Is it normal for a puppy not to like there harnesses, Every time I get Hatties out she runs and hides she is 20 weeks old and we have been putting it on her from when we first got her, it has also took ages for her to get used to a collar, but she will not move if I try to put a lead on it, at least when I do get the harness on her she seems to enjoy the walk. anyone else have the same problem and will she get used to it.
