Common Tick-Borne Diseases in Dogs: A Persistent Health Risk


Dec 15,2025


Tick-borne diseases remain an important and often underestimated health concern in dogs. Due to their insidious onset and diverse clinical manifestations, these infections can be easily overlooked in daily practice. Delayed diagnosis may lead to disease progression, chronic complications, and increased treatment challenges. Improving awareness and strengthening diagnostic strategies are essential for effective canine health management.

 

Common Tick-Borne Diseases in Dogs

Several tick-transmitted pathogens are frequently encountered in canine clinical cases:

Canine Ehrlichiosis
Caused by Ehrlichia species, this disease may present with fever, lethargy, reduced appetite, and bleeding tendencies. Chronic infections can result in immunosuppression and long-term health issues.

Canine Babesiosis
A hemoprotozoan disease that invades red blood cells, leading to hemolytic anemia. Clinical signs may include pale mucous membranes, jaundice, dark-colored urine, and weakness. Severe cases can be life-threatening.

Lyme Disease
Triggered by infection with Borrelia burgdorferi, Lyme disease in dogs is commonly associated with intermittent lameness, joint pain, and fever. In some cases, renal complications may develop.

Canine Anaplasmosis
Often showing clinical signs similar to ehrlichiosis, anaplasmosis is frequently involved in co-infections, further complicating diagnosis and treatment decisions.

 

Diagnostic Challenges

One of the main challenges in managing canine tick-borne diseases is the lack of specific early-stage clinical signs. Co-infections, subclinical cases, and variable immune responses make diagnosis based on clinical presentation alone unreliable, increasing the risk of missed or delayed detection.

 

The Importance of Early and Targeted Testing

When dogs present with unexplained fever, anemia, lameness, or general weakness—especially with a history of possible tick exposure—tick-borne diseases should be included in the differential diagnosis.
Rapid and reliable diagnostic testing can provide valuable information within a short timeframe, supporting timely clinical decisions and appropriate treatment planning.

 

Recommendations for Canine Health Management

Maintain consistent ectoparasite prevention programs

Regularly monitor dogs for changes in health status

Include tick-borne diseases in diagnostic considerations for non-specific clinical cases

Implement follow-up testing when necessary to monitor disease progression or treatment response

 

Conclusion

Tick-borne diseases represent an ongoing risk to canine health. Through increased awareness, proactive prevention, and the use of effective diagnostic tools, veterinarians and animal care professionals can reduce the impact of these infections and support better long-term health outcomes for dogs.
