I am wondering how 'normal' it is for a pup to be very reluctant and nervous in new situations at this age and I'm curious if her behaviour is within 'normal'. She is 13 weeks now and we've had her since she was 8 weeks. We have been socializing her with new outings and people. But she takes a fair amount of time to warm up. Is this something she will outgrow somewhat as she matures?
