The bug

Despite being a type of meat, fish can’t be fed to wolves to heal or breed them.

What I expected was:
When I right click a raw cod, cooked cod, raw salmon, or cooked salmon on tamed wolf, it will enter love mode (if the HP is full) or heal the wolf a bit (if HP isn’t full), and consume the item from my inventory.

Instead what happened was:
The wolf HP does not increase, nor does it enter love mode, and the item is not consumed from the inventory.

Steps to reproduce:

• Tame a wolf
• Attempt to feed it cod or salmon
• Nothing happens.
