The spawn events minecraft:entity_born & minecraft:on_tame cause wolves to appear red

Caused because the wolf render controller switches to the tame texture when query.has_owner instead of query.is_tamed. These events leave the wolf in the invalid state of being tamed but having no owner. Only the tame texture has the magical alpha channel set to mask out the hardcoded color overlay, so applying it to the untamed texture results in this

In 1.16.20

Me and my cousin was messing around with a command block that summoned tamed wolves ,but i dont think they had owners so we got a bunch of red dogs. We thought at the time (late village n pillage or early bees and bugs updates) they were trying to hide among the red sheep!  

This has something to do with the dye color of the wolf, but red is the default color. If you dye these red wolves, you can turn them other colors. 

you can use dye on the wolf to change it's fur color.

It would be nice if they made it a feature with a new command like  /summon wolf ~~~ minecraft:color=red

to fix this who ever did the command gets the wolf tamed to them

this did happen with structure blocks in my clone machine but now that is in good working order

*Affects 1.16.221, also command block users love this glitch because it allows for more customization. I would be sad and also many others would be too if this got patched. If it is reimplemented (assuming they fix it and decide to make it a feature) it wouldn't make sense to make it a spawn event like Mike Shultz suggested. However, this might be the only option as it doesn't seem like the devs intend on adding more /summon options (cough NBT cough).

affects 1.17.11
