Could be your pup is still adjusting to it's new home.
My female had never been cuddly, it is almost like she gets too hot, or now that she is older, she likes to be independent and stay alert without distractions. She loves being a watchdog in every situation.
Yes and Yes. Prob. still trying to adjust to the new home and FWIW, all of my males have always been more "cuddly" than females.
