“The dog collar was received very quickly so that was a huge plus. The natural collar from dewel pro is just as advertised and has a very smell like citronella. My dog doesn’t mind the band and was very large so if you have a larger breed plenty of room to fit around neck.
My BM/GS could have almost cut in half with the size to have two. Just put it on and have noticed no itching or biting and will monitor in the coming weeks to months. This is my 3d time using this product and think it works great for the price and have not had any issues regarding it. It seems to last around 6 months to repel flees and ticks. I usually replace every 6 months. Have never gone past that time frame so cannot comment on the length it could or would last.
Very happy and certainly will purchase again and highly recommend for anyone who doesn’t want the expensive monthly meds and or deal with the cheap chemicals that take days to dry on your dogs fur while possibly getting over your house or items when applied.”

“Chemical free is always a bonus! Love that the smell isn’t full of chemicals. It’s durable and thick. Comes long enough for all neck sizes. These dog collars form Dewel pro are great deal for the price!”

“I really like this natural dewel collar . When I got it I thought it would be strong smelling, but it wasn't. My dog has very short hair so I needed to find an organic collar that wouldn't irritate his neck. No irritation. I was using an all organic squeeze on that works great, but made Rosco smell like a baked ham for a day, which wasn't bad. Wanted to try something different. We are just getting into tick season and so far so good. The real test will be when the woods around us dry out more and he starts to roam around in them.”

“So I have a long haired chihuahua and a 100# Rottweiler. We recently started having stray cats show up outside. Apparently the cats brought hundreds of new friends with them aka bad bugs. My dogs have always been on frontline and we’ve never had an issue. But this year they were eating theirselves alive.
My Rottweiler lost most of his hair due to chewing. The vet did skin scraps and said it was allergies. So we put them both on Benadryl on top of the “vets best seasonal allergy” pills. Vet had Rottweiler on 6 Benadryl a day and 4 vets best. The scratching would NOT STOP. Keep in mind, I searched them constantly and never found any. I ordered 2 an put them on them both of my dogs a week ago today.
They have 100% stopped scratching. My rotties hair is growing back in and they both slept for what seemed like 2 solid days due to not ever sleeping from the constant scratching. I took them both off the allergy pills 3 days ago and the vets best. Still no scratching. I don’t know what kind of magical potion they use but they definitely worked for my 2 fur babies! I’ll never let them go without this again.”

“I rarely write reviews but the Dewel Pro collar warranted my time. Those of us with who genuinely care about our pets are always on the lookout for the best way to keep them safe and happy.
After all, they're members of our family! Having bred champion German Shepherds for nearly twenty years, we'd heard more than a few horror stories regarding harsh chemicals used in some collars.
We've always recommended using products with all-natural ingredients. The organic collar smells great, fits all sizes of dogs, is very reasonably priced and, most importantly, is extremely effective. Pictured is our sweetheart, Kona.
She'd been wearing her last dewel pro collar for eight months and, to be honest, we weren't entirely sure that it needed to be replaced. Not wanting to take any chances, however, we ordered a new. Having tried several other alternatives over the years, we can give this product our highest recommendation.
Of course, as with any treatment, there is always the possibility of an allergic reaction. Nobody we know personally has had any issue whatsoever with the dewel pro collar but, if you truly care about your pet, always watch them closely for any changes in behavior when trying something new. Great job, DEWEL PRO! We look forward to using your product again and again .”

“ This collar from Dewel pro seems to do the trick. Had it for about a month now. I run with my pup on heavily wooded trails in FL quite often. Luckily, I always check him for tick(s) right afterwards. This time of year seems to bring in a ton of them and since I’ve had the collar I have still found them on him”
Waiting to worry about fleas and ticks until an infestation strikes can lead to pain, suffering and unnecessary vet bills! Our dogs deserve better. Preventative measures can cost just a few dollars per month!

How Can I Be Sure This Collar Will Fit My Dog?
Is DEWEL PRO Collar Waterproof?
Absolutely! Although submerging in water for long periods will reduce performance. We'd recommend removing the collar before your dog swims or bathes.
How Often Should I Replace The Collar?
The ingredients are active for 8 months, at which point you should invest in a replacement.
How Should The Collar Be Worn?
- It should fit snugly and make contact with the skin
- Make it's sure the dog cannot remove it
- Follow the two-finger rules to keep your dog easy
- Always cut off the addition length
- Dispose off cut off pieces carefully and do not allow to fall it in the hand of kids
- Keep monitoring your dog for skin irritation and hair loss
- Change the collar after 8 months when it becomes ineffective
