If you spend much time outdoors and have a dog or two, perhaps you will agree that ticks are the bane of our existence. They are a constant, ubiquitous threat to our health and sense of well-being. And, to make things worse, their numbers are increasing according to scientists.
Unfortunately, there’s little we humans can do to prevent these dreaded ticks from making their way onto our bodies—we just have to constantly check for them upon returning from our outdoor adventures. And, we keep our fingers crossed we didn’t miss those microscopic nymphs that are all but invisible to the naked eye.
The good news is, the Seresto® collar is an effective tick repellent for dogs—it not only eliminates ticks, but also gets rid of fleas and flea eggs on dogs.
Fellow dog owners rave about the Seresto Collar, claiming it’s more effective than the other flea and tick preventative products they’ve used, especially since it’s practically foolproof. They explain that it’s convenient and not prone to ‘user error’ since it doesn’t involve any messy, monthly topical applications they must remember. And it can last many months before it needs replacing. Many veterinarians recommend it as well.
How Does Seresto Actually Work?
The Seresto Collar comes in two sizes—large or small—and is sized to fit your dog’s neck similar to an ordinary collar. It contains two active, odorless chemicals—imidacloprid (for fleas and their eggs) and flumethrin (for ticks)—which are embedded in the plastic collar and released in low concentrations and distributed over the dog’s body on a sustained basis for up to eight months. These chemicals have been clinically proven to kill fleas and ticks on contact—no bite necessary—within a matter of hours.
The collar starts killing the existing fleas on your dog within 24 hours and ticks within 48 hours, and then kills or repels fleas and ticks within a few hours to prevent new infestations. Remove any embedded ticks from your dog’s skin before putting the collar on—already-embedded ticks may remain attached even after the Seresto Collar has started to work.
Compared to other flea and tick collars on the market, Seresto is longer lasting and continues to work even after it has gotten wet. And it eliminates all fleas and ticks from the dog’s entire body, not just those near the collar. It is different also because it eliminates adult fleas as well as their larvae, interrupting the fleas’ life cycle—which prevents reinfestation and keeps eggs and larvae out of bedding. It works more quickly than competing products, reducing the chance of tick-borne disease transmission. Finally, because there’s no need to remember to reapply Seresto, it’s more reliable than Frontline® and other topical solutions.
Seresto Collars contain the same or comparable chemicals included in other flea and tick treatments such as Frontline and NexGard, but you probably shouldn’t use them at the same time. Experts warn that dual usage poses a risk of overdose toxicity—a serious reaction to a medication overdose. Consult a veterinarian prior to changing or combining flea and tick spot or oral treatments with a Seresto Collar.
The collar is not effective against heartworm infection; your dog still requires an ongoing heartworm preventative, as prescribed by your veterinarian.
How Long Do Seresto Collars Last?
A controlled release of the infestation-fighting chemicals in Seresto Collars means the flea and tick prevention lasts for up to eight months with only one application. That’s easier—and more reliable—than topical treatments you must remember on a monthly basis.
The Seresto Collar works only when your dog is wearing it. Taking the collar off at night, removing it during the day, or putting it on him only when you go outside may decrease its effectiveness, as the cumulative release of chemicals is what keeps fleas and ticks at bay. For the best protection, leave the collar on your dog.
Can the Seresto Collar Get Wet?
We know how hard it is to catch our water-loving canines before they leap into the pond, but there’s no reason to remove the collar for a swim. The Seresto Collar is water-resistant, so it’s effective even if it gets wet. It will continue to repel and kill pests even after your dog goes swimming, is bathed, or gets caught outside in the rain. While water-resistant, it’s not waterproof: It can stand up to a dunking here and there, but repeated water exposure will shorten the life of the collar slightly depending on frequency. The manufacturer suggests that bathing or swimming more than once per month can reduce efficacy to five to seven months. Consult the manufacturer’s product information for details.
There Are Ticks on My Dog—Is the Collar Working?
Because the Seresto Collar works through contact, it’s possible for your dog to pick up fleas and ticks while you’re out on a hike—but the collar repels or kills the bugs before they’re able to bite. You can double up protection by brushing your dog after a walk through grassy or wooded areas.
Is the Seresto Collar Safe?
Veterinarians consider the Seresto Collar a safe preventative against fleas and ticks and not harmful to adults or kids—but the manufacturer’s safety paperwork offers a few precautions.
- Owners are reminded to wash their hands after handling or putting the collar on their dog.
- Because the collar includes small pieces that are choking hazards and the plastic is impregnated with insecticides, children should not be allowed to play with, wear, or handle the collar.
- Adults and children should wash their hands after playing with a pet who is wearing a Seresto Collar.
- Don’t put the collar in your mouth or allow children to chew on it.
- Chemicals are contained within the Seresto Collar’s plastic, so contact with the collar isn’t harmful, but chewing on or ingesting it can cause stomach upset, vomiting, lethargy, or a blockage—contact your vet if you suspect your dog has ingested any part of a flea collar.
- The manufacturer and veterinarians recommend against using Seresto Collars for pregnant or lactating dogs or for puppies younger than seven weeks.
- The collar is intended for dogs only; veterinarians don’t recommend using Seresto Collars for other animals due to the risk of overdose or adverse reactions.
As a safety consideration, the collar is designed to break off if it gets caught on something while your dog is wearing it. And, it comes with reflectors you can attach to make your dog more visible at night. The Seresto Collar is not meant to replace your dog’s regular collar with ID. Alternatively, you could outfit your dog in the personalized side-release collar to which the Seresto Collar can be attached.
What About Side Effects?
According to the manufacturer, Seresto has been tested extensively for safety. Reported side effects include allergic reaction, lethargy, localized skin irritation, and hair loss on the dog’s neck. The safety information included with the collar indicates removing the collar and bathing your dog thoroughly if any signs of irritation occur. Because some dogs are more sensitive than others and there are many factors to consider, it’s best to consult your veterinarian with any questions or concerns before using Seresto or any other medication.
There is no perfect solution when it comes to finding an effective flea and tick repellent for your dog, but Seresto is a proven deterrent. Its effectiveness is owing in large part to its ingenious design, which makes it especially easy to use. Now if only there were as reliable a way to keep ticks off of humans! Or, better yet, a way to keep ticks well away from all of us.
