	The confusion arises here because the bather is not asked if the puppy he is holding is a male, but rather if either is a male. If the puppies are labeled (A and B), each has a 50% chance of being male independently. This independence is restricted when at least A or B is male. Now, if A is "not" male, B "must" be male, and vice versa. This restriction is introduced by the way the question is structured and is easily overlookedmisleading people to the erroneous answer of 50%. See Boy or Girl paradox for solution details.
