High fever in dogs can be a symptom of various underlying conditions, including infections and immune-mediated diseases. Accurate diagnosis and appropriate treatment are essential for managing high fever and its associated symptoms. Further research and awareness are needed to better understand and address the causes of high fever in dogs.
High fever in dogs can be a symptom of various underlying conditions, ranging from infections to immune-mediated diseases. Understanding the causes, symptoms, and treatments of high fever in dogs is crucial for effective veterinary care. This article reviews several studies that investigate different causes and manifestations of high fever in dogs.
Causes of High Fever in Dogs
Rocky Mountain Spotted Fever
Rocky Mountain spotted fever (RMSF) is caused by rickettsiae of the spotted fever group. In a study involving four dogs from two households, clinical signs included high fever (up to 40.5°C), abdominal pain, lethargy, depression, anorexia, and nystagmus. Treatment with tetracycline was effective in alleviating symptoms1.
Acanthamoeba Infection
Acanthamoeba infection, although rare, can cause high fever in dogs. A case study of a 22-month-old Spanish water dog revealed a high fever (up to 41°C) along with movement difficulty, stiff neck, and dehydration. The infection was confirmed post-mortem through PCR analysis of various organs2.
Severe Fever with Thrombocytopenia Syndrome (SFTS)
SFTS is an emerging zoonotic disease caused by the SFTS virus (SFTSV). Studies have shown that dogs infected with SFTSV exhibit high fever, anorexia, leukopenia, and thrombocytopenia. In some cases, the disease can be fatal, although many dogs recover from the infection4 5 6 9.
Clinical Manifestations
General Symptoms
High fever in dogs is often accompanied by other symptoms such as lethargy, anorexia, and weight loss. In some cases, specific symptoms like abdominal pain, conjunctivitis, and petechial hemorrhages in the oral mucous membranes are observed1 7.
Immune-Mediated Diseases
A retrospective study of dogs referred for fever investigation found a high incidence of immune-mediated diseases, such as steroid-responsive meningitis and polyarthritis. These conditions often present with high fever and other systemic symptoms7.
Diagnostic Approaches
Laboratory Testing
Various diagnostic tests are employed to identify the cause of fever in dogs. Radiography, cytology, and bacteriological and fungal cultures are among the most useful diagnostic modalities. It is recommended to withhold treatment before diagnostic investigations to avoid affecting the presence of fever and prolonging the time to diagnosis7.
Problem-Oriented Approach
A logical problem-oriented approach is essential for diagnosing fever of unknown origin (FUO) in dogs. This involves categorizing potential causes into localized or systemic infections, immune-mediated diseases, neoplasia, and miscellaneous diseases8.
Treatment and Management
Antibiotic Therapy
Antibiotic therapy is often effective in treating bacterial infections that cause high fever. For instance, tetracycline was successful in treating dogs with RMSF1. Empirical treatment with doxycycline/ciprofloxacin was used in a case of Acanthamoeba infection, although the outcome was fatal2.
Supportive Care
Supportive care, including hydration and managing symptoms like dehydration and anorexia, is crucial in the treatment of high fever in dogs. In cases of SFTS, monitoring and managing thrombocytopenia and leukopenia are essential4 6.
