Local courts found a Borås woman guilty of causing grievous bodily harm when her Rottweiler attacked and severely bit two joggers in a wooded area on separate occasions last summer.
The convicted dog-owner is on probation for 100 days and must pay 25,000 kronor (about $4,000) in damages, according to local media Borås Tidning.
The district court held that the dog-owner neither had supervision or control of her four-legged companion as required by law.
In one incident, the dog allegedly charged a female jogger, tore through her arm muscle and continued to attack her legs and face. The victim finally fended off the dog with a sharp stick.
As the investigation pursued, authorities discovered that the Rottweiler had previously attacked another jogger in the same area without the owner being able to stop the animal.
During the trial, the dog-owner denied accusations that she had been negligent, maintaining that the dog had managed to tear through and escape both a leash and muzzle.
The courts could not validate such claims, noting that she neither had supervision or control over the dog as required.
The dog has since been put to sleep, at the mandate of local police.
