Flea and tick spot-on treatments for dogs meet a simple need: protecting your pet with a practical application, without the hassle of extra accessories. But getting the weight, age or active ingredient wrong can make the treatment unsuitable. Before ordering a parasite treatment for your dog, carefully check the information on the packaging and in the leaflet.
The weight range is the first thing to check. A dog weighing 8 kg, 18 kg or 35 kg won’t necessarily need the same concentration or volume. Products are usually split into categories: 1.5–4 kg, 2–10 kg, 4–10 kg, 10–20 kg, 10–25 kg, 20–40 kg, 25–40 kg or 40–60 kg.
Weigh your dog recently, especially if it’s still a puppy. Don’t combine several spot-on treatments meant for a different weight range without consulting a vet or carefully checking the leaflet.
The phrase ‘monthly protection for your dog’ doesn’t necessarily mean the treatment lasts the same length of time against every parasite. For example, the Beaphar Fiprotec product page states up to 5 weeks against fleas and up to 4 weeks against ticks. So you should always follow the application frequency given for the specific product you choose.
How well a flea and tick treatment works can also vary depending on exposure levels, whether you have other pets, and your home environment. Remember to wash your dog’s bedding regularly and check their coat after walks.
Some products target fleas and ticks, while others also cover mosquitoes, sandflies, biting lice or stable flies, according to their product pages. A broader-spectrum product might be suitable for a dog that travels, lives near a rural area, or goes outside very often. However, you should always check the precautions for its active ingredients.
For the products shown here, the minimum age is usually 7 or 8 weeks, depending on the product. Some treatments aren’t suitable for dogs under 1.5 kg or 2 kg. Also check that the product is definitely intended for dogs.
Products containing permethrin – including several Advantix treatments for dogs – must not be used on cats: the product page describes them as highly toxic to cats. If you have a cat at home, keep the animals apart until the treated area is completely dry, and follow the leaflet instructions carefully.
Beaphar Fiprotec contains fipronil and mainly targets fleas and ticks, with formats available for several weight ranges. The Advantix products shown combine imidacloprid and permethrin and are indicated, according to their product pages, against six external parasites: fleas, ticks, mosquitoes, sandflies, biting lice and stable flies.
This information describes the composition and intended use as stated by the manufacturer. It does not replace the advice of a vet, especially for puppies, pregnant or nursing females, or animals that are ill or have sensitive skin.
The number of pipettes directly affects the monthly cost. A pack of four pipettes usually covers several applications, while a pack of six can last longer if the leaflet recommends reapplication every four weeks.
Apply the liquid onto the skin, not just onto the fur, between the shoulder blades or at the spots indicated. The skin must be healthy. For several Advantix products, it’s recommended to avoid bathing your dog for 48 hours before and after application. Even if a product can withstand moderate exposure to water, that doesn’t mean it’s suitable for repeated swimming or immersion straight after application.
Why this suits this profile: This format is ideal for owners looking for a flea and tick spot-on treatment for dogs with a dosage clearly matched to animals weighing 2 to 10 kg, with four applications in the pack.
The weight range and volume of 0.67 ml per pipette are clearly stated, reducing the risk of choosing a format that’s too concentrated.
Contains fipronil, as stated on the product page, four pipettes and direct skin application.
Why this suits this profile: This format is designed for very large dogs and households looking for protection that’s claimed against several external parasites, including mosquitoes.
The weight range of 40 to 60 kg is explicitly stated, so you won’t use a dosage meant for a smaller dog.
Each pipette contains 6 ml, with monthly application and a spectrum of six parasites as stated on the product page.
Why this suits this profile: The pack of six pipettes is ideal for owners who want to plan several monthly applications for a medium-sized dog.
The 10–25 kg format and volume of 2.5 ml per pipette are clearly stated, making it easy to check before ordering.
Six pipettes, application onto healthy skin, and indicated for fleas, ticks and several external insects.
Why this suits this profile: This product is aimed at very small dogs and owners who want to match their pet’s actual weight to the dosage precisely.
The 1.5 to 4 kg range is clearly defined, with a restriction for puppies under 7 weeks old.
A 0.4 ml pipette, a pack of four, and monthly reapplication as stated on the product page.
We’ve put together a full list, updated in real time, of products that meet these strict selection criteria and European safety regulations.
The frequency depends on the product. Several Advantix products recommend monthly application, while Beaphar Fiprotec claims up to five weeks against fleas and four weeks against ticks. Always follow the interval stated in the leaflet.
Some products, like the Advantix treatments shown here, claim to work against mosquitoes and other external parasites. Beaphar Fiprotec mainly targets fleas and ticks. Check the exact spectrum before you buy.
Divide the price of the pack by the number of pipettes, then take into account the application interval stated. A pack of six isn’t necessarily better value if your dog’s weight needs a different product, or if the duration of action varies depending on the parasite.
