Peeping Fawn did not race at the age of two. She made her three-year-old debut on 1 April 2007 at Navan, finishing a well-beaten third behind Ezima. She finished third in her next start on 15 April at the Curragh, then improved to second on 29 April at Gowran Park. She finally broke her maiden on 16 May at Naas, winning by lengths from Katrisa. O'Brien then stepped Peeping Fawn up in class, entering her in the Irish 1,000 Guineas on 27 May. Sent off at odds of 12/1, Peeping Fawn led during the early portion of the race and came under pressure with three furlongs remaining. She was headed in the final furlong by Finsceal Beo, but held on for third. Just five days later, Peeping Fawn was entered in The Oaks where she was dismissed at odds of 20/1. She was restrained at the start of the race and stumbled around the two-furlong mark before settling near the back of the pack. She started a strong drive with over two furlongs remaining and moved into second place but could not get by Light Shift, who held on to win by half a length. On 30 June, Peeping Fawn went off as the 7/4 favourite against older fillies and mares in the Pretty Polly Stakes at the Curragh. She was held up in mid-pack during the early running then quickened in the final furlong to win by two lengths over Speciosa. "She's a typical Danehill who thrives on her racing," said O'Brien, "and being out of a Sadler's Wells mare obviously helps her handle soft ground as well as she does." Peeping Fawn followed up with a comfortable win in the Irish Oaks on 15 July, defeating Light Shift by lengths. Johnny Murtagh, who took over as her jockey from an injured Kieren Fallon, held her near the back of the pack during the early portion of the race. "When she moved up on the last bend," he said, "I knew she was ready to go but I said steady girl, not yet! When I did ask her to quicken up and get on with the job, she did it very, very well." Her next start was the Nassau Stakes on 4 August, where she again faced Light Shift plus top older horses Mandesha, Speciosa and Nannina. Speciosa set a brisk pace tracked by Peeping Fawn, who moved to the lead with three furlongs remaining. Mandesha made a late run to finish second but never threatened Peeping Fawn, who won by a length and a half under a hand ride. On 22 August, she made what would prove her final start in the Yorkshire Oaks, winning by four lengths over Allegretto despite being eased near the finish. "She's a very, very good filly", said Murtagh. "She travelled very well and she's up there with the top fillies I've ever ridden." Peeping Fawn was being considered for the Prix de l'Arc de Triomphe but O'Brien instead prioritized Dylan Thomas, who would go on to win the race. She was also considered for the Prix de l'Opera but was instead given a rest in preparation for a four-year-old campaign. She was named the Cartier Champion Three-year-old Filly of 2007. O'Brien originally planned to race Peeping Fawn in 2008 but she did not impress in training. After a June exercise gallop, she sustained a minor injury and was retired in August when she failed to respond to treatment.
