Has anyone made a mod so you could actually have like 3 or more dogs in a pack and have them attack other creatures and npc's??? Would be kindda sick to make a bunch of German Shepards into a pack of attack dogs

there is is a mod called Wasteland Whisperer or something that I think does something like that. Phalanx adds a Cyberdog follower (K-9) and it is a german shepherd based graphic.

Yep, that's WW, although it's currently a bit buggy. I'll have an update out for WW in a week or so, though.*
