WATCH: Dog trained to retrieve golf balls
Golfer Barry Gell picked up Jess from a kennel in 2005 and soon after started training her to pick up balls on the course.
Even more impressive is the fact that Jess has even been trained to not touch another golfer's balls, meaning she doesn't interfere with play.
Barry, 80, of Dunfermline, said: 'She has saved me a fortune.
'Golf balls can be expensive over the course of years, but I haven't bought a single ball for 12 years.
'The trouble is that I've got more golf balls than I would ever need now.'
