A 4‐year‐old, female Malinois shepherd dog was presented for chronic repetitive episodes of severe pain for over a year. Medical imaging findings and a positive blood culture were suggestive of a L2 vertebral bacterial osteomyelitis, most likely of haematogenous origin. The dog responded well to treatment with antibiotics and analgesia. A repeated computed tomography scan 6 months after presentation (and 3 months after antibiotic discontinuation) showed a clear improvement of the vertebral lesions. The dog is still clinically normal and pain‐free at the time of writing (3 years after diagnosis).
