The jury also found him guilty of ill-treating a dog belonging to the girl, who was aged 14 while much of the offending was taking place.
Before the trial began, the man had pleaded guilty to two charges of assault on a person in a family relationship, after admitting an attack on her on Father's Day 2020 in which he hit her across the legs and face.
The jury found the man not guilty on only one charge, that of supplying the girl with a class A drug, magic mushrooms.
Judge Collins thanked the "attentive" jury and said that because of their service, the girl could put the trial behind her.
