Yes, Torchlight II features doglike enemies.

 

That's not even slightly a dog. That's more like a rhino-warthog. Dammit. D: Are imagined beasts completely out?

So Ched, I'm really curious now - what IS the story behind this guy needing a game without any animals in it?

 

And yet no compunctions about killing humanoids? Huh.

 

Does he have a mental health issue perhaps?

Has he tried kids games, or just puzzle or strategy games? He's not going to have much luck in action games, but there are some great games out there that don't rely on combat at all.

 

I know it's not an RPG, but has he tried a game like Portal? I think it's one of the best games for non-gamer types.

 

Portal 1 an 2 should be a great option, albeit not an RPG.

Stardew Valley is an RPG where you don't really harm animals, IIRC although you do harm bugs.

Recettear is also mostly stuff like goblins, goo and bees. Can't remember dogs and stuff per se, but neither this nor Stardew Valley do have multiplayer.

Not sure how much help this is though.

Have you considered Space Engineers? It's not exactly an RPG, but you can play it in co-op with multiple people and shooting anything is entirely optional. It's been early access for a long time, but it gets regular updates and is way more fleshed out than most early acces titles.

The only other game I could think of is Don't Starve Together, but it does have hounds:
