Best thing I foung was to take her to the park, find a bench & pop her on the ground at your feet so every other dog can sniff her . She will be frightend at first but it's how they learn to be submissive to bigger dogs.
Thanks sarahse1 definitely a good idea when she is a bit older, at the moment she could catch something in the park with older dogs around as she is not fully vaccinated. That's why I was thinking about puppies her own age.
I may have to widen the doggy net!
