Fleas, ticks, mosquitoes and biting lice can quickly settle into an animal’s coat, even when it lives in a flat. With so many products available, choosing a flea and tick spot-on treatment for dogs and cats may seem straightforward. However, selecting the wrong species, weight category or application frequency can make the treatment unsuitable.
Here are the main criteria to check before buying a flea treatment for dogs, a tick treatment for dogs or a flea treatment for cats, along with a selection of spot-on treatments suited to different needs.
A spot-on treatment for dogs is not automatically suitable for cats. Some substances used in dog treatments can be highly toxic to cats, as stated in the product information for the Advantix products featured here. Never share a pipette between several animals, even if they are a similar weight.
The dosage must also match the animal’s actual weight. A dog spot-on treatment by weight may be intended for animals weighing 1.5 to 4 kg, 4 to 10 kg, 10 to 25 kg, 25 to 40 kg or 40 to 60 kg. For cats, the categories are generally divided either side of the 4 kg threshold.
The length of protection varies depending on the species and the parasite targeted. The Beaphar Fiprotec product information states up to 5 weeks’ protection against fleas and up to 4 weeks against ticks in dogs. For Advantage, the stated protection against fleas lasts from 3 to 4 weeks in cats, while it can last up to one week in rabbits.
These indications cannot be applied to all products or every situation. Before each application, check the label, leaflet and instructions for use.
A spot-on treatment treats the animal, but it does not remove the need to clean its bedding, carpets, baskets and other areas it regularly uses. In the event of an infestation, flea eggs and larvae can hide around the home. Regular cleaning helps prevent the problem from returning.
Start by checking which species are authorised: dog, cat or rabbit. The products featured here are not interchangeable. Also check the minimum age stated. For example, the Advantage products mentioned are intended for kittens from 8 weeks old, while the Advantix products for dogs can be used from 7 weeks old.
The spot-on treatment should only be applied to healthy skin. If the area is irritated, damaged or particularly sensitive, ask a vet for advice before use.
Fipronil is the active ingredient listed for the Beaphar Fiprotec products intended for dogs. Advantix products contain a combination of imidacloprid and permethrin. Their action is described as covering several external parasites: fleas, ticks, mosquitoes, sand flies, biting lice and stable flies.
Advantage for cats and rabbits contains imidacloprid. It is presented as a flea treatment, rather than as general protection against ticks. The right choice therefore depends on the parasite you need to treat, not just the brand name.
A spot-on treatment is applied directly to the skin by parting the fur between the shoulder blades. Some products require the solution to be distributed over several points. Do not massage the area if the instructions advise against it.
After application:
In the event of accidental ingestion, trembling, persistent redness or an unusual reaction, contact a vet promptly. Biocides must be used with care: always read the label before use.

The frequency depends on the product, the species and the parasite targeted. The products featured here generally call for application every four weeks, but the duration may differ for rabbits. Always follow the instructions for the product you have purchased rather than a generic schedule.
No. A spot-on treatment intended for dogs must never be applied to a cat, particularly when it contains permethrin. The Advantix product information states that this product is highly toxic to cats. Choose a cat spot-on treatment by weight, with a clear indication of the species it is intended for.
No. They are applied to the animal and do not replace cleaning the home. Wash suitable textiles, vacuum the areas your pet uses and follow the recommendations provided with the products you use. If the infestation continues or the animal develops an unusual reaction, ask a vet for advice.
