Use of resilience and discipline to recover fatigue and stress

By Dedal, in WFRP Rules Questions

It is said on the small but vicious dog sheet that the pet recover obedience with animal handling as PC fatigue and stress with resilience and discipline. On the description of those skills I can see that effectively resilience and discipline can be used that way but I can't find how to do it. Is that action cards, or some rules I missed ?

Rally Step p13 ToA

Fatigue & Stress p62 corebook

thx, I didn't remember Rally step rules, why is this in ToA... ? But I should think of it.
