In general, males tend to be more affectionate than females, especially so in cats vs. dogs. However, that being said, I also believe that it's a combination of the animal's own personality, your personality and it's environment that all of it together greatly impacts how affectionate and cuddly your dog is, regardless of breed.
In my case, at least so far, lol, Molly is very affectionate, cuddly and sweet. So, I would imagine she would be as an adult too. At least I hope so. lol
