Dod was educated at home by private tutors and his family fortune, gathered from the cotton trade, meant that he never had to work for a living. He indulged his passion for the sporting life as both a scratch golfer and a big game hunter. He took up archery at the home of the Legh family, who had an estate close to the Dods in Cheshire and were one of the greatest names in the sport.
Neither Dod nor his sister Lottie took part in competitive archery until they moved from Cheshire south to Berkshire in 1906, where they joined the newly formed Welford Park archery club. Within two and a half years Dod had become Olympic Champion. William Dod mastered the torrential rain on the first day of the Olympic competition to hold a 10-point advantage. When the rain gave way to swirling wind conditions on the second day, Dod forged ahead and comfortably took gold with a margin of 47 points over Reginald Brooks-King.
He went to win the Grand National Archery title, effectively the British national title, in 1909 and 1911. Dod retired from competition after the 1911 championship and rekindled his love of golf. In 1912 he reached the 4th round of the British Amateur Championship.
After the outbreak of World War I Dod enlisted in the Royal Fusiliers and served as a private in the trenches for a brief time before successfully applying for a transfer to the Royal Navy. He spent a year as an administrative officer in France with the Royal Navy Air Service before being invalided back home to England.
