A woman bit another woman during a fight over how to discipline dogs in the eastern German state of Thuringia, local police say.
The women, both dog owners, began quarrelling after one of them spotted the other hitting their dog.
It then escalated into a brawl, with the women hitting each other.
The older woman who hit her dog then fell and dug her teeth into the younger dog owner's calf, German state broadcaster DW reports.
"The dogs only looked on and did not engage in biting" during the fight, German police said.
DW reports the women are due to appear in court on charges of causing physical injury.
