Challenges in the diagnosis and management of brown widow spider (Latrodectus geometricus) envenomation in dogs

This study reports two cases of araneism in dogs caused by the bite of the brown widow spider (Latrodectus geometricus), one of which resulted in death. The first case presented mild signs, successfully treated with medication and ice packs. The second case, more severe, involved exacerbated local signs such as extensive edema and ecchymosis, and diffuse cutaneous hemorrhage in the affected limb, as well as systemic signs, including vomiting, tetraparesis, ataxia, and epileptic seizure, culminating in renal and hepatic failure, circulatory collapse, and death. The treatments employed were based on the symptoms and included the use of analgesics and anti-inflammatories. The study highlights the importance of early diagnosis and appropriate treatment, including the use of specific antivenoms in more severe cases. It emphasizes the importance of preventive measures, such as the use of insecticides, to prevent future accidents. Awareness of the clinical signs of poisoning and the available treatment options is crucial for healthcare professionals and veterinarians to ensure proper management of these incidents and minimize their consequences.
