Seresto Flea and tick Collar for Dogs Review

When the weather is warm out, fleas and ticks thrive, which is bad news for your dog. Your pup probably loves playing in the yard and hanging out at the park, but these events can become scary due to pests. There are lots of different flea and tick preventatives that can protect your dog from these critters. So, we have written this Seresto collar review to determine whether or not Seresto is a good preventive for your dog.

Seresto dog Collar Review Summary

The Seresto Flea and Tick Collar is a flea and tick preventative that goes around your dog’s neck like a normal collar. It can provide up to 8 months of protection from pests, and it kills fleas and ticks upon contact, including flea eggs and larvae. It also kills lice and controls mange. The bugs don’t have to bite your dog to be affected by this collar. Also, not only does it kill pests, but it also repels them, which is something that not all preventatives do.

This is a veterinarian-recommended collar that’s gray with no odor or grease on it. Once you put it on your dog, it starts repelling fleas within 24 hours and ticks within 48 hours. The collar is long and adjustable, so you can set it to the correct size for your dog and then remove the extra part of the collar. It also comes in different sizes for dogs under 18 pounds, dogs over 18 pounds, and even cats. Plus, it’s easily removable if needed. It’s also waterproof, so if your dog swims once in a while or takes occasional baths, then the collar won’t be affected.

Pros:

  • It kills fleas and ticks upon contact.
  • It also kills lice and controls mange.
  • The collar is adjustable.
  • It has no odor and no grease.
  • It works for up to 8 months.
  • It’s veterinarian-recommended.
  • It’s not affected by water.

Cons:

  • It’s a bit pricey.
  • It could cause reactions for some dogs.
  • It’s possible to receive an expired product.

Features and Benefits / Does Seresto work ?

Unlike most flea and tick preventatives, Seresto not only kills fleas and ticks after they bite, but it also repels them from climbing on your dog. We’re going to take a more in-depth look at these features and benefits.

Seresto Kills Fleas and Ticks

How does Seresto work? Seresto uses two active ingredients in the collar: imidacloprid and flumethrin. When you put the collar on your dog, those ingredients are steadily released throughout your dog’s skin and coat. The ingredients use your dog’s skin and coat to spread from your pup’s nose all the way to their tail. This is what allows it to repel fleas and ticks so effectively.

These ingredients are released specifically into your dog’s lipid layer, which is the fatty or oily part of their skin. These ingredients stay in your dog’s skin when the collar is worn, killing fleas and ticks even in large quantities, including flea eggs and larvae. This process can last for up to 8 months.

The collar might look like it’s made out of a simple plastic material, but it’s actually made with a fine polymer matrix. This substance helps control the amount of imidacloprid and flumethrin that’s spread throughout your dog’s skin. It ensures that your dog gets enough to be protected, but not so much that it could be harmful for them. The collar type along with the active ingredients are what makes Seresto one of a kind.

It takes 24 hours for these items to spread throughout your dog’s entire body, but when they do, they become the ultimate pest killer. Continuously wearing the collar for 8 months is all you have to do to keep these active ingredients on your dog. Plus, your dog will have no grease or odor from the collar.

After 24 hours, fleas and ticks will die when coming into contact with your dog’s coat. Some preventatives require bugs to bite your dog for the preventative to work, but that’s not as safe for your dog. With Seresto, bugs never even have to hurt your pup to be affected. Therefore, Seresto’s unique ingredients can kill fleas, ticks, and even mites just by touching your dog.

Seresto Repels Fleas and Ticks

Topical and consumable flea and tick preventatives often brag about how they kill these pests. However, they don’t actually repel them the way that Seresto does. Killing fleas and ticks that bite is effective, but it’s even more effective if the bugs avoid your dog altogether. Therefore, Seresto uses imidacloprid and flumethrin to also repel these critters rather than just killing them upon contact.

Repelling fleas and ticks is more effective because it never gives new bugs a chance to bite your dog. Fleas can cause painful sores from biting and ticks can transmit Lyme disease or Rocky Mountain spotted fever. If they don’t bite your dog at all, then your dog will never come into contact with these dangerous health concerns.

It’s Easy to Use

Unlike traditional flea and tick products, Seresto collars are easy to use. They require no mess and no monthly commitments. You just put them on your dog like you would with a normal collar and it starts working within a day. Other preventatives might require you to feed your dog something or place something on your dog’s back, but this product takes minimal effort.

The collar comes in a long size in order to fit every dog. There are sizes for large and small dogs, but it’s likely that the collar won’t fit exactly right out of the box. When you put it on your dog, you can adjust it as needed and then cut off the excess collar pieces. When putting it on, you just need to remember that it shouldn’t be too tight around your dog’s neck. Usually, you should be able to easily fit two of your fingers between your dog’s neck and the collar. Luckily, it’s easy to remove if you put it on too tight or if you need to take it off. 

It Lasts for 8 Months

One of the most unique features of Seresto is that it lasts for up to 8 months. Most topical preventatives need to be applied every month while chewable preventatives are usually given every three months. Therefore, Seresto is more convenient and more affordable.

Lasting 8 months isn’t the only thing that makes it stand out though. Other treatments can be messy or difficult to give to your dog. With Seresto, all you have to do is put the collar on them and it will start killing and repelling bugs. You can leave it on your dog both inside and outside. Additionally, you can even keep it on your dog if they take a bath or go swimming. However, too much water could affect the collar, so check the label to make sure your dog isn’t bathed with it too often. All these unique features are what help it last so long.

If you ever need to remove your Seresto collar, it’s easy to take it off. It has two safety mechanisms: a ratchet-release mechanism and a predetermined breaking point where it can be ripped apart. This is in place in case an emergency occurs where your dog could be at risk of choking. 

Things to Consider Before Buying a Seresto Collar for dogs

Every dog needs flea and tick treatments during warm months. However, topical flea treatments can be messy and chewable ones can be pricey. So, these medications can often seem like more trouble than they’re worth. Luckily, flea collars are a great alternative to other flea treatments. 

Seresto collars are ideal for dog parents that want their dogs to play outside often, but don’t want to waste time and money on other flea treatments. Also, it can be a great product to try if other flea and tick treatments haven’t been working properly for your dog. After all, fleas and ticks often gravitate toward your dog’s neck and face area, which is where the collar will be. However, the collar is still effective for the entire body, and it should kill pests upon contact, not just after they bite.

Before you decide to purchase a Seresto collar, you should make sure your dog is free of fleas and ticks. Flea and tick preventatives are designed to kill and repel pests, but they should not be used just to treat ones that are already infesting your dog’s coat. If your dog already has bugs crawling in their coat, you’ll want to have the vet treat them before starting another preventative. That way, your vet can give you the best recommendation for what steps to take next.

Seresto collars are also only suitable for dogs 7 weeks of age or older. So, if you have a young puppy, you’ll have to wait to start using this flea and tick preventative. Another common mistake dog parents make is using Seresto with another flea preventative at the same time. It seems like this would make your dog extra protected, but that’s only a myth. It’s a bad idea because then you’re doubling the dosages for your dog, which could be harmful for their health. So, you should only use Seresto if your dog is not currently on another preventative.

Alternatives

Seresto isn’t the only flea and tick collar out there. There are lots of other companies that are also trying to find ways to keep your dog safe from pests. So, I’ve taken a look at three alternatives to Seresto and analyzed them based on features, pros, and cons.

SOBAKEN Flea and Tick Prevention

This flea and tick collar also lasts for 8 months, but it’s more affordable than Seresto. It can protect your dog from fleas, lice, mange, flea larvae, and lice. The formula is completely natural and hypoallergenic. It’s waterproof and easy to get on, just like Seresto. It can be used for dogs of any size, and it can be used on any dogs older than 3 months. It works similarly to Seresto, where it slowly releases the ingredients to be distributed throughout your dog’s skin. Additionally, a portion of the proceeds from this collar are donated to charity.

This product is fairly similar to Seresto since it works the same and lasts for the same amount of time. Plus, they’re both waterproof and easy to put on. Unlike other flea and tick collars, both of them also protect your dog from lice and mange too. The main difference is that this product is cheaper than Seresto, however, it has been reported to not be as effective.

Pros:

  • It lasts for 8 months.
  • It’s waterproof.
  • It’s more affordable than Seresto.
  • It’s easy to put on.
  • It protects against fleas, ticks, flea larvae, lice, and mange.
  • A portion of the proceeds are donated to charity.

Cons:

  • It’s not as effective as Seresto.
  • It has an odor.
  • The item could arrive missing.

Hartz UltraGuard Collar

This collar is by far the most affordable option, but it only prevents fleas and ticks for 7 months as opposed to 8 months. It kills and repels fleas, ticks, flea eggs, and flea larvae. Like Seresto, it kills upon contact, so the fleas and ticks don’t have to bite your dog for it to work. The collar is water-resistant, so it won’t be any less effective if it gets wet. It’s suitable for any dogs that are 12 weeks or older, and can fit any dog’s neck that is up to 22 inches around. 

This collar has the same purpose as Seresto, but it’s not as safe and affordable. Both products repel fleas and ticks upon contact and they’re both waterproof, but this product doesn’t protect dogs from mange or lice. The most significant difference between the two is the price. This product is cheaper than any other preventative, but there seems to be a reason for that. Unlike Seresto, this product causes reactions for lots of dogs, causing rashes and hair loss.

Pros:

  • It’s extremely affordable.
  • It lasts for 7 months.
  • It kills fleas and ticks upon contact.
  • It also kills flea eggs and larvae.
  • It’s waterproof.

Cons:

  • It doesn’t protect against mange, lice, or mosquitoes.
  • The ingredients are not hypoallergenic.
  • It could give your dog a reaction.

Arava Flea and Tick Prevention Collar


This is another flea and tick collar that’s more affordable than Seresto, but it only lasts around 6 months. Not only does it kill fleas and ticks, but it’s capable of repelling about 500 different insect species. It’s completely natural and made with herbal ingredients and essential oils. Unlike the gray color of most flea and tick collars, this option is light green. Like Seresto, it uses a similar slow release process to distribute the active ingredients across your dog’s entire body. It has a soothing natural scent that will slowly become less strong after one or two days. Additionally, the collar is waterproof. This company donates a portion of their proceeds to animal rights charities.

Seresto is fairly similar to this product, but it’s still a bit more expensive. Both of these products use a slow release process to protect your dog, and both collars are waterproof. There is a clear difference in appearance since Seresto is a simple gray design while this one is a rounded green design. Also, this product has a scent to it while Seresto has no odor and no grease. However, this product claims to repel against 500 different insect species, which is something Seresto doesn’t do.

Pros:

  • It’s more affordable than Seresto.
  • It’s made with natural ingredients.
  • It can repel about 500 different insect species.
  • It’s waterproof.
  • The company donates a portion of proceeds to animal rights charities. 

Cons:

  • It doesn’t last as long as other options.
  • It has a scent.
  • It’s not always effective.

Conclusion Seresto collar review

Seresto is one of the most effective flea and tick collars out there because it not only kills fleas and ticks, but it also repels them for up to 8 months. Plus, it’s easy to use and it has no odor or grease. So, if you’re looking for an easier way to prevent fleas and ticks from getting on your dog, Seresto might be the right choice for you.
