A 63-year-old man in Germany who contracted a rare bacterial infection after being licked by his dog has died, prompting doctors to caution pet owners to be aware of any unusual symptoms.

According to a new case report, the patient presented at Red Cross Hospital in Bremen, Germany only after three days of severe symptoms. Initially, he had experienced flu-like symptoms, including elevated temperature and difficulty breathing.

But the day before he went to hospital, his symptoms took a nosedive. A rash had bloomed on his face, and he was experiencing nerve and muscle pain in his legs. Closer examination revealed subcutaneous bleeding on his legs.

In addition, he had kidney injury and liver dysfunction, as well as hypoxia, lack of bloodflow to the muscles, and he wasn’t urinating.
