What is the Scalibor collar and how does it work?
Scalibor is an antiparasitic collar developed by MSD Animal Health that works through the controlled and continuous release of deltamethrin, an active ingredient with insecticidal and repellent effects. This substance spreads over the dog’s skin lipid layer, forming a protective barrier that repels and neutralizes parasites on contact, without needing to bite.
This collar stands out for its effectiveness against ticks, mosquitoes, and sandflies, making it especially useful in preventing leishmaniasis. The effect builds up progressively, so it’s recommended to apply it at least one to two weeks before the start of parasite season. Its action lasts for up to 6 months without the need for monthly reapplications.
Main benefits of the Scalibor collar
- Reduced leishmaniasis risk: thanks to its ability to repel sandflies, the primary vector of this serious disease.
- Repellent and lethal action: not only deters parasites but also kills them on contact without needing a bite.
- Long-lasting protection: continuous defense for up to 6 months with just one application.
- Practical and convenient: applied only once, avoiding the need for frequent pipette or topical treatments.
- Ideal for active or outdoor dogs: its water-resistant design is perfect for dogs that get wet or play outside.
Scalibor is especially recommended in warm or humid regions where parasites are active most of the year.
Is the Scalibor collar safe for all dogs?
Scalibor is safe for most adult dogs and puppies over 7 weeks old. However, caution is advised in households where dogs and cats live together, as deltamethrin can be toxic to cats if they lick the dog’s collar.
If your dog has sensitive skin or has had bad reactions to other antiparasitic collars, it’s best to consult your vet before use. If signs of irritation or allergic reaction appear (redness, excessive scratching, or behavior changes), remove the collar and monitor your dog’s condition.

How to properly fit a Scalibor collar?
To ensure maximum effectiveness of the Scalibor collar, proper fitting from day one is essential. Follow these steps:
- Open the package, remove the collar and unroll it carefully. Avoid bending or forcing it abruptly.
- Place the collar around your dog’s neck, leaving enough space to comfortably insert two fingers between the collar and the skin.
- Trim any excess collar, leaving about 2 to 3 centimeters after the buckle to avoid dangling parts.
- Ensure the dog cannot reach or chew on the collar during play.
- Apply the collar at least 1–2 weeks before high parasite activity seasons begin.
After fitting the collar, wash your hands thoroughly with soap and water. Do not allow other animals, especially cats, to lick or come into direct contact with the collar.
When is it advisable to use Scalibor?
Scalibor is especially suited for dogs living in or walking through areas with sandflies and mosquitoes, such as coastal or Mediterranean regions where canine leishmaniasis is endemic. It’s also highly useful for:
- Times of the year with high parasite activity: spring, summer, and parts of autumn.
- Dogs that go out to the countryside: areas with tall grass, woods, gardens, or wetlands are common parasite zones.
- Dogs living outdoors: those in houses with yards, farms, or frequent outdoor access.
Avoid combining Scalibor with other external antiparasitic products unless prescribed by a vet. A well-planned preventive strategy is the best way to avoid serious diseases like leishmaniasis.
Frequently asked questions about Scalibor collars
How long does it take for the Scalibor collar to start working?
The full effect of the Scalibor collar is noticeable between 1 and 2 weeks after application. That’s why it’s recommended to put it on before sandfly, tick, or mosquito season begins. Deltamethrin needs time to distribute evenly across the dog’s skin.
Does Scalibor protect against leishmaniasis?
Yes. Scalibor is specifically designed to repel sandflies, the main carriers of leishmaniasis. While no method offers 100% protection, the collar significantly lowers the risk of infection, especially when combined with other measures like avoiding walks at dusk.
Can the Scalibor collar get wet?
Yes, the Scalibor collar is water-resistant. Your dog can get wet in the rain or splash around while staying protected. However, frequent bathing or using insecticidal shampoos may reduce its effectiveness. If the collar gets wet, gently dry it with a towel.
Can I use Scalibor on puppies?
Scalibor is suitable for puppies over 7 weeks old. Make sure your puppy is healthy and has the appropriate weight before applying it. If in doubt, consult your vet before first-time use.
Is Scalibor safe for cats?
No. Scalibor is not safe for cats. It contains deltamethrin, which is highly toxic to felines even in small amounts. If dogs and cats live together, ensure the cat cannot access or lick the dog’s collar.
How long does Scalibor protection last?
Scalibor provides up to 6 months of continuous protection against ticks, mosquitoes, and sandflies. After this period, replace the collar to ensure your dog remains protected, especially in high-risk areas.
