Do enemy animal companions give XP?

So I’m creating an enemy level 9 druid NPC for my Pathfinder game I DM.

The enemy has a bear as an animal companion and I want to know if I should reward XP for killing the bear, in addition to the XP from the druid.

So this is supposed to be a CR8 (druid level 9). But does the enhanced bear add challenge to the CR level and XP gain?

I already know that creatures summoned from Convoct Monsters XX do not provide XP, but does a companion?
