How Does Seresto Dog Collar Work?

While reading Seresto Flea collar reviews, we noticed that people want to know how this collar actually works. So, here’s explanation. Seresto collar contains two active ingredients. These two ingredients work together to deliver a powerful reaction, freeing your furry pet from parasites. Here’s why these two makes a great team.

  • Imidacloprid: This insecticide eliminates adult fleas and larvae fleas.
  • Flumethrin: This ingredient repels adult ticks and larvae, preventing transmitting illnesses to your dog and you.

Seresto Dog Collar is made of an innovative material known as the polymer matrix. Imidacloprid and Flumethrin are stored in this material. When the collar comes in a direct touch with the dog’s skin, these ingredients are released. Since these ingredients are active, they will naturally spread over the dog’s body, covering every inch of it.

That way, Seresto kills and repels fleas and ticks, saving your pet from painful bites and different diseases. According to Seresto reviews, customers are pleased with its efficiency. This dog collar works quickly. Namely, it takes 24 hours for ingredients to spread and kill fleas.

Moreover, reinfesting fleas will be killed within 2 hours, and reinfesting ticks will be killed in 6 hours. On top of all, tick infestations will be prevented within 2 days after application. As you can see, the seresto dog collar is very efficient. This is one of the reasons why it is so popular.

How Parasites Affect Your Pet's Life?

As you probably already know, parasites live on/in another creature. Yup, they aren't very noble. Fleas and ticks are most common parasites found in cats and dogs. They usually bother dogs and cats in spring and summer, but they can also persevere in autumn and winter.

Even though these parasites may seem innocent and just an annoyance; things can get much more serious than that. Fleas and ticks can also bring other parasites with them.

Similarly, dog collar can cause allergies. In the worst case, they can carry illness and transfer it to you and your kids.

How to recognize fleas?

Clearly, the first thing in treating your dog is recognizing what’s wrong with her. The first sign of fleas attacking your furry friend is your dog scratching and chewing repeatedly. The next one is your dog being nervous (and how she wouldn't when these ruthless parasites bother her all day?).

Then, you’ll notice irritated skin and hair loss, due to constant scratching. Of course, at some point, you’ll see fleas on your pet or in your home.

What about ticks?

When it comes to ticks, these parasites are also a pain in the ass. But, they don’t live inside of an animal, which is a good thing. We want to point out that both indoor and outdoor dogs can have ticks. So, don’t think that keeping your dog in your home will prevent her from getting ticks.

Ticks feed on your pet’s blood, irritating the skin around that area. Ticks can be pretty bad for your dog’s health, causing different illnesses and even anemia. Some of the diseases these parasites cause are:

  • Lyme Disease: Lyme disease can lead to swelling of your pet’s joints and even arthritis.
  • Rocky Mountain Spotted Fever: This type of disease causes fever, lameness, and many other conditions.

You can see a veterinarian to give you some tips and tricks on how to avoid locations where ticks can be found, as well as how to prevent your pet from getting fleas.

However, you should know that it’s okay to use a flea dog collar. In the end, that’s one of the ways to keep your pet safe from parasites.

Why Choose the Seresto Dog Collar?

After doing research and going through Seresto Collar reviews, we were happy with what we found. That being said, let’s see why the dog and cat collar is considered one of the best, if not the best.

Easy to use

According to Seresto dog collar reviews, customers love the ease-of-use of this flea dog collar. Let’s see how this dog collar differs than its competitors. For example, Topical flea control products are used once a month. Now, the problem is that most pet owners are so busy that they forget to apply this product to their pet. Needless to say, fleas and ticks return, driving your pet crazy.

In addition, applying this product to your pet means coming in touch with chemicals. Imagine what would happen when just a small part of this product would end up on your food, or clothes because you didn't wash it well. Also, there is this awful odor that makes you throw up.

Well, that’s where this flea dog collar comes in handy. It’s safe, easy and simple to use. You just need to adjust it around your dog’s neck, and voila – everything is set and you can relax.

Also, you don’t have to check this dog collar every month; its protection will be at a high level up to 8 months. You simply need to replace it when you notice it doesn't do the job anymore.

Please note that if your dog likes to swim regularly, this dog collar will last less; up to 5-6 months. To buy Seresto dog collar, you won’t need a prescription, which only adds up to its simplicity.


As mentioned above, the Seresto dog collar is highly effective. It will protect your dog from fleas and ticks, flea larvae, chewing lice as well as Sarcoptic mange. What’s more, this dog collar can be used with other products and leash collars. Its performance won’t decrease.


What customers appreciate about Seresto dog collar is that it doesn't release any odor. This means that your kid can play with your dog, without breathing in toxins and odor.


Speaking of toxins, this flea dog collar is perfectly safe for your pet, you and your family; hence you can have a peace of mind. Furthermore, Seresto Collar is recommended by veterinarians.

Water resistant

Another benefit of this dog collar is water resistance. No matter if your dog is standing in the rain, swimming or bathing, Seresto dog collar remains efficient.


Made of high-quality materials, this dog collar is comfortable. Your dog will enjoy wearing it, even after months of use. Also, the collar is adjustable, for maximum protection and comfort.

Speaking of which, make sure to leave enough room so that your dog can breathe normally. If you can easily slip two fingers under the collar, it means the collar is perfectly adjusted. The icing on the cake is added visibility of this collar obtained by light reflectors.


Seresto Flea and Tick Collar for Dogs is also versatile, making it one of the bests on the market. It is suitable for both indoor and outdoor dogs as well as for small and large dogs. But, one of the biggest advantages of this collar is that it will be efficient even if your dog has thick fur. Just make sure to buy the right size and place the collar as close to the skin as you can.


As for the design of this flea dog collar, it’s well-made. It won’t wear and tear after months of use. Also, the Seresto Dog Collar is durable. If you’re worried about whether your dog can take it off, don’t be. The opening system is impossible to break, thus your dog won’t be in danger. However, it is possible for a collar to loosen after a while, especially if your dog is really active. In that case, just re-adjust the collar.

Offers extensive protection

Since this dog collar is effective for up to 8 months, you’ll save a lot of money. You won’t have to spend money on monthly flea treatments.

Keep in mind when using the Seresto Flea Collar

Seresto Flea Dog Collar is durable and efficient. However, don’t think that this collar is indestructible. You have to take care of it if you want your dog to wear it for 8 months.

Don’t bathe your dog too often

So, to make the most out of this flea dog collar, don’t bath your dog couple times a month. Instead, bath her just once a month. If your pet is an avid swimmer, forget about eight-month duration. If your dog swims more than once a month, flea control will last for 5 months, while tick control will last for 7 months.

Keep the collar at your disposal

Since fleas and ticks are very active in the warm weather, you should be mindful when applying the Seresto Flea Collar on your dog. Instead of doing that in spring, do it earlier. Put the collar on your dog’s neck as soon as the temperature rises above zero.

Cannot be used on young puppies

The Seresto Flea Collar cannot be used on young puppies otherwise they would get sick. Besides, if you have young puppies, you shouldn't use any flea and tick treatment, unless it is explicitly made for them (that would be written on the label). That way, your pet will be prepared for their invasion in hot weather.

Some dogs can experience mild allergies and reactions, such as redness, itching, and hairless. However, this usually lasts for a week; until a dog get used to the collar.

But, if the symptoms continue to happen, stop using the Seresto and bath your dog. Also, you should take her to the veterinarian.

In rare cases, the following symptoms can occur:

  • Inflammation
