Since the revised Animal Welfare and Management Law in Japan became effective on June 1st, 2022, it became mandatory for pet dogs and cats to have microchips implanted and registered prior to be sold. Two cases of spinal cord injury as the result of inappropriate microchip implantation in puppies were referred to our facility, of which were diagnosed by cervical spinal radiography and computed tomography (CT). While adverse reactions following microchip implantation are rare, the possibility of iatrogenic spinal cord injury remains a serious complication. This is the first report of adverse reactions following microchip implantation in Japan, and it alerts the possibility of iatrogenic spinal cord injury secondary to inappropriate microchip implantation, where adequate training and extra caution is crucial especially in small light-weight animals.
