Ticks on dogs: essential facts to keep your
dog safe

Ticks can cause serious and potentially fatal diseases in dogs. Read on to find out everything you need to know about ticks on dogs and how to keep your dog safe.

When you own a pet, the last thing you want is for them to be bitten by ticks. They are common parasites of dogs and cats around the world, and Australia is no different. There are different types of ticks on dogs, and depending on the tick species, they can cause deadly tick paralysis or transmit other harmful and life-threatening diseases. 

As a dog owner, you need to know what to do to protect your dog against ticks, and what to do if your dog gets a tick. Take a look at how to identify ticks on dogs and what to do if you find a tick on your dog. 

What do Dog Ticks Look Like?

Ticks on dogs tend to be about the size of an apple seed when they have not fed, and can vary in colour, depending on the species. After they take a blood meal from their host, ticks become ‘engorged’. When this happens, they can be as big as your little fingernail. Not all ticks look the same, and ticks tend to look different throughout their lifecycle, so if you’re not sure if it’s a tick, it’s best to consult with your vet. 

The Types of Ticks on Dogs

There are three main tick species that infest dogs in Australia: paralysis ticks, brown dog ticks, and bush ticks. 

• Paralysis Ticks: Paralysis ticks are typically found along the east coast of Australia, from Cape York in the north, all the way down to Lakes Entrance in Victoria. They are occasionally seen outside this area (e.g. the greater Melbourne area). They are one of the most dangerous parasites that can affect your pet as they produce a toxin which causes tick paralysis in dogs and cats. 

• Brown dog ticks: The brown dog tick is widely distributed throughout Australia. Although these brown ticks cannot cause paralysis, they can cause skin irritation and heavy infestations may result in anaemia from excessive blood loss. Brown dog ticks can also transmit potentially fatal infections from one dog to another. Ehrlichia canis is one such bacteria that is transmitted by brown dog ticks.  This potentially fatal brown dog tick disease was identified for the first time in Australia in 2020.

• Bush tick: Australia is home to bush ticks which are found along parts of the east and west coast. If you find a bush tick on your dog, it is important to remove it.  Bush ticks can cause skin irritation and can also transmit potentially fatal diseases when they bite (e.g. babesiosis).

How to Find Ticks on Dogs 

If you are trying to find a tick on your dog, first check for signs of itching and look at the site where your dog is scratching. Another sign your dog has a tick is if it yelps or winces when patted. The tick may be causing it to feel sensitive where it has latched on. 
A thorough check of your dog can also help you find ticks. Run your fingers over them, parting their fur around their neck, ears and tail. If you feel a very small bump, it could be a tick. 

How do Dogs Get Ticks?

Dogs get ticks from the great outdoors. Ticks ‘quest’ to find a host, which includes crawling up low grass or shrubs and lying in wait. Ticks are sensitive to heat and the carbon dioxide that your dog exhales, which alerts them that there’s a suitable host nearby. When your pet pooch brushes past on a walk or while playing outside, the tick uses its front legs to grab on, then crawls over the coat and through the fur to find a suitable place to attach and feed.
Ticks can be a problem all year round in Australia, but the highest risk is in spring and summer. 

The Problems Ticks Cause in Dogs

As mentioned above, there are different types of ticks on dogs. Depending on the tick species, they can cause deadly tick paralysis or transmit other harmful and potentially fatal diseases to dogs. At the very least, a tick bite may cause irritation where it attaches to your dog. 

The Symptoms of Ticks on Dogs

Tick bite symptoms in dogs vary depending on the type of tick involved. 
Brown dog tick symptoms may include irritation of the skin or anaemia, while for paralysis tick symptoms, you may notice one or more of the following signs (It usually takes three days or more after a paralysis tick attaches before signs develop): 

• A loss of coordination in the hind legs (wobbly or not being able to get up) which may progress to paralysis.
• A change in voice or bark.
• You may notice your dog vomiting after a tick bite.
• Retching, coughing or loss of appetite.
• Laboured breathing or rapid breathing.
• You may notice that your dog is lethargic after a tick bite.

Can Humans Catch Ticks From Dogs?

Humans can also be bitten by ticks, but they are usually picked up from walking through vegetation and not from our pets. 
It is uncommon to see tick paralysis in humans, but when it does occur, young children are more commonly affected. Bites from paralysis ticks may trigger the development of mammalian meat allergy in humans.

How to Remove a Tick From a Dog

You may be wondering how to get rid of ticks on dogs. If you find a tick on your dog it should be removed as soon as possible. Please see the instructions below for how to remove a tick from a dog.

• Tweezers can be used to remove a tick from a dog that’s embedded into its skin. Grab the tick adjacent to your dog’s skin (at the tick mouthparts), twist the tick, then pluck the tick away from the skin. Take care not to squeeze the tick’s body. If you want to remove a tick from a dog without tweezers, you can also purchase a tick removal tool, like a tick hook, from your local vet and follow the instructions on the packaging.
• After removal, store the tick in a sealed container for identification by your veterinarian.
• It is possible for a dog to develop signs of tick paralysis even after a tick has been removed, so it is recommended to keep a close eye on your dog for a few days. If you have any concerns about your dog’s health you should seek immediate veterinary attention.

How to Prevent Ticks on Dogs 

Unfortunately, if your dog likes to spend time outdoors, there’s no way to prevent contact with ticks. But you can help protect against ticks by checking your dog daily and using a proven tick treatment like NexGard® or NexGard SPECTRA®. Just one monthly chew provides effective control of pre-existing paralysis ticks within 24 hours and provides protection for a full month against paralysis ticks, brown dog ticks and bush ticks.
Although tick control products will control most of the ticks that your pet may be exposed to, it only takes one tick to cause tick paralysis. For this reason, it is important to also perform daily tick searches on your pet. If you live in, or you and your pet are visiting a known tick area, it is recommended to search your pet daily for ticks and tick craters (scabby, circular skin lesions where a tick was previously attached).

Ticks on dogs FAQ

Take a look at the answers to some of the most commonly asked questions about ticks on dogs:

• What should I do if my dog has ticks?

If you find ticks on your dog they should be removed as soon as possible and you should contact your veterinarian for advice. 

• Should I take my dog to the vet for a tick?

You should contact your veterinarian for advice. If your dog is living in, or has travelled to, a known paralysis tick region, contact your veterinarian and take your pet to the clinic as soon as possible. If you find a tick and no clinical signs of tick paralysis are observed, it is still recommended to consult your veterinarian as signs of tick paralysis can develop even after the tick has been removed.

• How do you remove a tick from a dog?

Use tweezers or a tick removal tool, like a tick hook, to remove the tick. Grab the tick adjacent to your pet’s skin (at the tick mouthparts), twist the tick, then pluck the tick away from the skin. Take care not to squeeze the tick’s body. 

• How big can ticks get on dogs?

Before feeding, ticks are small and only a few millimeters in size. After attaching and feeding on a dog’s blood, fully engorged ticks can grow to more than 1 cm in size. 

• How do you find ticks on black dogs?

Regardless of the colour of your dog, to find ticks it is recommended to walk your fingers through your dog's coat, feeling the skin surface carefully as you go. Pay particular attention to those hidden or hard to reach areas like under the collar and chin, between the toes, the paws, gum-line, lips, eyes and inside the ears. And don’t forget to feel along their body, making sure to check their belly, and then down their back legs and genital region, as ticks can be found there, as well as on the tail. Consider keeping your dog’s coat shorter in the spring so you can spot ticks more easily.  

• How can you tell if a tick head is still in the dog?

Sometime the mouthparts of the tick are left in the skin after tick removal. This appears like a dark spot in the skin. Don’t attempt to remove this yourself. It is always advisable to speak to your vet, who may ask you to bring your dog to the clinic to be checked-over.

• What happens if the head of the tick stays in the dog?

If the mouthparts of the tick are left in they are unlikely to cause a problem, however you should speak with your veterinarian for advice. Never dig around in the skin in the attempt to remove them yourself. 

• What do I do with my dog’s skin after removal?

After removal of a tick, the skin will usually heal well on its own. You should still contact your veterinarian for advice, especially if you live in a known paralysis tick region, as signs of tick paralysis can develop even after the tick has been removed.

• How do I pull a tick from a dog?

Use tweezers or a tick removal tool, like a tick hook, to remove the tick. Grab the tick adjacent to your pet’s skin (at the tick mouthparts), twist the tick, then pluck the tick away from the skin. Take care not to squeeze the tick’s body. 

• How do I get rid of small ticks on dogs?

Use tweezers or a tick removal tool, like a tick hook, to remove the tick. Grab the tick adjacent to your pet’s skin (at the tick mouthparts), twist the tick, then pluck the tick away from the skin. Take care not to squeeze the tick’s body.

Use tweezers or a tick removal tool, like a tick hook, to remove the tick. Grab the tick adjacent to your pet’s skin (at the tick mouthparts), twist the tick, then pluck the tick away from the skin. Take care not to squeeze the tick’s body. 

• How do puppies get ticks?

As with older dogs, puppies can pick up ticks when they are outdoors. Ticks carry out what is called ‘questing behaviour’, crawling up low grass or shrubs and lying in wait. When your puppy brushes past on a walk or while playing outside, the tick uses its front legs to grab on, and then crawl over the skin, through the fur to find a suitable place to attach and feed.
