Rescue excavations carried out around Guimps (Charente, France) in 2011 unearthed several medievalstructures, including a silo containing a single dog burial. The animal, a young adult, exhibits numerousskeletal lesions. The excellent preservation of the remains allowed us to carry out a retrospective diagnosisand to demonstrate the presence of two independent pathologies, a radius-curvus and a medial patellardislocation. These conditions are of traumatic origin, as are the many fractures the animal also displays.The possible causes of such multiple injuries are discussed and the chronology of the lesions and theirskeletal distribution are examined in light of modern data. This leads us to suggest animal abuse as aprobable cause and, as almost no comparable cases were found in the bibliographical record, raise theprofile of the identification of animal abuse in archeology.
