine to be somewhat independent, but when they want mom they'll come looking for you. It has been my experience that when they are puppies that they are less cuddly than as they age, although they still do have their cuddle moments.
They are a most intelligent little doggie and like to play, play, and play and going for walks is their favorite activity as well as chasing and bossing the squirrels around. They are a very curious and active little dog. They will investigate everything in their environment and their yards.
