Questions about ticks

Where do we find paralysis ticks?

The paralysis tick is found on the eastern seaboard, from North Queensland to Victoria. In the northern parts of Australia, paralysis ticks may be found all year round, while in the more southern areas the season can begin in late winter and finish in late autumn. They are not always restricted to the immediate coastline and can be found inland in suitable habitats.

Paralysis ticks are found on animals that live in or near bush or scrubland. Native animals such as marsupials, birds and reptiles are the natural hosts. However, ticks can also become attached to and affect dogs and cats.

How does the tick cause toxicity?

The tick sucks blood from the host animal and, in doing so, secretes saliva that contains toxins which are absorbed and cause signs of paralysis and poisoning. Older dogs are at slightly higher risk of developing tick toxicity, but dogs of any age can be affected.

How do I identify the paralysis tick?

Once on the animal, the tick finds a site of attachment where it becomes deeply and firmly embedded in the skin. When an adult tick feeds on blood, it increases in size dramatically. When a tick attaches to the skin, the area becomes red and a raised thickening or 'crater' may appear. A "crater" is evidence of a prior tick attachment.

        

How do I check for ticks?

It is essential that after each outing you carefully examine your dog's coat and skin for any ticks. Make sure you check the skin folds of the body, inside the ear flaps and between the toes. Check the head and neck particularly well.

What are the symptoms of tick toxicity?

If your dog lives in or visits a high risk area for paralysis ticks, it is important to look out for the symptoms of toxicity. The symptoms to watch for are:

• Loss of coordination in the hindlegs (wobbly or not being able to get up).
• Change in voice or bark.
• Retching, coughing or vomiting.
• Loss of appetite.
• Progressive paralysis starting in the hindlegs and progressing to include the forelegs.
• Difficulty breathing or rapid breathing.

Not all cases follow a simple progression and the animal can die suddenly in the very early stages of paralysis.

What do I do if my dog shows the symptoms of tick toxicity?

• Keep your dog calm and at a comfortable temperature (not too hot or cold) and take it to the veterinarian.
• Do not offer food or water, as this may lead to pneumonia and breathing difficulties if your dog can't swallow properly.
• Seek veterinary attention as soon as possible.
• Search for a tick or ticks and remove them as soon as possible.
