hello,
i got my remy #1, when she was 12 weeks old. when i got her, she was the same way.. very very shy. eventually she grew out of it with my fiance and i. the entire time we had her till she passed away, she was shy when she met new people, she was "shy" at first, but opened up to them eventually... she is still a puppy, im sure she will grow out of it.
good luck
