No description of the rapists. Given the crime and the location (North Rhine-Westphalia), they almost certainly have a migrant background.
Mitteldeutsche Zeitung (translated):
Her dog has saved a 23-year-old woman in Krefeld from gang rape. When the woman went with her pet on the night of Sunday shortly after one o’clock, she was ambushed in a forest by three men.
The police said the 23-year-old had an object hit on its head. The men overpowered the woman and put her on a tree. Then they began to sexually abuse the woman.
