There's a Tick on Your Dog Right Now That He Can't Feel — and Can't Tell You About.
You give the chewable. You check his coat. You still pull ticks off him — because the threat changed and the playbook didn't. The monthly pill works from the inside out, but there's a gap before the bite — and here's what every dog owner should know before another season of after-walk tick checks.
My name is Daniel Reeves. I'm an industrial designer, I live in western Connecticut, and I'm the owner of a five-year-old Lab named Scout who tested positive for a tick-borne infection after a bite we thought we'd handled.
I spent fifteen years designing consumer hardware — health wearables, outdoor electronics, the kind of products that end up at REI. I am not a veterinarian. I am not an entomologist. I'm the guy parting his dog's fur under the kitchen light after every walk, the same as you.
What I am is the guy who spent eighteen months on the phone with Lyme researchers in upstate New York, entomologists at UConn, and Scandinavian veterinarians who have been quietly recommending ultrasonic clips for working dogs for over a decade. I logged hundreds of hours of conversations with dog owners across the country who told me the same three things:
- 1"I do everything right and I'm still pulling ticks off him."
- 2"I hate putting another chemical on my dog — but I hate Lyme more."
- 3"He can't tell me when something's wrong."
That's what I built PULSE for. Not "bug bites." That. The worry that never fully switches off. The lump under the fur at 11:14 p.m. that turns out to be nothing — and the one time it isn't.
You've given the monthly chewable. You've fastened the medicated collar. You've done the after-walk comb, the run-your-hands-over-every-inch, the check behind the ears and between the toes. You've paid $640 for the yard service that doesn't extend to the trail. You've thrown out a clip-on whose battery died in a drawer, and a "natural" spray you knew in your gut was theater.
You've sat in the vet's office hearing "let's run a tick panel" and not slept right since.
You name it. I've heard it. From thousands of dog owners who look exactly like you, in towns that look exactly like yours, who are doing everything right — and still pulling ticks off their dogs. You are not the paranoid one. You're the careful one.
A Tick Bite Isn't Just an Itch… It Can Steal Your Dog's Energy, His Joints, and Years Off His Life — Silently, One Bite at a Time.
Here's what nobody told you, and it's the single piece of information that reframes every chewable, every collar, every after-walk comb you've done in the last five years.
The rules of tick protection you grew up with don't apply anymore. The deer tick. The "stay out of tall grass." The tick check at the end of the walk. All of that was built for one tick — the blacklegged deer tick — and mostly one disease, Lyme. That tick had rules. It was a passive quester. It climbed to the top of a blade of grass, held out its front legs, and waited. You could see it. Check for it. Manage it.
That tick is still here. But it has company now. The Lone Star tick — once a quiet Southern pest — has swept north into Connecticut, Massachusetts, New York, Pennsylvania, Michigan, Wisconsin, and into places that twenty years ago would have laughed at the idea. And the Lone Star tick does not wait. It hunts. Entomologists call them "aggressive questers." They actively track the carbon dioxide your dog exhales. They cover ground the deer tick never could — across the yard, down the trail, straight toward your dog.
And the ticks crawling through your dog's coat right now can carry Lyme disease, anaplasmosis, ehrlichiosis, and more — infections that can quietly damage his joints, his kidneys, and his blood for the rest of his life. The hard part: dogs often show nothing at all for weeks or months. By the time he's limping, off his food, or running a fever, the tick is long gone — and you never saw it.
So if you've been giving the chewable, checking his coat, and still finding ticks — it's not because you've been doing it wrong. It's because you've been doing it outdated. The playbook you inherited was written for a world that no longer exists. The threat changed. The defense didn't. You're the first generation of dog owners defending against ticks that hunt, in places they never used to live, carrying diseases your dog can't tell you he has.
That's the gap. And until somebody closes it for you, no amount of vigilance is going to give you back the easy walk in the woods.
There is a way to close it. It doesn't come from a chemical company. It doesn't come from the pet-store shelf. And it's been sitting in European veterinary research for over a decade…
The Layer of Tick Defense Working Dogs in Europe Have Used for 15+ Years — That Almost No American Dog Owner Has Heard Of.

I bought four. One for the dog's collar, one for the second dog's harness, one for my husband's hunting vest, one for my own daypack. I'm the one who reads everything before I buy — I read the Haller's organ research first. What sold me wasn't the science — it was that the founder said outright "this works WITH your vet's tick prevention, not instead of it." Six weeks in, both dogs still get their monthly chewable. The after-walk check still happens. But the between moments — the dawn walk, the romp through the tall grass behind the house, the hour in the yard before dinner — those used to be the gaps I lay awake about. Now they're covered. I'm not saying I've stopped checking. I'm saying I stopped catastrophizing. That alone was worth four units.
Ticks don't see the way you do. They are nearly blind. What they have instead is a tiny, exquisitely sensitive sensor on their front legs called Haller's organ — and this is where the entire story of modern tick defense gets interesting.
Haller's organ reads the world through vibration, heat, exhaled CO₂, humidity, and a very narrow band of ambient frequencies. It's how a tick on a blade of grass — or a Lone Star tick actively quartering toward your dog across the yard — knows that a warm-blooded mammal has entered its airspace. It's how it decides whether the passing target is worth latching onto. Haller's organ is the tick's entire targeting system. Without it, the tick is a blind insect on a leaf. With it, the tick is a guided projectile.
Here's the part that almost no American consumer has been told: Haller's organ is also the tick's single greatest vulnerability. When a specific ultrasonic frequency band — between roughly 9 and 21 kHz, completely inaudible to humans, dogs, and cats — is introduced into the tick's sensory field, the organ effectively short-circuits. Researchers describe it as "sensory static." The instruments go haywire. The dog it was hunting no longer reads as prey. The tick disengages and looks elsewhere. You don't kill it. You don't poison the environment. You don't put anything on your dog's coat. You make your dog invisible to the part of the tick that decides who to bite.
So the solution comes down to two things — and they're simpler than the marketing of this category has ever made them sound:
Keep doing what already works.
The monthly chewable or topical from your vet. The medicated collar. The after-walk tick check. The yard treatment. None of that goes away. The CDC, ILADS, every credible voice in tick research — and every good vet — agree: no single defense is one hundred percent. Layer up.
Close the gap with the layer that's been missing.
The first hours of a new bite before the chewable can act on it. The dog who licks at a topical. The puppy too young for some products. The walk at dusk when a tick climbs aboard. This is where the chemical playbook leaves a gap — and it's exactly where a non-chemical, sensory-disruption layer was engineered to live.
For years, the only people running this play were European veterinarians. The big chemical brands had no incentive to tell you — there's no chewable to refill, no collar to replace twice a year, no repurchase cycle. So the research sat there. Until a Connecticut dog owner, after his own dog tested positive, decided to bring it across the Atlantic — redesigned to clip to any collar, harness, or vest.
PULSE doesn't use a blend of ingredients. It doesn't use ingredients at all. It uses physics.
Inside the 11-gram, guitar-pick-sized housing is a precision ultrasonic emitter calibrated to a wide-band frequency between approximately 9 and 21 kHz — the exact range that disrupts the Haller's organ of ticks, including the aggressive Lone Star tick now spreading north, while sitting above the comfortable hearing range of human adults and outside the sensitivity peaks of dogs and cats. Your dog won't react to it. Ticks will.
This calibration didn't come out of a guess. It came from eighteen months of conversations with veterinary researchers in Sweden and Hungary who have been quietly observing this principle in working-dog populations across Scandinavia and Central Europe since the early 2010s. Their data, their field reports, their frequency curves — translated, redesigned, and rebuilt into a clip light enough to ride on any collar or harness without your dog noticing it's there.
It runs continuously for 2 to 4 days on a single 1-to-2-hour USB-C charge. It has one button. No refills. No chemicals. No scent. No reapplication. No melting watch bands. No "did I get behind his ears?" The reason you've never heard of this isn't because it's new. It's because nobody built the version for your dog — and the whole household he lives in — until now.
Introducing PULSE™
An ultrasonic tick-deterrence wearable engineered to clip to your dog's collar or harness — and quietly help protect the whole household he lives in.
Over 30,000 dog owners across the Lyme belt and Lone Star expansion zones have already clipped one onto a collar, a harness, a hunting vest, a leash loop. They include suburban owners walking labs at dusk. They include hunters who've pulled more ticks off their bird dogs this season than in forty-six years afield. They include people whose last dog suffered through tick-borne Lyme — and who do not intend to watch it happen again.
Available in your choice of Black or White — pick the one that looks best clipped to his collar.
I'm the dog owner you don't want next to you at the trailhead. I send the tick-map screenshots. I check him head to tail after every single walk. My husband thinks I'm unhinged about it. He's not entirely wrong.
I grew up in Old Lyme — yes, that Old Lyme — with dogs running the woods behind the house. My golden, Murphy, got Lyme nephritis at seven. We lost him at eight. I have been quietly carrying that for years.
By the time I found PULSE, I had cycled through everything. The monthly chewable (we still give it). The topical (he licked at it). A medicated collar. A Tickless clip whose battery died on a hike two years ago. The $640-a-season yard service. So many tick combs.
What broke me was last August. My current dog, Biscuit, ran a fever for two days and I couldn't find a reason. The vet ran a tick panel. I have not slept right since.
What sold me on PULSE was three things. One — the founder is a dog owner whose own dog tested positive. That's not a marketing story. That's my nightmare in someone else's house. Two — the page didn't promise me 100% anything. It said "the layer you've been missing" and explained Haller's organ in language I didn't have to Google twice. Three — the 99-day guarantee.
I bought four. One for Biscuit's collar. One for the puppy's harness. One for my daypack. One for my husband's hunting vest.
"The monthly chewable still happens. The after-walk check still happens. But the background process — the dread that's been running in my head every walk for years — has quieted down."
Last Saturday I let Biscuit run the tree line at dusk and didn't immediately march him to the porch light to check him. I teared up a little. My husband didn't notice.
I'm not telling you PULSE is a miracle. I'm telling you it's the missing layer. And the missing layer was where my brain was living.
Forty-six years of running dogs in this state and I've never seen tick numbers like this season. My old hound, Gus, went down two falls ago — anaplasmosis. Wouldn't eat, wouldn't get up, bled from the gums. Vet bills ran four figures and we damn near lost him. The dog lives to hunt, and the ticks were trying to take him from me.
I'm a chewable-and-collar guy. Always have been. I'm not the target customer for some clip-on gadget and I want to be honest about that.
What changed my mind was the founder's positioning. He said outright: don't stop the chewable. PULSE is the added layer. For the hours before a fresh bite takes the medicine. For the pup too young for the pill. For the dog who licks the topical off. For the walk at dusk. He wasn't trying to replace what my vet prescribes — he was trying to cover what it can't.
Bought one for Gus's collar. One for the young dog. One for my pack. One for my wife's lab.
"Three weeks of clipping it to his vest and I pulled a fraction of the ticks I used to off him. That alone was worth the money."
My wife says the dogs don't seem to mind it at all — can't even tell it's running. And neither of them has dragged a tick into the house in a month and a half.
I'm not throwing out the chewable. I'm clipping PULSE next to it.

Remember… He Can't Do This Part Himself.
It's about the dog who can't tell you his joints ache — who just slows down, and you blame it on age.
It's about the early-morning walk through the grass you can't pre-treat.
It's about the tick he carries back inside — onto the couch, the bed, the kids.
It's about the partner who thinks you're "too much about this" — who would think differently if they'd sat where you sat at the vet last August.
It's about the version of him that runs the tree line flat-out — that you'd like to keep for as many years as you can get.
You can't make the Lone Star tick go back south. You can't undo a bite he already took. You can't change the fact that the rules shifted underneath us while we were busy being good owners with the tools we were handed.
But you can close the gap. Tonight. Before the next morning walk. Before the next romp in the tall grass. Before the next lump under the fur at 11:14 p.m.
You've been the careful one. You've been the "paranoid" one. You've been the one carrying the worry alone.
Clip one on his collar. Take a breath. Let him run.
Frequently Asked Questions
Everything you need to know about PULSE™ Ultrasonic Tick Repellent
PULSE™ emits a precisely calibrated ultrasonic frequency that is imperceptible to humans and pets but highly disruptive to ticks and other parasitic pests. The ultrasonic waves interfere with the tick's sensory organs, helping deter them before they latch on. Simply clip it to his collar, switch it on, and let him enjoy his time outside — no sprays, no chemicals, no mess.
Absolutely. PULSE™ operates at a frequency completely outside the comfortable hearing range of dogs and cats — your dog won't react to it or be bothered by it. There are zero chemicals, zero toxins, and nothing for him to lick or absorb. You can clip it to his collar or harness with total peace of mind — and a second one to your kid's backpack or your own pack just as safely.
PULSE™ features a long-lasting rechargeable battery that provides up to 120 hours of continuous protection on a single charge. That means weeks of daily outdoor use before you need to plug it in. Recharging takes approximately 2 hours via the included USB-C cable. A low-battery indicator light lets you know when it's time to recharge.
PULSE™ provides a protective radius of approximately 10 feet (3 meters) in all directions from the device. Clipped to the collar, that creates a personal tick-deterrence zone right around your dog. For larger areas like a campsite or a kennel run, many owners use two or more devices to extend the coverage zone. One unit is typically enough for a hike, a hunt, or a daily dog walk.
Many dog owners come to us because they're uneasy about adding another chemical month after month — topicals that rub off on the couch and the kids, collars that sit against the skin, chewables some dogs react to. PULSE™ adds zero chemicals. It deters ticks with sound waves, not poisons, and there's nothing for your dog to lick off. It's reusable (no monthly repurchase), waterproof, and works the moment you switch it on. Important: we always recommend keeping the tick prevention your vet prescribes — PULSE™ is built to work alongside it as an added layer, not to replace it.
Yes! PULSE™ is rated IP65 waterproof, meaning it can withstand rain, splashes, and morning dew without any issues. It's fine on a rainy walk, through wet grass, or while your dog splashes around the edge of a creek. We don't recommend submerging it for extended periods, but normal outdoor conditions are no problem at all.
We stand behind PULSE™ 100%. If you're not completely satisfied with your purchase for any reason, simply contact our support team within 99 days of receiving your order. We'll issue a full refund — no questions asked, no hoops to jump through. We even cover return shipping. That's how confident we are that PULSE™ will change the way you experience the outdoors.
Orders placed before 2 PM EST ship the same business day. Standard shipping typically takes 3-5 business days within the United States. Expedited and express shipping options are available at checkout. You'll receive a tracking number via email as soon as your order ships so you can follow it every step of the way.
While PULSE™ is specifically tuned and optimized for ticks, many owners report it also helps deter fleas, mosquitoes, and other biting insects around their dog. The ultrasonic frequency disrupts the sensory navigation of multiple pest species. That said, our primary engineering focus and testing has been on tick deterrence, where it delivers the strongest, most reliable results.
Don't Wait for a Tick Bite to Take Action
Give your dog a chemical-free, ultrasonic layer of tick defense — and cover the whole household while you're at it. One device. Zero toxins. A full 99 days to try it risk-free.
