I'm going to mark this as fixed as there hasn't been any new reports since forever and testing my game, it seems fine.
If anyone still has it, please post.
My dog was not sick and was in a happy mood. My dog was at the home lot. When my sim came home from the vetclinic, where she works as a vet she gave the dog a wellness treat. Right after she gave this i noticed that the dog had this affraid of something moodlett and it stayed that way no matter what i did. After searching for a solution i tried the remove all buffs cheat and that seemed to help. So i do not think it is related to anything like sickness, but the wellness treat it self is causing the issue.
For anyone who wants to know, Misslittlesam has made a bugfix that you can use or use the remove all buffs cheat for it until it gets solved.
OH no! I'm so sorry, i did it again. It's littlemisssam.
