It may affect organs such as the liver, spleen, kidney, lung, and musculature, and rarely, may be detected in the central nervous system. In this report, we describe the occurrence of a TVT causing spinal cord compression in a dog, and the results of its treatment with hemilaminectomy and chemotherapy. Case: A six-year-old male Dalmatian dog was referred to a veterinary teaching hospital with nonspecific abdominal pain. Laboratory examination showed no abnormalities; survey radiography revealed a moderate fecal retention. The dog received painkillers and dietary guidelines. However, the patient was brought again to the veterinary teaching hospital nine days later with paraplegia, worse in the left limb than in the right, but with normal nociception. There was a cutaneous trunci reflex cut-off at the T10 vertebra, also worse on left side than on right, along with spinal thoracolumbar hyperesthesia. During [...](AU)
