The 36-year-old, from Bristol, denied rape.
He also denied two charges of assaulting a child by penetration and sexual assault of a child.
A jury of six men and six women took six hours and 30 minutes to convict him of rape but clear him of all other charges.
Judge Julian Lambert told him: “This was very serious sexual abuse of a young girl.
“She was isolated and lonely and you preyed on her.”
Dyer said no intimacy with the child took place and denied all charges.
Sarah Regan, prosecuting, told the jury Dyer subjected the girl to a five-minute attack.
Miss Regan told the court: “(The complainant) said it really hurt and at one point he whispered something like ‘don’t worry about what you’re not supposed to do.’
The jury was told the youngster realised there was a stain on a textile, and had been able to put it in a bag, and take it to police.
Swabs were also taken from the teenager, which provided a mixed DNA result from her and Dyer.
The court heard that Dyer told police nothing improper happened.
When asked about the DNA finding he said: “It does not make sense to me.”
Asked for an explanation, he told police: “I can’t. If I came up with an explanation I’d be lying.’
