How do you lose a mate in wolfquest

well... a grizzly could kill him / her .

*Note* by KoaWolfQuestMod:
Normally, your WolfQuest singleplayer mate will re-spawn (come back to "life") if they die. It is impossible (to my knowledge?) to truly "lose" or make your mate disappear and never re-appear.
Sometimes, glitches/bugs may make your mate stay in a different part of the WolfQuest map or prevent he/or she from returning to your side.
