Before you give the pup a bath has the pup been bathed before? Have you used shampoo for humans? If so chances are you have burned the pup using a product not designed for the pup.
Go to the pet store and buy some dog shampoo and give the pup a bath. You should also wish to prevent that dog from scratching the area which the bald spot has developed.
