- Immediate action: kills fleas within the first 24 hours after application.
- Long-lasting prevention: protects for up to 8 months without the need for additional treatments.
- Water-resistant: remains effective even after bathing or exposure to rain.
This controlled-release system minimizes direct contact with the product and reduces the risk of adverse reactions, ensuring constant protection without loss of effectiveness.

- Odorless: ideal for dogs and owners sensitive to chemical smells.
- Water-resistant: does not lose effectiveness in rain or occasional baths.

Key factors before buying a Seresto collar for large dogs
Before purchasing a Seresto collar for large dogs, it is important to evaluate a series of factors that will help you determine if it is the most suitable parasite control solution for your pet. These aspects directly influence its effectiveness, safety, and comfort, and will help you avoid impulse purchases that may not meet your expectations.
- Minimum weight: designed for dogs weighing over 8 kg (17 lbs). Not recommended for smaller dogs due to dosage levels.
- Recommended age: not suitable for puppies under 7 weeks, as their immune system and skin are still developing.
- Health compatibility: if your dog has skin allergies, dermatitis, or open wounds on the neck, always consult a vet before use.
- Activity level: ideal for dogs that spend time outdoors such as in gardens, on long walks, or hiking.
- Geographic area and parasite risk: highly recommended in regions with a high presence of fleas, ticks, or rural environments with dense vegetation. In areas with year-round parasite activity, its 8-month duration is a major advantage.
- Water exposure: although water-resistant, frequent swimming or use of antiparasitic shampoos may slightly reduce its effective duration.
- Comfort and adaptation: the collar is lightweight and flexible, but it is advisable to check during the first few days that your dog adapts well and does not try to remove it.
- Compatibility with other treatments: if your dog is already on spot-on, oral, or injectable parasite control, confirm with your vet whether to continue or suspend them to avoid overexposure.
If your dog meets these requirements, the Seresto collar for large dogs is a safe and effective investment to keep them protected for months. Taking the time to consider these factors before buying ensures you get the maximum benefit and that your dog remains comfortable and safe.
Tips for using the Seresto collar on large dogs
Proper use of the Seresto collar for large dogs is the key to achieving maximum parasite protection. Follow these practical tips to boost its effectiveness, prevent issues, and ensure your dog's comfort throughout the protection period.
- Correct fit: leave space to insert two fingers between the neck and the band. A loose fit reduces product distribution; too tight may cause irritation.
- Adjustment period: observe your dog for the first 24–48 hours. Mild initial itching can be normal; if redness persists, remove the collar and consult your vet.
- Trim excess length: cut off the extra end beyond the buckle to prevent chewing. Do not puncture or modify the collar beyond this.
- Not a walking collar: do not attach the leash to the Seresto. Use a separate walking collar or harness to avoid strain and damage.
- Strategic timing: put it on before flea and tick season or at the start of spring to ensure full protection during peak risk.
- Baths and water: it is water-resistant, so no need to remove it for rain or occasional baths. Avoid frequent antiparasitic shampoos, as they may shorten its duration.
- Regular checks: check the fit every 2–3 weeks (more often if your dog is growing or losing weight). Gently clean the neck area if dirt or mud builds up.
- Skin monitoring: check for chafing, scabs, or hair loss. Remove and consult a vet if any reaction occurs.
- Clean environments: wash bedding, blankets, and vacuum carpets to break the flea life cycle and reinforce the collar's action.
- Compatibility: if using other parasite preventatives, coordinate with your vet to avoid overexposure.
- Swimming dogs: for dogs that swim frequently in rivers or the sea, consider replacing the collar after 6–7 months to maintain peak effectiveness.
- Pregnant or lactating females: always consult your vet before use in these stages.
- Replacement schedule: note the application date and set a reminder for replacement. Never reuse an old or damaged collar.
- Hand hygiene: wash your hands after handling the collar and avoid contact with eyes and mouth. Keep out of reach of children.
- Post-walk inspection: in rural or bushy areas, run your hand through your dog's coat to detect ticks early, even if wearing the collar.
- Comprehensive health plan: combine external parasite control with regular deworming and vet check-ups, especially in high-risk areas.
By following these tips, the Seresto collar for large dogs offers constant, comfortable, and long-lasting protection. Use it as part of a complete preventive care plan to ensure your dog stays protected all year round.
Frequently asked questions about the Seresto collar for large dogs
Is the Seresto collar safe for large dogs?
Yes. The Seresto collar for large dogs is formulated specifically for dogs over 8 kg (17 lbs), with an active ingredient dosage adapted to their size. It uses imidacloprid and flumethrin in a controlled release that minimizes exposure and reduces the risk of adverse reactions. When used according to the manufacturer's instructions and ensuring the dog is not allergic to its components, it is safe. It also includes a safety-release mechanism to prevent accidental choking if snagged.
Does it protect against leishmaniasis?
No. The Seresto collar is not designed to repel sandflies (phlebotomines) that transmit leishmaniasis. It targets fleas, ticks, and lice. For leishmaniasis protection, consider alternatives like Scalibor or Preventic, which have proven effectiveness against sandflies. In high-risk areas, combine parasite protection with additional vet-recommended measures.
How long does it take to work?
The collar begins killing fleas within the first 24 hours and ticks within 48 hours after application. For complete protection, apply it before the start of peak parasite season. Its effect is continuous thanks to the constant release of active ingredients.
Is it water-resistant?
Yes. The Seresto collar is water-resistant and remains effective after occasional baths, rain, or play in wet areas. However, very frequent swimming or use of antiparasitic shampoos may slightly reduce its duration, so in such cases, monitor the replacement schedule.
How long does its protection last?
It offers continuous protection for up to 8 months against fleas and ticks, as long as it is worn without interruption. In very hot climates, with heavy infestations, or with frequent water exposure, some vets recommend replacing it after 6–7 months to ensure peak performance.
Can it be combined with other parasite treatments?
In most cases, yes, but always under veterinary guidance. In high-risk environments with internal and external parasites, combining the collar with other methods may be beneficial. However, to prevent overexposure to active ingredients, dosage and timing must be carefully managed.
Does it require maintenance or checks during use?
Yes. While the collar works continuously, it is advisable to check every few weeks to ensure it still fits correctly, especially in young or growing dogs. Clean the neck area periodically and check that no dirt build-up is affecting the release of active ingredients.
