Dog breed descrimination - showing up late un-announced

Nothing to add as I have the little dogs.
BUT We do have a friend who has a GS and she is most mild manner dog I have come across. She was a working & now retired LEO\Military dog who has a bad case of PTSD. BUT with me she is always mild and even tempered. She is deathly afraid of thunder storms and things like that. She likes my two dogs and is very patient with them.
So I feel your pain. but just remember its their campground they makes the rules but always check ahead of time.
