Hogg, who currently plays for Montpellier in France, admitted a single charge which related to repeated abusive behaviour towards his now estranged wife.
Over a five-year period, up to August of this year, he engaged in a course of conduct which caused her fear or alarm.
The court heard how the 32-year-old regularly shouted and swore at his wife while they lived in Hawick, as well as when they lived in Exeter while Hogg played for Exeter Chiefs.
At one point it caused her to have a panic attack – and she eventually took advice from domestic abuse services.
The charge also involved Hogg monitoring his wife’s movements through the Find My Phone app after they had split up in 2023, and him sending her sometimes hundreds of text messages in the space of a few hours.
Sentence has been deferred until 5 December, when a full mitigation will be provided by Hogg’s legal team.
Sheriff Peter Paterson allowed him bail until that date to await reports, including a restriction of liberty assessment.
