Does a pet bring bring back explorer's items that were found?

I'm playing fallout shelter, I accidentally left a dweller exploring the wasteland for to long, and he died. He had a pet, and when my dweller died his pet started coming back to the vault. I was just wondering, (because it's taking ages for the pet to come back), does the pet bring back what the dweller found before he died?

Yes. The pet will bring back anything equipped to the owner, as well as any items collected in the wasteland. For this reason, I often assign a pet to each dweller going into the wasteland as a gear recovery insurance policy, even if the pet provides no benefit in the wasteland (x2 healing, -crafting cost, etc.).
