As compared to other products on the market, Seresto dog collars are the only ones that kill and repel fleas and ticks at the same time. In this article, we’ll review the Seresto flea and tick collar, see how it works, discuss whether or not it is safe, and evaluate its pros and cons.

How Does Seresto Dog Collar Work?

bayer seresto flea and tick collar for dogs reviews

The Seresto collar is the most innovative and unique collar for protection against fleas, ticks, lead larvae, and lice. Let’s understand how the Seresto collar works.

Seresto collars consist of a polymer matrix that steadily releases two active ingredients that spread all over your dog’s skin and hair, from head to toe. These two ingredients are imidacloprid and flumethrin.

Imidacloprid is an insecticide that acts on the central nervous systems of insects. It is known to be harmful to sucking insects and some soil insects, termites, and fleas on pets.

Flumethrin is another insecticide that is commonly used in veterinary medicine for parasitic insects, mites, and ticks.

As the Seresto dog collar releases two ingredients, they form an invisible layer of protection on the dog and kill fleas and ticks that come in contact with the dog.

Special Features of Seresto Dog Collar

The Seresto dog collar is the most highly recommended flea collar when it comes to protection against fleas, ticks, lead larvae, and lice.

If you are looking for a flea and tick product that does not need to be applied monthly, then this is the perfect solution for you. It is also ideal for people who have sensitive dogs and may have a severe reaction to oral flea and tick products.

For livestock guard dogs and dogs who live close to the woods or farm, Seresto flea and tick collar have proven to be very effective.  

I have a German shepherd, and I am hesitant to use any of the topical flea treatments on him because I have young kids, and I am afraid that they will touch them.

When I tried Seresto dog collar, it worked really well for me, and my dog has not developed any adverse reactions to it.

What differentiates the Seresto collar from other similar products is that it’s still considered a topical product, but it is not greasy, so it doesn’t leave any residue.

The best part about Seresto collars is that you can leave them on your dog while swimming or during regular baths.

What has made the product very popular among users is that it lasts for eight months. If you have a dog that swims a lot, the life expectancy of the product may reduce to around five months.

Also, if you have a dog that is prone to getting a lot of ticks and fleas, then again, the product might last for fewer than eight months. This is true for dogs that love to walk in tall grass.

Another great feature of this tick prevention collar is that it is completely odorless. This means that you don’t have to endure any pungent or unpleasant smell that other flea and tick collars might have.

As opposed to other similar products, the Seresto flea and tick treatment does not have to be stretched for activation. As soon as you put the flea collar on your dog, it is automatically activated, and the ingredients quickly spread throughout the body of your dog.

Within 48 hours, it kills adult fleas, and you can simply comb away the dead fleas later on.

Seresto also has an additional feature: a safety reflector that can be attached to your dog to help keep it visible at night. If you have a dog that loves to go for a walk at night, using an LED dog collar is a great idea to keep your dog visible in the dark.

My dog is very active and playful, so the thing I was most worried about was whether or not the collar would still be effective if it got dirty or muddy. The answer is no, it doesn’t.

The two slow-release active ingredients still work their magic despite it being covered in mud. All I have to do is simply wipe the flea collar with a moist cloth as soon as playtime is over – or whenever I get the chance.

When it comes to hyperactive dogs, you don’t have to worry about breaking or damaging the collar. For instance, in case your dog is wearing the collar and gets hung up on one of the kitchen cabinet doors, he can easily pull back and release the Seresto flea collar very quickly without breaking it.  

Although available in two sizes, for small and large dogs, the collar is very adjustable. The product can be used for dogs that are 6 weeks old or above. My 85-pound German shepherd fits in large sizes. For dogs under 18 pounds, the small dogs’ version would be the best fit.

Seresto flea collar specifications for small dogs:

  • Neck Size: 13.25” or 30.48 cm
  • Dog Weight: Under 18 pounds

Seresto flea collar specifications for large dogs:

  • Neck Size: 27.5” or 69.85 cm
  • Dog Weight: Over 18 pounds

All in all, Seresto collars are the perfect option to get your dogs tick-free. They not only get rid of the existing flea eggs and ticks but also prevent any future infestations. This means that your dog’s coat will be safe from flea bites.

Is Seresto Dog Collar Safe?

Seresto dog collars are absolutely safe to use for your dogs. If your dog doesn’t normally wear a dog collar, there might be a case of skin reaction such as redness, itching, hair loss, or skin irritation.

These symptoms will disappear in a week or two if you don’t remove the Seresto flea collar and your dog develops a habit of wearing one.

If the symptoms are visibly severe, it is recommended that you remove the collar until they get better. In a few cases, Seresto collars have led to reactions such as lesions, eczema, inflammation, and dermatitis.

Other dog owners have reported cases of nausea, vomiting, seizures, red eyes, and swelling. However, these incidents are very rare.

The flea collar is developed by the Animal Health unit at Bayers, which is a well-known and reputable company operating as early as 1863. This adds to the authenticity of the product. The collar is marked safe to use by veterinarians and still ranks highly recommended.

How To Apply a Seresto Tick and Flea Dog Collar?

The thing I love the most about the Seresto flea collars is how convenient and easy it is to apply.

Take out the Seresto collar from the tin and remove the protective plastic bag before use. Unroll it and remove the remnants from the plastic connectors inside the flea collar. Now place the collar on your dog’s neck and clasp the buckle.

The size of the Seresto collar can be adjusted using the ratchet mechanism by feeling the collar through the loops until a comfortable fit is achieved. Make sure that you can fit two fingers beneath the collar so that it is not attached too tightly.

It is especially important to periodically adjust the fit of the collar for a growing puppy. Any excess length of the collar beyond two centimeters should be cut off.

When it comes to the safety reflectors, they must be attached to the non-overlapping part of the Seresto flea collar to ensure the safety mechanisms are not blocked.  

Simply follow the steps mentioned above, and you’re good to go! Your dog is now protected against fleas and ticks for eight months. It is recommended to replace the collar as soon as it is nearing the end of the eight-month tenure.

There is no need for you to wait for a little while, in between switching collars. It is also advised to check the effectiveness of the Seresto flea collar towards the end, just to double-check that it is still doing its job.
