A seven-month-old boy has died after being bitten on the head by the family's dog in southern Germany.
Police in Hesse state said it is unclear why the dog attacked the boy.
The dog was taken to an animal shelter, where it was described as aggressive.
The baby's 23-year-old father called emergency services immediately after the attack, police said.
The boy was taken to hospital where his condition was initially stable, but he died in the evening.
The incident in Bad Koenig, about 45 kilometres south east of Frankfurt, took place almost a week after two people were killed by a dog in northern Germany.
A 52-year-old woman and her 27-year-old son were killed by a Staffordshire terrier they owned on April 3 in Hannover.
Hesse police said the breed of the dog in the latest attack was unclear, but it appeared to be a mix including Staffordshire terrier features.
Germany's 16 states each have different rules for keeping certain dog breeds, though many require a special permit if people want to own pitbull terriers, bull terriers or Staffordshire bull terriers.
According to Germany's Federal Statistical Office, 64 people were killed by dogs in the country between 1998 and 2015.
