help 2 year old female german shepherd
hi, I've adopted a 2 year old female German shepherd on wed and she was fine around strangers. Now she has become very aggressive to guest I have at my house and when I got my daughter this weekends.. Its starting to take 30 mins before she will let anyone touch her. The second day i had her she was fine with anyone just sweet as she could be even dropped her off at the groomers? If anyone could give me any advise it would be great.
