    Comment on wording

    The question asks for the “number of dogs”. In the problem statement, we’re told that number is 2 (out of 3). Actually, it can be any even integer number (out of 3/2 that many), up to 2/3 of the total dog population (which is estimated at over 520 million).

    Had the problem asked for the fraction of dogs, then an appropriate answer is 0.67.
