Dog Tick-Borne Disease: Prevention and Welfare

Tick-borne diseases including Lyme disease, babesiosis, and ehrlichiosis pose serious welfare risks to dogs, with prevention requiring consistent parasite control and owner vigilance.

Key Facts

Lyme disease (Borrelia burgdorferi) causes lameness, fever, and potentially fatal nephropathy in dogs
Babesiosis destroys red blood cells and can be rapidly fatal without treatment
Ehrlichiosis presents with thrombocytopenia, anaemia, and multi-organ effects
Tick attachment of 24-48 hours is typically needed for Borrelia transmission — prompt removal matters
Climate change is expanding tick habitat ranges, increasing disease risk in previously safe areas

Welfare Considerations

Tick-borne diseases cause significant suffering: joint pain and lethargy in Lyme disease, severe anaemia and weakness in babesiosis, and multi-system inflammation in ehrlichiosis. Early detection dramatically improves outcomes. Monthly or long-acting tick preventives (isoxazolines, collars) reduce attachment risk. Dogs in tick-endemic areas should be checked after every outdoor excursion. Annual testing for tick-borne diseases is recommended in high-risk regions. Owners who discontinue preventives due to cost or perceived low risk create preventable suffering. Vets should proactively counsel on regional tick disease risks and appropriate prevention strategies.

What You Can Do

Use vet-recommended tick prevention year-round, especially in woodland and grassland areas
Check your dog for ticks after every walk and remove any found with a tick hook within 24 hours
Ask your vet about annual tick disease screening if you live in an endemic area
