Wolves summoned using Repeating Command Block will make the noise indicating they are injured, even though they are at max health.

Wolves summoned using repeating command blocks, will cause the wolves to make the noise to indicate they are hurt even though they are at full health.

 

Command used: summon minecraft:wolf ~ ~1 ~ {Owner:player}

 

-Doing /summon minecraft:wolf ~ ~ ~ {Owner:player} in chat does not reproduce the same bug, only in command blocks.

-Using the NBT {Owner:player} seems to cause the issue.
-summoning regular wolves Doesn't cause the bug.
-Leaving and Rejoining does not fix the issue.
-It only fixes it when you heal the wolf after its taken some damage.
-Regular Command Blocks also cause the issue.
