I had a post somewhere about whether male or females were more cuddly, because my male is a lot more cuddly than my female.
I don't know if you can tell or not from a puppy how they will be as an adult dog. I got Gus (my male) at 5 weeks old, and I could not tell then if he was going to be cuddly. Not sure if he is cuddly now because I carried him around so much and treated him like a baby (hehe) because he was so young and tiny. Izzy, my female, I got at 10 weeks and she liked to cuddle when she was a baby, but doesn't care much for it now. When she was baby, she could not fall asleep unless she was touching me, and if I moved, she woke up. She does sleep in my bed now, but just puts her head on my legs if she is cold. If I let Gus sleep in my bed, he would sleep on top of me, he likes to get as close as possible. He still sleeps in his crate..... he is 9 months and still likes to chew, so I don't trust him yet! Izzy is a little over 2 years old.
So. I am not sure how much you can tell from when they are tiny puppies. With both of mine, I noticed their personality develop as they grew. Just my observation with my pups.
