Frequently asked questions about the Seresto collar for small dogs
Is the Seresto collar safe for small dogs?
Yes. The Seresto collar for small dogs is formulated for pets weighing up to 8 kg (17 lbs), with an active ingredient dosage adjusted to their weight. The release is slow and controlled, reducing unnecessary exposure. It also features a safety release mechanism that allows the collar to give way if it gets caught, minimizing the risk of strangulation.
Does it protect against leishmaniasis?
No. Seresto is not designed to repel the sandfly (mosquito that transmits leishmaniasis). If you want protection against this disease, consider specific collars such as Scalibor or other options recommended by your veterinarian, and combine them with environmental measures (avoiding walks at dusk, using mosquito nets, etc.).
How long does it take to work?
It acts against fleas in approximately 24 hours and against ticks within 48 hours after application. To maintain constant protection, keep the collar on continuously.
Is it water-resistant?
Yes. It remains effective after rain and occasional baths. There is no need to remove it for quick showers, but frequent use of antiparasitic shampoos or regular swimming may shorten its effective lifespan.
How long does its protection last?
It provides up to 8 months of protection against fleas and ticks under normal conditions. In very hot climates, heavy infestations, or with frequent water exposure, some veterinarians recommend replacing it after 6–7 months.
From what age and weight can it be used?
The minimum recommended age is 7 weeks. The small dog version is intended for pets weighing up to 8 kg (17 lbs). If your dog exceeds this weight, choose the large dog version to ensure the correct dosage.
How do I know if I should buy the small dog or large dog Seresto?
Use weight as your guide: up to 8 kg → small dogs; over 8 kg → large dogs. It is not about the collar's length, but about the dosage of active ingredients adapted to the dog's weight.
How do I correctly fit it on a small dog?
Follow these steps:
- Adjust leaving space for two fingers between the neck and collar.
- Trim the excess strap to prevent chewing.
- Do not use it as a walking collar; attach the leash to a separate collar/harness.
- Check the fit every 2–3 weeks, especially if your dog is growing or losing weight.
Can it cause allergies or skin irritation?
It is rare, but some sensitive dogs may show mild itching, redness, or hair loss in the contact area during the first 24–48 hours. If irritation persists or worsens, remove the collar and consult your vet. Avoid use if there are open wounds or active dermatitis on the neck.
Can it be used on pregnant or lactating females?
The manufacturer states it is suitable for pregnant and lactating females; however, it is advisable to consult your veterinarian before use, especially if the dog has a history of skin sensitivity.
Can I combine Seresto with spot-on treatments or oral antiparasitics?
In some high-risk situations (rural areas, warm climates, multi-pet households), your vet may recommend combining treatments. Do not mix products on your own: always consult your vet to avoid overexposure to the same active ingredients.
What if my small dog tries to chew or remove the collar?
Try the following:
- Ensure a proper fit (two fingers) and trim the excess.
- Distract with toys or treats during the first minutes.
- Consider a temporary Elizabethan collar if chewing persists.
If damaged, replace it: a broken collar may lose its effectiveness.
Can I bathe my dog or take it to the groomer with the collar on?
Yes, but avoid frequent antiparasitic shampoos as they can reduce its lifespan. After a bath with shampoo, dry the coat thoroughly and check that the collar is still properly fitted.
What if I find a tick on my dog despite using Seresto?
A tick may still attach before being affected by the product. Remove it carefully using a tick removal tool (without crushing) and disinfect the area. Check the collar's fit and ensure it is not expired or damaged.
Is it compatible with a harness or another ID collar?
Yes. Seresto can be used along with a harness or an identification/walking collar. Remember: do not attach the leash to the Seresto collar to avoid tension damage.
Is it safe around children or cats?
Supervise interactions to prevent children from handling the collar and wash your hands after touching it. Around cats, it is safe, but avoid letting them chew or lick the collar. For very close contact, consider fitting it when the dog is under supervision during the first days.
How can I tell if a Seresto collar is genuine?
Buy from trusted retailers (pharmacies, vet clinics, or reputable stores). Check the batch number and expiry date, the packaging quality, and the leaflet. Be cautious of very low prices and packaging without seals or clear information.
Does it have an expiry date? How should I store it?
Yes. Check the expiry date on the packaging. Store the collar in its original closed tin, in a cool, dry place, away from direct sunlight and out of reach of children and pets.
What if the collar leaves a white powder or has a strong smell when opened?
A slight powder residue at first is normal. Shake it gently before placing it on your dog and wash your hands after handling. The collar is odorless during use; if you detect a strong chemical smell or notice skin irritation, remove it and consult your vet.
Does it interfere with the microchip or a GPS tracker?
No. Seresto does not affect the microchip or interfere with GPS/Bluetooth devices. Just make sure they do not overlap in a way that could rub or cause discomfort.
My dog has long hair but weighs less than 8 kg. Should I get the small dog version?
Yes, the choice depends on weight, not coat type. For long-haired dogs, ensure good skin contact (two-finger fit) and check every 2–3 weeks to avoid it becoming too loose.
Can it cause drowsiness, vomiting, or lethargy?
This is uncommon. If you notice symptoms such as lethargy, vomiting, or excessive drooling, remove the collar and contact your vet. Consider previous reactions to antiparasitics and mention any other medications your dog is taking.
How can I remember when to replace it?
Write down the application date on the tin or in your phone and set a reminder to replace it after 8 months (or sooner if your dog swims often or you live in a high-risk area).
