I'm sure they're adopted. I can't cage them and it says "owned by Urist McDwarfydwarf" or whatever in the animal menu and they all have names.
Are they only being adopted by dwarves that "love dogs for their faithfulness" in their profile descriptions?
I'm not sure, I'll check. But there's like eight dwarves that have adopted them at least.
