Can dogs get sick from Seresto

Seresto collars for dogs are not only safe for the pet, but research shows that the product is actually very effective in controlling fleas and ticks. The active ingredients in the collar have an 8-month protection duration, yet remain safe for both humans and pets.

However, some animals may be allergic to certain chemicals used in Seresto collars. These include Benzyle alcohol, Ethyl acetate or Dioctyl Sodium Sulfosuccinate. If you have any concerns about your pet’s reaction to these ingredients, please consult with your veterinarian prior to use of a Seresto collar.

In addition, it is generally advised not to use more than one type of pesticide (e.g., topical treatments) on a dog at once. This may increase the risk of adverse effects, as multiple chemicals together can create a toxic environment for your pet. Therefore, if using a Seresto collar you should discontinue using other flea and tick products on your animal at the same time.

All in all, when used properly and following instructions included in the product insert, there appears to be minimal risk of pets becoming sick from using Seresto collars; however it would be better to consult with a veterinarian before usage just to ensure complete safety of the pet involved.

What Is Seresto?

Seresto is a popular flea and tick collar for dogs. It utilizes a slow-release technology that offers 8 months of continuous protection against fleas and ticks. It’s made with two active ingredients: imidacloprid and flumethrin. These two active ingredients work together to kill and repel adult fleas and ticks, while also preventing the further development of eggs, larvae, and pupae from hatching.

It’s noted for being odorless, non-greasy, and water-resistant. This makes it a great option for pet owners who want to keep their pet safe from pests but don’t want to interfere with their grooming routine or cause any irritation or allergic reactions. Because Seresto works gradually over time, it’s easy to forget how much protection your pet has if they’re wearing it! So be sure to check in on your pup regularly and replace the collar when needed.

How Does It Work?

Seresto is a flea and tick collar designed specifically for dogs. It has an flea & tick collars active ingredient called Imidacloprid, which kills and repels fleas and ticks on contact. There is also an additional protective layer of flumethrin that prevents future infestations.

So how does the Seresto collar work? After you apply the collar to your dog, it slowly releases small amounts of Imidacloprid and Flumethrin into the fur –– this creates a barrier around your dog which deters fleas and ticks from coming into contact with their skin. It can last up to 8 months on one set of chemicals so you don’t have to worry about replacing it often! Thankfully, no –– dogs cannot get sick from Seresto as long as it is used correctly according to instructions given by its manufacturer.

Is It Safe for Dogs?

When it comes to determining whether Seresto collars are safe for dogs, the answer is yes! While there have been some reports of skin irritation in some dogs, these incidents are rare and usually resolve themselves in a short period of time.

The collar contains active ingredients derived from natural products that are safe for pets; however, you should always consult your veterinarian before using this product on your pet. The collar also includes safety features such as an “anti-overdose” system that releases a measured dose over time. This means that even if your pup chews or bites their collar, it won’t lead to an overdose. Additionally, the chemical components found in the collar break down slowly over 8 months so your pet is constantly protected!

Overall, Seresto is considered a very safe product for both cats and dogs. However, as with any new product you introduce to your pet’s environment, be sure to discuss it with your vet prior to using it.

How Long Does it Last?

When it comes to Seresto flea and tick protection, how long it will last depends on the size of your dog. Seresto is an effective flea and tick prevention product that lasts 8 months on small dogs (under 18 pounds) and up to 5 months on large dogs (over 18 pounds).

The active ingredients in Seresto, imidacloprid and flumethrin, work together by killing fleas quickly, which then prevents them from laying eggs and infesting your home. Additionally, the long-acting protection helps prevent future infestations for the length of time specified above.

Since Seresto is designed to keep your pet free from both fleas and ticks for a significant time period, you also don’t have to worry about serious illnesses or other hazards caused by these annoying pests. However, for extra precaution, make sure you check your dog regularly for any signs of fleas or ticks during their full course of treatment.


While Seresto is a great way to help protect your pet from fleas and ticks, it’s important to remember that there are other products on the market which are just as effective. It’s important to research the pros and cons of each product before choosing one that suits your needs best.
