Determine pet owner from combat log event?

[MinguasBeef]

When you receive a combat log event from an action caused by a pet, how can you determine who the owner of that pet is?

Better yet, is there any way I can determine the owner's guid from a combat log event triggered by the pet?

The combat log does not contain pet owner information. If the player is in your group, you can save information about their active pet then compare that to combat events, but outside a group, there is no possible way to connect a pet to a player.
