Dog helmet

The dog helmet is a piece of dog headwear in Fallout 4.

Gameplay
It appears to be an armored version of the spiked muzzle with metal plates and additional bolts, though it doesn't provide any resistance. It also has holes for both Dogmeat's eyes and ears.

Locations

 * One can be found in a small cave guarded by three mongrels, about halfway between Walden Pond and Rocky Narrows Park, along with a chain dog collar and some dog armor.
 * Dropped from attack dogs.
