Luck roll 19, pass
The dog simply barks, while you look about and find numerous bits of quite useful salvage. Several pieces of which make you wish you had one of your old laser pistols from the days in the army, but they hadn't let you take one of those home with you. You also find some more caps and ammo, as well as a sawed off shotgun in the backroom. And a Nuka-Quantum, which is glowing brightly still to this day.
You also learn about there being a cave by the edge of the hill, where pre-war, they dumped stuff, though given the moles here, its probably inhabited now. But the dog seems to be following you about, so perhaps it could tag along and help ya out if ya explored it. Or anywhere, really, if it came along.
