Tick-borne diseases in Australian dogs

Introduction

Ticks can cause paralysis and can also spread infections to dogs. Early action matters. Know the signs, remove any tick you find, and use proven prevention on schedule. This guide was prepared with input from our lead vet, Dr. Feargus McConnell, BVSc.

What tick-borne illness can look like

• Tiredness, low appetite, or fever

• Lameness or sore joints

• Pale gums or yellow tinge to the eyes

• Vomiting, weight loss, or swollen lymph nodes

• Breathing changes or weakness in the back legs
  Any sudden illness after time in a tick area is a vet visit now, even if you cannot find a tick.

Paralysis from tick toxin

In parts of Australia, tick toxin can affect nerves and muscles. Early signs include a change in bark, gagging, coughing, trouble swallowing, and wobbly back legs. Keep your dog calm and cool and seek urgent veterinary care.

Infections ticks can carry

Ticks can transmit blood-borne infections in some regions. Illness may start with vague signs such as fever and lethargy, then progress. Your vet will decide on tests and treatment. Do not wait for symptoms to worsen.

What to do if you find a tick

1. Part the coat and grip close to the skin with a tick tool or fine-tipped tweezers.

2. Lift straight out with steady pressure. Do not twist, squeeze, or apply chemicals.

3. Keep the tick in a sealed container for your vet.

4. Check your dog for more ticks, then monitor closely for 24–48 hours.

Prevention that works

• Use a proven tick product matched to weight, age, and lifestyle. Dose on time.

• Do daily hands-on searches in risk areas.

• Keep grass short and avoid heavy scrub when possible.
