Dogmeat is quite a companion -- almost like a real dog when he's not doing egregiously silly/suicidal things. One Fallout 4 fan, however, didn't think he was real enough.
Over on Nexus, modder 7iger explained:
"I created this texture using photos of my pup, 'Pirate.' He's a kelpie x blue cattle dog and a loveable mutt. After posting [about it] to reddit, some users actually wanted to use my crappy re-texture so here it is."
It's still early days for Fallout 4 modding, so 7iger couldn't recreate their loyal canine from the ground up. They did, however, nail the fur pattern and signature (?) bandanna. Here's their dog in real life:
And here he is in-game:
This will, however, probably lead to something of an awkward situation. I mean, imagine it: Pirate whimpering at 7iger's heels for his daily walk while 7iger goes on endless post-apocalyptic adventure walks with virtual Pirate. We live in strange times.
