Dog Lyme Disease: Welfare Management in Endemic Regions

Lyme disease affects thousands of dogs in tick-endemic regions annually, causing chronic welfare harms from joint pain and kidney disease when inadequately prevented or treated.

Key Facts

Lyme disease caused by Borrelia burgdorferi bacteria transmitted by Ixodes ticks affects an estimated 250,000 dogs annually in the United States
Clinical signs include shifting-leg lameness, fever, reduced appetite, and rarely severe protein-losing nephropathy
Many infected dogs remain clinically asymptomatic but can progress to serious disease months to years after infection
Vaccination combined with tick prevention provides excellent welfare protection in endemic areas
Lyme nephropathy when it occurs causes severe irreversible kidney disease with poor prognosis

Welfare Considerations

Lyme disease causes welfare harms ranging from the pain of acute polyarthritis to the life-threatening severity of Lyme nephropathy. The insidious nature of some presentations where dogs show vague intermittent lameness for extended periods before diagnosis means many dogs suffer inadequately recognized pain. Prevention through vaccination and year-round tick control in endemic regions is highly effective. Early antibiotic treatment of confirmed Lyme disease before serious organ involvement prevents the most severe welfare outcomes.

What You Can Do

Vaccinate dogs against Lyme disease if you live in or visit tick-endemic regions
Use year-round tick prevention products appropriate for your region and dog size
Check dogs for ticks after outdoor activities and remove promptly to reduce transmission risk
Test dogs annually for tick-borne diseases in endemic areas to catch subclinical infections early
