i got a new addition to my family just before xmas and she is extreamly shy,

to the point that she constantly growls at my other 2 big dogs and she has even snaped but luckily my other 2 dont seem to be bothered and infact chaya is a little scared

. has anyone any ideas on what i should do or should i just leave her to come round i no it is still early but i dont want her thinking she can bully them, as she could get hurt if chaya decided she wasnt going to put up with it, i have her on a weeks settle down time and can take her back but she is so sweet, i was wondering if she would settle or is she set in her ways now... she is 2 years 3 months....or would she be best with no other big dogs.
