Possibly the Club are recommending collars as part of their campaign(!) to make SM seem less of an issue in the breed.
Holly was walked on a collar and lead until she was two (and I found this site..). She has always hated puppias but really likes the Easy Walk, so that's what she uses. Amber loves puppias - any puppias, but she's especially keen on the over-the-head kind and she has always been walked in them after a scare with the Easy Walk when she managed to slip out of it. In a busy car park. That was scary...
Holly - 7years
Amber- 3 years
