I kept getting reports this past few months about animals that couldnt be killed in zones. I did a test today and all could be killed in a zone except for the wolf confirmed. EDIT: It seems to be crocodile, wolf2, snake, tiger, panther will not take dmg in the zones.
Invincible wolfs
It seems like it is any animal that cannot be killed in zones now.

Ok I found out what is blocking damage to animals in zones, and its Undestr True. There needs to be a fix for it to check for animals as they cannot be killed by players or other animals with this flag on that I always use to prevent damage to deployables, props, candles, strobes ect.

The plugin needs a update to fix animals being invincible inside zones with undestr true flag enabled for buildings.
