Can't Disable collision when Wolf is dead!

HEY YOU GUYS!!! Chunk impression off

Basically I have a problem that when i shoot and kill my wolf or zombie character the player character (ME) gets stuck on its collision. I have to jump a few times in random direction to get out of its grip and be able to move freely again. Is there a way to disable collison after the wolf or zombie is dead?

THX for helping you guys!
