The wet state of wolves isn't saved to NBT

The Bug:

The wet state of wolves isn't saved to NBT.

As a result of this issue, the wet state of a wolf resets when its NBT data is reloaded. For example, upon the wolf changing dimensions or the world being reloaded, its wet state isn't saved.

Steps to Reproduce:

1. Construct a nether portal in the overworld and ensure that the nether dimension chunks are initially loaded.
2. Tame a wolf and set the weather to "rain" so that it gets wet.
3. Push the wolf through the nether portal and then you yourself enter it as well.
4. Observe the wolf's wet state.
5. Take note as to whether or not the wet state of wolves is saved to NBT.

Observed Behavior:

The wet state of wolves isn't saved to NBT.

Expected Behavior:

The wet state of wolves would be saved to NBT.
