Tick-borne diseases cause significant suffering in dogs including Lyme disease, ehrlichiosis, and Rocky Mountain spotted fever — preventive care dramatically reduces welfare impacts.
Tick-borne diseases cause genuine suffering through fever, joint pain, and systemic illness that can be severe and life-threatening. Dogs with Lyme disease experience lameness from joint inflammation, lethargy from systemic disease, and kidney complications in severe cases — all of which cause prolonged welfare compromise. The welfare-optimal approach is comprehensive prevention combining tick control products and Lyme vaccination in endemic areas. Dogs who develop tick-borne disease despite prevention require prompt veterinary attention and antibiotic treatment — delays allow progressive illness that is more difficult to treat and causes greater suffering.
