He lives in the United Kingdom, with his wife Bettina Hoy, who competes at the Olympic level for Germany. The Hoys are a rare married couple competing in the same Olympic discipline for different teams in the same year (see also Raphael Poiree and Liv Grete Skjelbreid Poirée).
In June 2008 Hoy was charged with animal cruelty offences relating to assistance offered by Hoy to one of his pupils, Dutch rider Madeleine Brugman. Stewards allege that Ms Brugman rode Sundancer 6 at Barroca d'Alva CCI*** in Portugal (8-12 March) in illegal spiked boots (news, 20 March). Ms Brugman and Mr Hoy were called to an FEI tribunal to investigate the alleged abuse of the horse.
FEI spokesman Malina Gueorguiev said: "Witnesses are saying they saw them both putting the boots on and taking them off the horse."
Hoy expressed surprise that he has been charged in an interview with an Australian newspaper. "Always the situation is that if a horse has any damage to it or any abuse to it, or there is anything in relation to a drug-related incident, the rider is always the one that is responsible," he said. In the same interview Hoy stated that he had made many enemies and that "I'm absolutely convinced someone is out to get me." When asked who these people might be he stated "I definitely can't say who I believe these people are." Herald Sun Newspaper
