So, while I was investigating the Museum of Witchcraft, I bumped into a traveling dog-seller who reluctantly sold me a dog. I set up a second dog house in my backyard, watched as my adorable Dogmeat moved into it after I dismissed him in favor of Preston (1. Preston will give me a perk if I'm nice long enough, 2. Preston can wear Power Armor), and there they are, side-by-side in their little houses being dogs.
But it seems I can't get my new dog to come with me. I can't equip it, or communicate with it. (I'm super sad I can't equip it, Dogmeat wearing a bandana is ADORABLE and I wanted to give my bigger, meaner looking junkyard dog a Skull Bandana.) I can't even name it - it's just Junkyard Dog.
Does the Junkyard Dog - or any other purchasable or recruitable dog besides Dogmeat - have a purpose, or do they just look good occupying my doghouses?
