Suspected hare coursers near Aldbourne did a runner before police arrived on Tuesday afternoon after being disturbed by gamekeepers.
They made off so quickly in their Green Subaru Legacy estate car that they left a whippet-type dog behind, said PCSO Jonathan Mills.
Police received a call at about 4.45pm to say that suspected hare coursers were driving round in a car with dogs in it and tearing up fields between Ogbourne St George and Aldbourne.
PCSO Mills attended in a marked police car but said that by the time he arrived the suspects had driven off, probably realising they had been spotted by the gamekeepers.
The registration of the Subaru was traced to an owner in Southampton and, said PCSO Mills, had not been linked previously to coursing.
Police inquiries into the incident are continuing.
