Dog Babesiosis: Tick-borne Protozoal Disease

Babesiosis is a serious tick-borne disease caused by protozoal parasites that destroy red blood cells in dogs, requiring prompt treatment and prevention.

Key Facts

Babesia canis and Babesia gibsoni are the main species affecting dogs in Europe and Asia
The disease is transmitted primarily by Dermacentor and Rhipicephalus ticks
Affected dogs show fever, lethargy, jaundice, and anaemia from red blood cell destruction
Imidocarb dipropionate is the primary treatment for Babesia canis infection
The disease is spreading geographically as climate change expands tick habitat ranges

Welfare Considerations

Babesiosis causes acute suffering through rapid anaemia, high fever, and haemolysis. Severe cases develop multi-organ failure. The disease can progress rapidly from apparent wellness to life-threatening illness within days. Pain, weakness, and the systemic effects of haemolytic anaemia cause significant distress. Tick prevention is the primary welfare intervention, and prompt treatment upon diagnosis dramatically improves prognosis.

What You Can Do

Use effective tick prevention products consistently in endemic and tick-active areas
Check dogs for ticks regularly and remove attached ticks promptly
Be aware of the expanding geographic range of Babesia-carrying ticks
Seek veterinary care promptly if your dog shows fever or weakness in tick-endemic areas
Inform your vet of any travel history when presenting a sick dog
