Answer
BEnadryl does not have much effect in dogs because most of their skin problems are NOT related to histamine.  If there are little bumps, that is probably infection and that is usually secondary to something else.  In a young puppy, I would think of something like mange as a culprit.  Ask your vet to check for that.  If the puppy needs antibiotics, they can prescribe them for you.
