Where can I find Dogmeat after dismissing him to Sanctuary Hills?
He can spawn back at gas station where you first found him, or at one of the dog houses in Sanctuary.
If you scrapped the dog house that was there, I would go look at the gas station you first found him at.
Also, if you cannot find him at all, use the following (on PC):
- Open the Console by pressing ` (same as ~ on US keyboards)
- Type:
player.moveto 1d162 - Press: ENTER
This will teleport you to Dogmeat's location, allowing you to retrieve him and move the doghouse he went to.
If the dog still doesn't appear, make sure it isn't on the roof. If it is, build stairs to the roof.
You can normally find him at the Red Rocket Gas Station or in a Dog House at Sanctuary. But the dog house is located behind the yellow house with dog bowls in front of it.
