England's Andrew Raitt, who was seeking six million pounds in damages, was awarded 4,900 pounds in December for the incident that took place in 1995.
An appeals court on Wednesday upheld the lower court's decision.
Raitt claimed the 1995 dog bite took one-half centimeter off his left pinkie finger. He also said he lost feeling in the finger after he was bitten by the dog, an Alsatian named Zomba, at St. George's Hill Golf Club in southern England.
Raitt, an assistant pro at the club, was trying to stop a fight between the Alsatian and his own dog. Raitt sued the dog's owner.
The initial trial judge ruled there was 'no evidence' that Raitt's career had been affected by the incident.
The appeals judge agreed and said it was 'wholly speculative' to calculate Raitt's potential loss of earnings.
Raitt, an English school champion in 1986, turned pro in 1994.
He is completing his fourth full season on the PGA European Tour.
As of Wednesday he was ranked 142nd on the tour's money list with just under 125,000 pounds.
