Wolves' state becomes pseudo-death state when you kill it. It means, the wolves will in 'death' condition, but still technically alive.

What I expected to happen

The wolf should be in truly death state.

What actually happened

The wolf in pseudo-death state. Meaning, you can still hurt and adjust the posture, but the death animation freezing in the end.

How to Reproduce

1. Prepare items: a wolf spawn egg, a sword with Fire Aspect II and a bone.
2. Place the bone in the second welding slot (left hand if you're right-handed)
3. Spawn the wolf
4. Select the sword and hurt the wolf
5. Click the bone immediately after hurting
6. Click the bone again immediately when the wolf health near zero (or near death). You can use health meter mod to see the health of the wolf easily
7. You should get the wolf in the 'dead' state. But, if you hurt it, it works. Also, the wolf position still can be adjusted with bone

Why This Could Happen?

I don't deobfuscate the source code, so I don't know exactly about the root of the problem
Initially, Minecraft assumes you are killing the wolf. But when you tame it, the health of the wolf expanded, resulting freezing of the killing process, meaning the wolf has been animated death animation, but still technically alive.

Sorry if this problem is duplicate of other problem, although I already searched the bug but no results. Thanks.
