Dogs, Ticks, and Lyme Disease: Welfare and Prevention

Tick-borne diseases pose serious welfare threats to dogs. Understanding transmission, prevention, and treatment protects both animal and human health.

Key Facts

Lyme disease, caused by Borrelia burgdorferi, is the most common tick-borne illness in North America and Europe.
Dogs in tick-endemic regions have seroprevalence rates of 5-15%, with many infections remaining subclinical.
Lyme nephritis — a severe kidney complication — is fatal in a high proportion of affected dogs.
Ticks must typically be attached for 24-48 hours before transmitting Lyme disease pathogens.
Year-round tick prevention is now recommended in many regions due to milder winters extending tick seasons.

Welfare Considerations

Lyme disease causes joint pain, lameness, fever, and fatigue in dogs, significantly reducing their quality of life. Tick attachment itself causes localized irritation and, in heavy infestations, anemia and tick paralysis. Dogs that spend time outdoors — particularly in woodland and grassland environments — face ongoing exposure risk. Welfare-conscious tick management combines regular checking, prompt removal, and veterinary-recommended preventatives. Delayed diagnosis and treatment leads to chronic disease and more significant suffering. Owner education is central to prevention.

What You Can Do

Use veterinary-recommended tick preventatives year-round, especially in endemic areas.
Check dogs thoroughly for ticks after every outdoor excursion, focusing on ears, groin, and paws.
Remove ticks promptly using proper tools — never twist or crush the tick body.
Vaccinate against Lyme disease if you live in a high-prevalence area — speak to your vet.
Advocate for tick surveillance programs and public education in your community.
