The Diamond Dogs are a group of people founded by Ted Lasso. The group includes Ted, Coach Beard, Nathan, and Higgins as they tried to sort out relationship problems within the group but also for the people. Other names for the group included "Ted Lasso's Personal Dilemma Squad", "The E.Q. Warriors", and "the Proud Boys," which caused Nathan to vomit.
The group started when Ted confessed to them that he had slept with Sassy on the night of the karaoke party after the game between AFC Richmond and Everton F.C. in Liverpool. Beard, Nathan, and Higgins said Ted should not be worried about this as he enjoyed himself and had also just divorced form his wife, Michelle.
Later that day, Roy visited Ted to ask for some advice and Ted convened the "Diamond Dogs" to try to talk through Roy's relationship problems with Keeley. After discussing the problem, the Diamond Dogs agreed Roy should not worry about seeing Keeley and he should forget his hatred for Jamie and his past relationship with Keeley, and focus on the future positive relationship involving himself.
