Liam Berridge, who used to race for top trainer Howard Johnston, appeared from custody at Selkirk Sheriff Court and admitted a charge of shouting and swearing and making offensive remarks at his home in Hawick on Sunday afternoon.
The 28-year-old, who currently works at a stable yard in Carluke, had earlier been out for a meal with his partner but a row started as he wanted to go to another pub.
Depute fiscal Tessa Bradley said he was shouting obscenities at her and threatened to leave her and take all their money.
When police officers arrived at their home in Waverley Cottages, Berridge replied: “Can you not have an argument now?”
Defence lawyer Ross Dow said his client was a first offender and it was at the lower end of the scale as far as domestic arguments went.
Sheriff Craig Turnbull ordered Berridge to be of good behaviour for the next six months and deferred sentence until December 18.
