I do not know excakly what you mean but...
Hronec did got into he´s "Ghostage" at 12 moth of age, he was barking at stones and runing from dangeraus shrubs
Some people was OK, but not men whit a back pack, and we was walking in the mountins, so it was many stones, shrubs and men whit back packs
They all did luck OK to me, just see my photos... Nothing to be scared off
Very best regards / Mikael
