Id take Dogmeat over the fable dog any day. Dogmeat and I have survived in 3 different post nuclear apocalyptic settings (yes he is in 2 your not looking hard enough). Id need leather armour and a sawn off though to complete the look. He would warn me of approaching enemy?s, protect me when I sleep, and rip the face off of Jimmys super mutie, and give me some one to ramble to and help prevent insanity due to isolation in the wasteland and constant violence, Dogmeat doesn?t judge me!
And dogmeat can beat up the fable dog

That or a Timberwolf omnimech, yes it?s not intelligent or anything like that, but who needs guidance when you?ve got banks of long range missiles on a walking robot.
Wait it has a nav system so as long as the gps is ok Ive got a guide to.
