Per Giltirn:For the time being, casuals like myself who don't want an entire playsession ruined by a ninja dog, hit F1 and type 'debuff buffNearDeathTrauma' and it goes away. You can also modify buffs.xml in SteamLibrary\SteamApps\common\7 Days To Die\Data\Config and go to the entry with line beginning "<buff name="buffNearDeathTrauma"", and set the duration to 900 (15 mins).
