Flea and Tick Spot-On Treatments for Dogs in 2026: How to Choose the Right Treatment for Your Dog’s Weight

Flea and tick spot-on treatments for dogs are easy to use, but they do not all target the same parasites or suit every animal. An incorrect dosage, a misread label or incompatibility with another pet in the household can quickly turn an attractive deal into a wasted purchase.

Before choosing a parasite treatment for your dog, check three things: your companion’s exact weight, the parasites you want to target and the usage precautions. This selection of products available on Joybuy will help you make an informed choice and avoid the most common mistakes.

Common pitfalls when buying a spot-on treatment for your dog

1. Looking only at the box price

A pack of four pipettes is not necessarily more expensive than a pack of six: it all depends on the stated protection period. For example, the Beaphar Fiprotec product page indicates up to five weeks of protection against fleas and up to four weeks against ticks. The Advantix products featured here are generally designed for monthly application.

When comparing offers, it is therefore better to calculate the monthly cost of protection rather than looking only at the price displayed on the box.

2. Mistaking flea protection for full parasite coverage

Fipronil for dogs, used in Beaphar Fiprotec products, targets fleas and ticks according to the product information. Advantix products combine imidacloprid and permethrin to cover a broader range of external parasites: fleas, ticks, mosquitoes, sand flies, biting lice and stable flies.

A dog flea treatment does not necessarily protect against the same parasites as a dog tick treatment. Before placing your order, check the exact list shown on the packaging.

3. Forgetting to check the weight category

Dosages are not interchangeable. A pipette designed for a small dog must not be used on a larger dog, and a pipette intended for another weight category should never be split. Weigh your dog before buying, particularly if they are still growing or close to the limit between two formats.

If you are unsure, ask a vet or pharmacist for advice and follow the instructions for the product authorised for use in France.

What to check before buying

Weight, age and skin condition

The products featured here are not suitable for the youngest puppies. Beaphar Fiprotec products are indicated for dogs from 8 weeks of age, with specific weight categories for each format. Advantix products are indicated from 7 weeks of age, again with different thresholds depending on the version.

Always apply the pipette to healthy, visible skin. The product must reach the skin rather than simply coat the fur. If your dog has a skin condition, reacts to certain ingredients or is already receiving an antiparasitic treatment, it is best to seek professional advice before applying anything.

Active ingredients and targeted parasites

The selected Beaphar Fiprotec products contain fipronil. They are available for dogs weighing 2–10 kg, 10–20 kg and 20–40 kg.

Advantix products combine imidacloprid and permethrin. According to the supplied product information, they are available for dogs weighing 1.5–4 kg, 4–10 kg, 10–25 kg, 25–40 kg and 40–60 kg. They may therefore be worth considering when the aim is to cover several external parasites.

Please note: the Advantix products featured here are highly toxic to cats. If you have a cat at home, prevent them from touching the application site until the product has dried completely, and read the instructions carefully.

Protection period and usage precautions

To maintain continuous protection, application is generally carried out once a month. However, the exact duration varies according to the product and the targeted parasite. For Advantix, the product information recommends avoiding bathing for 48 hours before and after application. The product is described as resistant to moderate exposure to water, but this does not mean it will withstand repeated swimming without any impact.

After application, wash your hands and avoid contact with your eyes and mouth. Children and other animals must not touch the treated area until it is completely dry.

How to apply a parasite treatment pipette

  1. Check your dog’s weight and age, and read the product instructions.
  2. Open the pipette without piercing it with your teeth.
  3. Part the fur between the shoulder blades until you can see the skin.
  4. Apply the solution directly to the skin, following the specified number of application points.
  5. Do not touch the treated area until it has dried completely, then wash your hands.

Never apply a product intended for dogs to a cat. In the event of ingestion, severe irritation, trembling or unusual behaviour, contact a vet promptly.

Frequently asked questions

Which pipette should I choose for a 6 kg dog?

Choose a category that specifically includes 6 kg, such as a pipette for dogs weighing 2 to 10 kg or 4 to 10 kg, depending on the product. Then compare the parasites covered and the active ingredients.

How long does a flea and tick pipette last?

It depends on the product and the targeted parasite. Beaphar Fiprotec product pages state up to five weeks of protection against fleas and four weeks against ticks. The Advantix products featured here are designed for monthly application. In all cases, the instructions and label of the product purchased take precedence.

Can I bathe my dog after application?

For the Advantix products mentioned here, it is recommended to avoid bathing for 48 hours before and after application. For other treatments, follow the instructions in their package leaflet. Frequent bathing may also reduce how well the product remains on the coat.
