For those who have multiple GSD's do your dogs herd each other? Onyx won't let Kacie in outside if she is out first. Then she won't let her in. Same thing with poor old girl Clover. I have to keep Onyx inside when they go out. Onyx' mom Miyah is a working girl, she is on a horse farm and works every day with horses and when needed, cattle. I'm sure it is her natural instinct, but it does get annoying, especially to the other dogs. Anyone else with this "problem"??
