“The Dewel natural collar is one of several natural preventative I use on my 11 yr old shih tzu. Our home is in a wooded area, and only 5 min from the beach, so he needs extra protection bc he is outside a lot in both environments. I am very pleased with the effectiveness of this collar and love the scent when it is new!”

I’VE READ THAT SOME ESSENTIAL OILS CAN BE TOXIC TO CATS. IS THIS COLLAR REALLY SAFE?
WHY ARE YOUR NATURAL INGREDIENTS SAFE WHEN OTHERS SAY THEY’RE DANGEROUS?
It comes down to dosage and delivery. DEWEL™ uses essential oils like Lavender and Lemon Eucalyptus in diluted, stabilized amounts that repel pests — without harming your pet. Unlike raw oils or DIY mixes, our formula is specifically engineered for pet skin safety. It’s even been tested on small-breed dogs and puppies over 8 week
WILL THIS CAUSE ALLERGIES OR SKIN IRRITATION?
Unlikely. The ingredients are plant-based and chosen for their low risk of irritation. If your dog has very sensitive skin, monitor for the first 24–48 hours. We also offer a full refund if it doesn’t suit your dog.
WHAT IF MY PET LICKS THE COLLAR?
Collars release oils at a very low rate; incidental licking is harmless. No adverse reactions have been reported in over 5000 uses.
IS THIS SAFE FOR ALL DOG BREEDS AND SIZES?
Yes! DEWEL™ collars are designed for all dog breeds and sizes, from tiny Chihuahuas to large Labradors. Just trim the collar to fit snugly but comfortably. The plant-based formula is non-toxic when used as directed.
WHAT ARE THE ACTIVE INGREDIENTS USED IN THE COLLAR?
The collar contains a carefully selected blend of natural ingredients, each with its unique benefits for your pet:
TPE (Thermoplastic Elastomer): Comprising 78% of the collar's composition, TPE is a durable and flexible material.
Cinnamon Oil (5%): Cinnamon oil is known for its insect-repelling properties, keeping fleas, ticks, mosquitoes, larvae, and lice at bay.
Eucalyptus Oil (5%): Eucalyptus oil serves as a natural insect repellent and has antimicrobial properties, offering protection against various pests.
Lavender Oil (3%): Lavender oil is included for its antibacterial and anti-itch properties, helping soothe your pet's skin and promoting healing.
Lemon Eucalyptus (3%): Lemon eucalyptus oil acts as a natural insect repellent and has a fresh scent, contributing to a pleasant aroma around your pet.
Linaloe Oil (6%): Linaloe oil is included to provide additional benefits and fragrance.
These ingredients work in harmony to protect your pet from a range of pests and offer soothing and healing properties for their skin. Your pet will not only enjoy the benefits of this collar but also the natural and refreshing scents it imparts.
HOW OLD SHOULD A PUPPY/KITTY BE TO PUT ON THE COLLAR?
Once your puppy or kitty reaches 8 weeks of age, you can begin using the collar.
CAN I TRIM THE COLLAR IF IT'S TOO LONG FOR MY PET?
Yes! The DEWEL™ collar comes in one adjustable size and can be easily trimmed to fit dogs or cats of all sizes. After fitting it comfortably around your pet’s neck, just cut off the excess length — simple, safe, and customizable.
WHAT'S THE TOTAL LENGTH OF THE DEWEL COLLAR?
The length of our product is approximately 62cm/25 inches, making it a one-size-fits-all option. If needed, you can easily trim any excess using a pair of scissors to achieve your desired fit.
HOW OFTEN SHOULD I REPLACE THE COLLAR?
The ingredients are active for up to 8 months, at which point you should invest in a replacement. Please keep in mind that if you live in an environment where the flea infestation is so strong, then the lifespan of the collar can be reduced drastically, and you'll need to buy a new collar more frequently until the lifestyle of the fleas breaks for good.
DOES THE DEWEL COLLAR HAVE AN EXPIRATION DATE?
No, the collar does not have an expiration date.
IS THE COLLAR WATERPROOF? CAN MY PET SWIM OR BATHE WITH IT ON?
Absolutely. The DEWEL™ collar is 100% waterproof, so your pet can safely bathe, swim, or play in the rain without losing protection. The active ingredients remain effective even after exposure to water — no need to remove the collar!
CAN I USE THIS COLLAR WITH OTHER FLEA TREATMENTS OR MEDICATIONS?
Yes, you can. The DEWEL™ Flea & Tick Collar is made with natural, non-toxic ingredients, so it's generally safe to use alongside other flea treatments like shampoos or oral medications. However, if your pet is on prescription meds or has a medical condition, we recommend consulting your vet first.
HOW FAST DOES THE DEWEL COLLAR START WORKING?
You’ll begin to see results in as little as 24–48 hours. Most users report a drastic reduction in scratching, fleas, and ticks within 2–3 days.
HOW IS THIS DIFFERENT FROM SERESTO?
Seresto uses synthetic insecticides, while DEWEL™ relies on a natural, plant-based formula that’s gentler on pets and families. It’s a safer alternative without compromising effectiveness.
WHAT IF IT DOESN’T WORK FOR MY PET?
No worries! We offer a hassle-free guarantee. Just reach out within 90 days, and we’ll send a free replacement or give you your money back. No questions asked.
