I've found that sometimes I don't have Dogmeat near me, or anywhere else. So, I have to quit the game and reload it to find Dogmeat by my side.

Instead of reloading, is there a way to call your dog when not in sight?

YOU're probably gonna have to wait for modders to add this feature.

I had to use the console commands to get him once he got stuck somewhere in the wild. Sorry if you're on PS4/XboxOne.

It's a bit overkill but worked No idea if there are any other way to get him right back to you.

That also might, or might not, disable achievements for this particular run.
