Best flea and tick collar for canine leishmaniasis prevention
Canine leishmaniasis is a serious disease transmitted by the sandfly, a small mosquito-like insect found in many parts of southern Europe, especially in warm and humid areas. Prevention is essential, as there is no definitive cure and it can be life-threatening for your dog.
One of the most effective ways to reduce the risk of infection is by using a flea and tick collar specifically designed to repel sandflies. These collars release active ingredients that repel and, in some cases, kill the insect before it can transmit the disease. In this guide, we’ll explain the most recommended models on the market, how to use them correctly, and which mistakes to avoid to ensure maximum protection.

How a flea and tick collar helps prevent leishmaniasis
Leishmaniasis is transmitted when an infected sandfly bites a dog, injecting the Leishmania infantum parasite. Collars designed for this prevention contain active ingredients like deltamethrin, which acts as a highly effective repellent against these insects.
The mechanism is simple yet powerful: the collar releases the active ingredient continuously, which spreads across the dog’s skin and coat. This creates a protective barrier that repels the sandfly before it can bite, drastically reducing the chances of infection. While no method offers 100% protection, studies show that high-quality collars can reduce the risk by up to 90% when used correctly and continuously during the sandfly season.
Key factors for choosing the best collar against leishmaniasis
Not all flea and tick collars are equally effective against sandflies. Before buying, consider the following:
- Active ingredient: deltamethrin is the most recommended for leishmaniasis prevention.
- Duration of protection: some models last 4 months, others up to 8 months. The longer it lasts, the more convenient and safer it is for your dog.
- Water resistance: important if your dog swims or lives in humid areas.
- Size and fit: it must fit snugly around the neck for even distribution of the active ingredient.
- Certification: ensure it’s an approved product by veterinary health authorities.
Best flea and tick collars against leishmaniasis
Here are some of the most effective and veterinarian-recommended collars for preventing canine leishmaniasis:
1. Scalibor
Contains deltamethrin and provides up to 6 months of protection against sandflies, ticks, and mosquitoes. Water-resistant and widely used in leishmaniasis-endemic areas.
2. Seresto
Combines imidacloprid and flumethrin. While its main action is against fleas and ticks, studies show some repellent effect against sandflies, making it an alternative in moderate-risk areas.
3. Other deltamethrin collars
Some lesser-known brands also offer models with deltamethrin, but always make sure they have proper certification and proven effectiveness.

Tips to maximize protection
A flea and tick collar for leishmaniasis is effective on its own, but its protection is greatly enhanced when used correctly and combined with other preventive measures. Simply putting it on and forgetting about it is not enough—you must ensure it’s properly fitted, in good condition, and complemented by habits that minimize sandfly exposure.
- Put it on 1–2 weeks before sandfly season starts: this allows the active ingredient to fully distribute on the dog’s skin before the first exposure.
- Ensure a proper fit: you should be able to fit two fingers between the collar and the neck for comfort, while still ensuring good contact.
- Keep it on at all times: removing it, even for a few hours, can create a risk window during which your dog is unprotected.
- Avoid frequent baths with shampoo: while water doesn’t deactivate it, repeated shampoo use may shorten its effectiveness.
- Combine with other measures: in high-risk areas, consider vaccination and avoid walks at dawn or dusk in humid zones.
Following these tips will not only improve the collar’s effectiveness but also create a stronger protection barrier, especially if your dog lives or walks in leishmaniasis-endemic areas.
Common mistakes when using a flea and tick collar for leishmaniasis
Even the best flea and tick collar loses much of its effectiveness if certain mistakes are made. Most of these errors are due to lack of knowledge, but they can significantly compromise your dog’s protection.
- Putting it on too late: if you start after sandfly season begins, the active ingredient won’t have time to distribute properly.
- Removing it for baths and forgetting to put it back on: this leaves your dog exposed during high-risk hours or days.
- Using an expired or damaged collar: worn-out products won’t release the proper dose of active ingredient.
- Buying fakes or uncertified products: these may be ineffective or even harmful.
- Incorrect fit: too loose reduces skin contact, too tight may cause chafing and discomfort.
A certified, properly fitted collar used throughout the risk period is one of the best health investments you can make for your dog.
Frequently asked questions about flea and tick collars for leishmaniasis
What is the best collar for leishmaniasis prevention?
The most recommended by veterinarians is the Scalibor collar, which contains deltamethrin and offers up to 6 months of effective protection against sandflies, as well as acting against ticks and mosquitoes.
Does the collar protect 100%?
No collar offers complete protection. However, a quality collar worn continuously throughout the season can reduce infection risk by up to 90%, especially when combined with other preventive measures such as vaccination and limiting exposure during peak hours.
When should I put the collar on?
It’s recommended to put it on at least 2 weeks before sandfly activity begins, so the active ingredient is fully distributed on the dog’s skin by the first day of risk.
Can I use the collar along with the leishmaniasis vaccine?
Yes. In fact, in high-risk areas, it’s advised to combine both methods since the vaccine reduces the severity of the disease and the collar reduces the chance of infection. Using only one method lowers overall protection.
What if my dog gets wet while wearing the collar?
Collars like Scalibor are water-resistant, so occasional bathing or rain won’t affect their effectiveness. However, frequent baths with shampoo or in chlorinated pools can shorten their lifespan.
Can I use the collar on puppies?
Scalibor can be used on puppies from 7 weeks of age. Always consult your vet before use, especially if the puppy is very young or has health issues.
Are natural collars effective against leishmaniasis?
Natural collars with citronella or lavender may repel some insects but have no proven effectiveness against sandflies, so they are not recommended as the sole protection method.
