2006–2008

In the summer of 2006 Care signed a 3-year contract with Harlequins. At Harlequins Care initially found himself understudying Samoan international Steve So'oialo at scrum-half but after disappointing results early in the season the club recruited the experienced Andy Gomarsall, a member of England's World Cup winning squad in 2003. This restricted his game time, he started in the EDF Energy Cup and European Challenge Cup games before making his first Guinness Premiership start for Harlequins in a 9–3 home win against Bath in January 2007.

The start of the 2007–08 season presented Care with a chance of an extended run as starting scrum-half at Harlequins as Andy Gomarsall and Steve So'oialo were away at the Rugby World Cup in France with England and Samoa respectively. He was selected for the London Double Header, the first fixture of the season, against London Irish at Twickenham. Care was prominent as Harlequins beat London Irish 35–27,^{[citation needed]} he was injured in the match and sidelined for 5 weeks. By the time he had recovered Gomarsall and So'oialo had returned to club action and game time was limited in the Premiership. He started several games in the Heineken Cup and EDF Energy Cup. At the end of the domestic season Care was shortlisted for the Guinness Premiership Young Player of the Year Award – he finished 3rd behind Ben Foden and the winner, Danny Cipriani.^{[citation needed]}

At the end of the domestic season Care was shortlisted for the PRA Young Player of the Year Award which was voted for by his fellow professionals – he finished 3rd in the voting behind Tom Croft and the winner, Ben Foden.^{[citation needed]}

The final was at the Cardiff City Stadium against Stade Francais. With Harlequins losing 18–12 with only 5 minutes to play Care produced a line break and chip kick to enable Gonzalo Camacho to score a try which was converted to give Harlequins a win, 19–18. The win enabled Harlequins to qualify for the Heineken Cup, for the 2011–12 season as the club had failed to qualify via the Aviva Premiership. Care scored 7 tries in all competitions during the season and was named in the ESPN Dream Team for 2010–11.^{[citation needed]}

He was taken to a station by officers and questioned about the offence before being released. Care was given a caution for being drunk and disorderly.^[6]

Care had recovered from injury in time to play in the play-off final at Twickenham as Harlequins beat Leicester, 30–23.^[8] Stephen Jones of the Sunday Times said "Danny Care at scrum-half had what may well have been the game of his career. He was marvellously sharp and his decision-making was immaculate".^{[citation needed]} Care made 16 appearances during the Premiership season and contributed 4 tries and 1 drop goal.

In August 2012 Care agreed a 3-year contract extension with Harlequins, committing himself to the club until June 2016.^{[citation needed]}

A week later at Murrayfield England again disappointed on Day 1 by failing to qualify for the quarter-finals of the Cup after defeats against Argentina and New Zealand. On Day 2 they won the Bowl beating Portugal 31–0 in the final. Due to the late withdrawal from the squad of England Sevens captain Simon Amor, Care was asked to take on additional responsibility by assuming the main play-maker role within the team.^{[citation needed]} He was the 2nd highest scorer in the tournament with 42 points (4 tries + 11 conversions) including 2 tries in a thrilling 24–19 victory over Australia in the Bowl semi-final which went into extra-time.^{[citation needed]}

2008–2010

In July 2008 Care was selected in the England Elite Player Squad for the forthcoming season. His early season performances for Harlequins earned him selection for his third England cap as starting scrum-half for the opening Autumn International against the Pacific Islands at Twickenham.

Care was selected to start in the opening game of the 2009 RBS 6 Nations competition against Italy but a slip on ice after a training session at the team hotel in Surrey caused him to withdraw with damaged ankle ligaments and his place in the team was taken by Harry Ellis. The injury meant that Care also missed the next game against Wales but he recovered sufficiently to take a place on the bench against Ireland at Croke Park, Dublin, where England lost, 14–13. Care was heavily criticised in the national press for his performance in Dublin.^{[citation needed]} Care retained his place on the bench for the final RBS 6 Nations games at home to France and Scotland. Against Scotland he was on the field as early as the 16th minute following a injury to Ellis. Care contributed a drop goal as England beat Scotland 26–12 to regain the Calcutta Cup.

Care was considered by many to be unlucky not to be selected for the British and Irish Lions squad^{[who?][citation needed]} for the summer tour to South Africa but he retained his place in the England squad for the end of season game against the Barbarians and the 2 match series against Argentina. Care started all 3 games which began with a 33–26 defeat in the "non-cap" game against an experienced Barbarians team at Twickenham.

After the Australian leg of the tour England moved on to New Zealand to play against New Zealand Māori in Napier in a "non-cap" game as part of the centenary celebrations for Maori rugby. Care started the game and scored a try late in the 1st half, but England lost the game 35–28.

During a Rugby World Cup warm up game Care received widespread praise, especially in Wales,^{[citation needed]} for his sportsmanship during the game in refusing to play the ball at the base of a ruck when it was clear that Welsh full-back Morgan Stoddart was badly injured following a tackle.^{[citation needed]} Referee Steve Walsh was forced to stop the game to allow Stoddart to be treated for what turned out to be a double fracture of tibia and fibula. The following week Care sustained a torn plantar plate affecting the big toe of his left foot, an injury which required surgery and which kept him out of England's squad for the World Cup. The medical reports confirming that surgery was required came just a few hours after Care had been informed by England Head Coach Martin Johnson that he would be included in the squad.^[13][14] Whilst recovering from his injury Care worked for ESPN and Sky Sports on rugby coverage as well as being an analyst for ITV's coverage of the 2011 Rugby World Cup.^{[citation needed]}

Care started an 18–11 win against Italy but returned to the bench for the championship decider against Wales in Cardiff. England had the opportunity to clinch the championship and a Grand Slam but Wales won comfortably 30–3, England's biggest ever defeat in the fixture.

Care was not selected for the 2013 British and Irish Lions squad to tour Australia. Greg Growden, writing for ESPN Scrum.com in Australia, said, "Danny Care's chances of making the tour were always going to be hard after spending most of the Six Nations series on the England bench, acting as Ben Youngs' back-up."

In August 2013 Care was named in the England Elite Player Squad for the forthcoming season.^[16]

Following the 2024 Six Nations, a campaign where England finished 2nd, Care announced his retirement from international rugby.^[17]
