Ticks and Fleas in Dogs – Why Prevention Lasts All Year

Do ticks and fleas only attack dogs in summer

Ticks and fleas attack dogs all year round, not just in spring and summer – at temperatures as low as 5–7°C, ticks wake from hibernation and start looking for a host. Parasite protection should therefore run uninterrupted, including in autumn and winter.

Available forms of protection include spot-on treatments applied every 4 weeks, collars that work for several months, and tablets dosed by the dog's weight – the choice is best discussed with a vet, since it depends on the region and the animal's lifestyle. Ticks carry dangerous diseases like Lyme disease and babesiosis, so a gap in protection genuinely increases the risk of infection.

How to protect a dog against ticks and fleas all year round

Here are the key rules for effective prevention:

• Uninterrupted protection, even in winter – mild winters mean ticks can stay active nearly year-round.
• Regularly renewing the product – spot-on treatments every 4 weeks, collars according to the manufacturer's stated duration.
• Checking the coat after every walk – especially around the ears, under the collar, and between the toes.
• Matching the product to the dog's lifestyle – a dog that regularly visits forests and parks needs stronger protection than one that only walks around the city.
• Consulting a vet when choosing a method – dosage and product type depend on weight, age and region.

Why a gap in prevention is riskier than it seems

Many owners stop using tick and flea products at the end of summer, treating it as the natural end of the "season" – in practice, ticks in many regions increasingly stay active into autumn and on mild winter days too. Ticks can slow their metabolism and enter a state resembling hibernation, but it only takes a short spell of warmer weather for them to wake up and start looking for a host.

The risk isn't limited to the bite itself – ticks carry diseases that can develop over weeks before visible symptoms appear in a dog. That's why a gap in prevention doesn't just mean risk "at that particular moment," but an extended window of vulnerability that's hard to reverse once infection has occurred. Consistency of protection matters more here than the choice of a specific product.

Forest dog, city dog or traveling dog – how to match protection

If your dog regularly walks through forests and tall grass, it needs stronger and more consistent protection than a dog that mostly walks on sidewalks and city parks.

If you live in a region with mild winters, it's worth continuing prevention all year round – if winters in your region are cold and long, the risk of tick activity in winter is lower, but not zero.

If you're traveling with your dog to another country or region, check local risks (such as other tick-borne diseases) and adjust prevention before the trip.

If there's more than one dog at home, it's worth setting a shared schedule for applying products, so dates don't get mixed up and no dog is left unprotected.

The most common mistakes in tick and flea prevention

Stopping protection after summer is the most common mistake – ticks tend to stay active far longer than the "traditional season" assumes.

Another mistake is not tracking reapplication dates – spot-on treatments and tablets have a limited duration, after which protection weakens.

A frequent mistake is also checking a dog's coat only "from time to time," rather than after every walk in tall grass or forest areas.

The last mistake: choosing a product based on price rather than the dog's lifestyle and the risks typical of the region you live in.

FAQ – frequently asked questions about ticks and fleas in dogs

Do ticks attack dogs in winter too?

Ticks can attack dogs in winter too, if the temperature rises to 5–7°C – mild winters mean they can stay active almost all year round.

How often should you apply tick and flea spot-on treatment?

Tick and flea spot-on treatment is typically applied every 4 weeks, though the exact interval depends on the specific product and is worth checking with a vet.

What diseases do ticks carry in dogs?

Ticks can carry dangerous diseases such as Lyme disease and babesiosis, which sometimes develop over weeks before visible symptoms appear.

Is a tick collar enough protection on its own?

A tick collar can be an effective form of protection, but its choice and duration are worth verifying with a vet, especially for dogs that spend a lot of time in forests.

How can you check if a dog has a tick?

After a walk, it's worth checking the coat by touch, paying attention to the ears, the area around the collar, and the spaces between the toes, where ticks most often attach.

What matters more than the choice of product?

Tick and flea prevention works best when it runs uninterrupted all year round, not just during the traditionally understood season. Consistency of application matters more than the specific type of product. The specific product and its dosage should, however, be chosen by a vet, since they depend on weight, age, species and health.
