Seresto collars are a popular choice among pet owners for flea and tick control, offering convenience and long-lasting protection for dogs. However, concerns have been raised about the potential impact of Seresto collars on seizures in epileptic dogs. In this informative blog post, we'll delve into what Seresto collars are, the materials used to make them, and why they may affect seizures in dogs with epilepsy.
What is a Seresto Collar?
A Seresto collar is a type of flea and tick collar designed to provide continuous protection against these parasites for up to eight months. Unlike traditional flea collars, Seresto collars use technology to release active ingredients gradually over time, repelling and killing fleas, ticks, and other pests without the need for monthly applications.
Materials Used in Seresto Collars
Seresto collars contain two main active ingredients: imidacloprid and flumethrin. Imidacloprid is a neonicotinoid insecticide that disrupts the nervous system of fleas and ticks, leading to paralysis and death. Flumethrin is a synthetic pyrethroid that repels and kills ticks upon contact. These ingredients are embedded in a polymer matrix within the collar, allowing for controlled release over an extended period.

Potential Impact on Seizures in Dogs with Epilepsy
While Seresto collars are generally considered safe for most dogs, some pet owners have reported an association between the use of these collars and an increase in seizures in epileptic dogs. The exact mechanism behind this potential link is not fully understood, but it is believed to be related to the active ingredients, particularly imidacloprid.
Imidacloprid works by targeting the nervous system of insects, and while it is generally well-tolerated by dogs, there is a possibility that it may affect the neurological function of epileptic dogs, potentially triggering seizures. Additionally, some dogs may have a hypersensitivity or intolerance to the ingredients in Seresto collars, leading to adverse reactions including seizures.

How Imidacloprid Harms the Nervous System of Dogs
Imidacloprid acts as a neurotoxin, targeting the nervous system of insects by binding to specific receptors called nicotinic acetylcholine receptors. These receptors are essential for normal nerve signal transmission in insects. When imidacloprid binds to these receptors, it disrupts the normal function of the nervous system, leading to paralysis and ultimately death in fleas and ticks.
While imidacloprid is generally considered safe it is important to note that it can also affect mammals, including dogs, although to a lesser extent. In dogs, imidacloprid may interfere with normal neurological function if ingested or absorbed in large quantities, potentially leading to adverse effects such as tremors, weakness, and seizures.
Imidacloprid Toxicity in Dogs
Imidacloprid toxicity in dogs is relatively rare and usually occurs when dogs ingest large amounts of the chemical or are exposed to concentrated formulations. Symptoms of imidacloprid toxicity may include drooling, vomiting, diarrhea, tremors, weakness, and seizures. In severe cases, imidacloprid poisoning can lead to respiratory distress, coma, and death. If you suspect that your dog has been exposed to imidacloprid or is experiencing symptoms of toxicity, seek veterinary care immediately for prompt treatment.

Conclusion: Seresto Collars and Seizures
While Seresto collars are an effective option for flea and tick control in many dogs, pet owners should be aware of the potential risks associated with their use, particularly in epileptic dogs. It's essential to weigh the benefits of flea and tick prevention against the potential risks of increased seizure activity and to consult with a veterinarian if you have concerns about your dog's health or the use of Seresto collars.
