Product Description
The Seresto Dog Collar offers up to 8 months of continuous defence against fleas and ticks, using a slow-release technology that ensures consistent protection without the need for monthly treatments. It begins working within 24 hours and continues to kill and repel pests effectively, making it an ideal choice for busy pet owners looking for a low-maintenance solution.
This odourless, water-resistant collar contains two active ingredients - imidacloprid and flumethrin which work together to kill fleas and repel ticks before they bite.
Key Features:
8 months of protection against fleas and ticks
Starts killing fleas within 24 hours
Repels and kills ticks to reduce the risk of disease transmission
Odourless and non-greasy for pet and household comfort
Water-resistant - remains effective even after swimming or bathing
Vet-recommended and clinically proven
Sizes Available:
Small dogs (under 8kg)
Large dogs (over 8kg)
Both sizes offer the same 8-month protection but differ in collar length for correct fit and comfort.
Directions for Use:
Remove the collar from the packaging and unroll it.
Adjust around your dog’s neck for a snug fit—ensure two fingers can fit between the collar and your dog’s neck.
Cut off any excess collar length beyond the loop.
Check regularly to ensure the fit is still appropriate, especially for growing puppies.
When to Use:
Use year-round to prevent fleas, ticks, and associated illnesses such as Lyme disease and flea allergy dermatitis.
Suitable for dogs aged 7 weeks and older.
