Tick, a host of dangerous diseases for dogs

Ticks attach to your dog’s fur during outings in forests, parks, and garden. They are particularly active between 32°F and 68°F (between 0°C and 20°C). Ticks plant their rostrum on warm and moist parts of your pet’s skin to feed on blood. Through the tick’s bite, many severe and sometimes fatal diseases infect our pets.

Discover the danger ticks pose to dogs.

What is a tick?

First of all, a tick is a few millimeters long. It’s a mite that’s part of the spider family. It feeds on blood at every stage of its life (larva, nymph, and adult). It needs water but can go without feeding for months (diapause).

Secondly, it has a “rostrum”. This is a mouthpiece that allows it to attach to its host (animal, human) to feed on its blood. At each stage of its life, it needs this blood to develop and survive.

Lastly, it carries viruses, parasites, and bacteria, which it transmits 12 to 48 hours after latching onto its host. The transmission of these pathogens is very serious for our dogs, and sometimes irreversible.

Why is a tick a danger to dogs?

An adaptable parasite:

You can find ticks in both urban and countryside settings. In fact, they climb to tips of leaves and branches, and hang there waiting from heights of 6 inches to 3 feet (from 15 cm to 1 m) off the ground. They do this in any type of vegetation, as long as temperatures are to their liking. From their perch, they then drop onto a passing host.

On hot-weather days, they stay close to the ground in search of water. This allows them to easily sneak into your pet’s fur. As a result, they pose a danger year-round for dogs, active and sedentary, urban and rural.

A mite that’s hard to spot:

If you regularly inspect your dog’s fur, it is easy to spot an adult tick filled with blood. But in its larva or nymph stage, this isn’t as easy: it’s no bigger than a pinhead. Identifying it then becomes more difficult, but its bite is just as dangerous.

Smart little tip 💡 !

If you find a red, swollen bulge behind your dog’s ears, under the armpits, or in the groin, it may have been bitten by a tick. These are the lymph nodes of the dog’s immune system, and if they’re swollen it means the body is trying to fight off an infection. If there are additional symptoms such as lethargy, refusal to eat, and sudden limping, consult a vet quickly.

Tick: a host for many diseases that infect dogs:

When a tick has planted its rostrum onto its host, it injects saliva containing a coagulant that allows it to feed freely: the blood can’t clot. This saliva, not blood loss, is where parasites, bacteria, and viruses responsible for diseases are found, and the tick injects it into your pet’s bloodstream directl!

• Piroplasmosis due to a blood parasite (particularly severe).
• Ehrlichiosis and anaplasmosis (bacterial diseases).
• Lyme disease or borreliosis, sometimes with an incubation period of several months.

And less commonly, hepatozoonosis (tick ingestion) or transient paralysis, a reaction to toxins secreted by some ticks.
