After the latest update we got a new game mode with a Tower to climb and few more trophies, which I'm trying to get.
One of them asks you to Pet the dog that can be found
just outside the bridge in the camp
as you can see in this screenshot:
The problem is I'm missing that dog, it's just an empty spot in my game.
I thought this was a DLC only feature, but I own the Ultimate edition which includes all 6 DLCs.
