What does a tick threaten a dog with? - briefly

Ticks can transmit bacterial, viral, and protozoal pathogens such as Lyme disease, ehrlichiosis, and babesiosis, causing systemic infection and anemia. They also induce local skin inflammation, itching, and possible allergic reactions.

What does a tick threaten a dog with? - in detail

Ticks attach to canine skin to obtain blood, creating a portal for pathogens and toxins. The primary hazards include infectious diseases, immune reactions, and physical damage.

Infectious agents transmitted by ticks:

  • Borrelia burgdorferi, the bacterium responsible for Lyme disease; symptoms may involve fever, joint swelling, lameness, and renal complications.
  • Ehrlichia canis and Ehrlichia chaffeensis, causing canine ehrlichiosis; clinical signs feature thrombocytopenia, anemia, fever, and weight loss.
  • Anaplasma phagocytophilum, leading to anaplasmosis; dogs often display fever, lethargy, and musculoskeletal pain.
  • Babesia spp., producing babesiosis; results in hemolytic anemia, jaundice, and possible organ failure.
  • Rickettsia rickettsii, the agent of Rocky Mountain spotted fever; manifestations include fever, skin eruptions, and vascular damage.
  • Tick‑borne encephalitis virus, rare in dogs but capable of inducing neurologic signs such as ataxia and seizures.

Non‑infectious threats:

  • Tick paralysis caused by neurotoxins secreted in the tick’s saliva; onset includes progressive weakness, loss of coordination, and potential respiratory failure if the tick remains attached.
  • Localized skin irritation, erythema, and ulceration at the bite site; secondary bacterial infection may develop, leading to pus formation and tissue necrosis.
  • Acute blood loss in heavy infestations, producing anemia and reduced performance.

Prevention strategies focus on regular inspection, use of acaricidal collars or spot‑on products, and environmental control of tick habitats. Prompt removal of attached ticks, using fine‑tipped tweezers to grasp the mouthparts close to the skin and pulling steadily, reduces the chance of pathogen transmission. Veterinary evaluation is essential when any of the listed signs appear, enabling diagnosis through serology, PCR, or blood smear and initiating appropriate antimicrobial or supportive therapy.
