One is now starting a prison sentence while the other two received community service orders.
Police uncovered the incident, and more sex crimes, on mobile phones while pursuing another investigation.
Former publican and taxi driver, Peter Leigh, 73, Ian Chatting-Tonks, 63, and Elaine Pasquier, 67, admitted ill-treating a dog which had belonged to Chatting-Tonks.
The two men appeared yesterday for sentencing in the Royal Court and the Magistrate’s Court, where they were joined by Pasquier.
Leigh was sent to prison for a total of two years and 10 weeks, while the other two were ordered to perform community service.
