"Trainees quest" : to see the quest's target select the quest while in book ([TAB] Book > (while the desired quest is highlighted) Enter/LMB > a blue beam will appear + nishy will turn towards that spot). If there's still an issue feel free to make a screenshot with the quest's details and post it in here.
"hcard for the dog" : hcards are for objects, currently only available for Carrot, Magic Staff and Condom. Bone can be used as food for tamed fapets (preferably wargs and hounds) after feeding is unlocked.
