Some medical conditions are both common and easily overlooked—like anemia. In most cases, anemia may not seem particularly severe, often manageable with regular meals and a balanced diet.
But sometimes, it could signal a hidden danger…

The Hidden Killer in the Blood
Babesia, also known as piroplasm, is a type of protozoan parasite belonging to the order Piroplasmida.
It is a collective term for parasites that invade the red blood cells of mammals.
Transmission:
Primarily spread through tick bites, though blood transfusions and vertical transmission (mother to offspring) may also occur.
This disease is widespread globally, found in many countries.
In dogs, the primary pathogens include Babesia canis, B. vogeli, B. gibsoni, and B. microti. Among these, Babesia canis and B. gibsoni are the most clinically common.
Infected dogs may exhibit symptoms such as fever, lymphadenomegaly, liver dysfunction, and more.
Some dogs may develop symptoms gradually, showing only mild mucosal pallor and lethargy initially, which progressively worsen. Others may experience acute onset, potentially leading to systemic inflammatory response syndrome, multiple organ failure, or even death.
The common hallmark, however, is hemolytic anemia.
These parasites inhabit and destroy red blood cells, causing hemolysis and severe anemia. Affected dogs may display reduced appetite, dark-colored urine (brown or tea-colored in severe cases), jaundice, and other symptoms. Pet parents must remain vigilant!
Causes and Prevention
All types of Babesia parasites are transmitted through tick bites—yes, this troublemaker again. (check here Holistic flea and tick prevention for dogs)
Summer and autumn are typically high-risk seasons for babesiosis, but in warmer regions, caution is advised year-round.
Diagnosis usually relies on blood smear examination. However, this method is less effective for detecting Babesia gibsoni. Sometimes multiple tests are needed for confirmation. PCR testing is more sensitive, but it’s generally only available at university-affiliated veterinary hospitals with research capabilities. Consequently, chronic or atypical cases in dogs often face delayed treatment.
For confirmed cases, treatment typically involves antiprotozoal drugs (e.g., diminazene aceturate), antibiotics, and supportive care. However, many veterinary clinics only stock diminazene aceturate, which works for Babesia canis but is ineffective against Babesia gibsoni. Severe cases may require blood transfusions.
While babesiosis isn’t always fatal, infected dogs endure significant suffering, face high mortality risks, and impose heavy financial burdens on owners.
The Ultimate Prevention?
Deworming! Deworming! And Deworming Again!
The key to preventing babesiosis is tick control. Most topical dewormers are effective, but always:
- Purchase from reputable sources.
- Use under veterinary guidance.
- Check drug labels for safety in Collies—ensure they don’t state “Contraindicated for Collie breeds.”
