Upon /summon or summoning a wolf with a spawn egg the wolf does not attack me when hit. I am in survival and not in peaceful mode when this happens. I'm not sure if it's the same with naturally spawned wolves.

Steps to reproduce:
1. /summon or spawn egg in a wolf
2. Make sure your in survival and non-peaceful then hit
the wolf won't attack

UPDATE: i tried to reproduce this effect yet i believe it was an error on my part. If you can reprodude the effect then put evidence on here yet i don't think it will work
