Flea and tick spot-ons for dogs: our 2026 selection by weight

Flea and tick spot-ons for dogs are easy to apply, but choosing the right product is about more than the number of doses in the box. An insufficient dose, the wrong weight category or incorrect application can reduce the effectiveness of the parasite treatment and leave you wasting money.

Before placing your order, check the minimum age requirement, your dog’s actual weight, the parasites targeted and the precautions stated on the label. Here are the most common mistakes to avoid, followed by a selection of products available on Joybuy.

Common pitfalls when buying

1. Confusing pipette volume with the appropriate dosage

A 2.5 ml pipette is not necessarily suitable for every medium-sized dog. The volume and amount of active ingredients vary according to the weight category. For example, Advantix Medium Dog 10–25 kg contains 250 mg of imidacloprid and 1,250 mg of permethrin per pipette, compared with 600 mg of imidacloprid and 3,000 mg of permethrin for the version intended for dogs weighing 40–60 kg.

Never split a pipette between several dogs, and do not choose a product simply because it is “close” to your pet’s weight. Use your dog’s current weight rather than an estimate from several months ago.

2. Relying solely on the stated protection period

The protection period varies according to the product and the parasite targeted. In the Advantix range featured here, the stated protection is approximately four weeks against several external parasites. Beaphar Fiprotec, meanwhile, states up to five weeks against fleas and four weeks against ticks, according to the product information provided.

These periods correspond to the information supplied for each product. Always read the French instructions and label before application, particularly if your dog swims frequently or an infestation is already present.

3. Forgetting which parasites are targeted

A flea spot-on for dogs does not necessarily cover the same parasites as a tick spot-on. Some fipronil-based formulas mainly target fleas and ticks. The combination of imidacloprid and permethrin used by Advantix is also presented as effective against mosquitoes, sandflies, biting lice and stable flies.

If you live in the south of France, travel with your dog or regularly visit wooded areas, check the precise list of parasites covered. The product name alone is not enough to help you choose.

What to check before buying

Weight and minimum age

Weight is the first criterion to consider when choosing a parasite treatment for your dog. The products available cover the following categories in particular:

  • 1.5 to 4 kg: small dog or puppy meeting the stated minimum age;
  • 4 to 10 kg;
  • 10 to 25 kg;
  • 25 to 40 kg;
  • 40 to 60 kg.

The Advantix products featured in this selection must not be used on puppies under seven weeks old or weighing less than 1.5 kg. The Beaphar Fiprotec products supplied state that they can be used from eight weeks of age, with weight thresholds varying according to the model.

In the event of rapid growth, weight loss or uncertainty between two categories, ask a vet or pharmacist for advice.

Active ingredient and scope of action

Fipronil is present in the Beaphar Fiprotec products. The product information states 67 mg for the 20–40 kg version and 268 mg for a 2.68 ml pipette in the same category, depending on the detailed presentation. Always check the labelling of the product you receive, as formats may vary.

The Advantix products are based on imidacloprid and permethrin. The product information describes contact action and a repellent effect against several external parasites, with spot-on application directly to the skin. This information should be considered alongside the instructions, your dog’s lifestyle and professional advice.

Pack size and monthly cost

A pack of six pipettes generally covers several monthly applications, while a pack of four can reduce the number of orders you need to place during the year. To compare offers, look at the price per pipette rather than just the box price.

If you apply the treatment every month, record each dose in your calendar. For the Advantix products featured here, avoid bathing your dog for 48 hours before and after application. The product must be applied to healthy skin, directly between the shoulder blades or in accordance with the instructions.

Spot-on application: essential precautions

  1. Part the fur until the skin is visible, then apply the contents directly to a healthy area.
  2. Avoid the eyes, mouth, irritated areas and any risk of licking.
  3. Wash your hands thoroughly after application. Do not allow children or other animals to touch the treated area until it is dry.
  4. Never use a product containing permethrin on a cat: the Advantix product information warns that it is highly toxic to this species.
  5. If you are pregnant or may be pregnant, wear gloves when handling the product, in accordance with the stated precautions.
  6. In the event of accidental ingestion, persistent irritation or an unusual reaction, contact a vet promptly.

The pipettes are for animal use only. Follow the regulations and labelling applicable in France, as well as professional advice for a puppy, a pregnant dog, an ill animal or a household with several species.

Frequently asked questions about flea and tick spot-ons for dogs

How often should a parasite spot-on be applied?

It depends on the product used. The product information featured generally states that Advantix and Beaphar Fiprotec should be applied every four weeks, with variations depending on the parasite targeted. Check the instructions before renewing the treatment.

Does one pipette protect against all external parasites?

No. Some formulas mainly target fleas and ticks, while others also claim to be effective against mosquitoes, sandflies, biting lice or stable flies. Check the list of parasites covered on the packaging.

How much does monthly protection for a dog cost?

To estimate this, divide the price of the pack by the number of usable pipettes, then take into account the stated protection period for each parasite. A pack of six can reduce the number of orders you need to place, but your dog’s weight and the formula remain more important than the simple unit price.
