We live in SE Houston and the coastal fleas have become mutant super villains bent on world domination. Frontline stopped working completely. Advantage II only works for a week at a time-- too much cost and chemicals for your pup. I was starting to think Kona would just have to endure a lot more baths when I talked to a breeder about what she uses for her show dogs. Instantly she replied "DEWEL PRO flea collar. Trust me, you'll be glad you did."

The first day I combed her and found a few dying fleas. It took about a week before I stopped finding any at all, alive or dead. Give it some time to work and realize you probably have a lot in the environment that need to have the opportunity to jump on your pet and die. Good riddance!

UPDATE: When our second dog (golden retriever puppy) rapidly outgrew his size small, we got him the larger collar. Within a few days, I could feel little bumps around his neck and knew it was an early sign of a reaction. I attribute this to the greater width of the new collar and the fact that he still has some "puppy fluff" instead of all is adult fur yet. The bumps have since scabbed up, but they are very minor except for causing him some discomfort and making him want to scratch often.

Kona (small mutt!) still has no issues whatsoever. I am not changing my review from five stars because this flea collar WORKS when nothing else has been on our fleas. We will try again with our golden when he grows some more fur coverage and update again.

I’ve been purchasing this flea collar for my Siberian Husky every 5 months for over 4 years. It works EXCELLENT! He has NOT had a problem with fleas or ticks since our Vet recommended this collar. I found at 5-1/2 months he would begin to scratch and chew.

So I have this flea collar for dogs automatically sent every 5th month and he has not had a problem since. The package says it is good for 8-months and perhaps on a smaller breed (where the distance from his tail to his collar is not so great) it may well last 6 months or longer. But for my large Husky I found 5 months to be time to swap in a new one. NOTE: When I bath him or he goes for a ‘spa day’ (lol) I REMOVE the collar and put it right back on him as soon as I finish brushing him out. Well worth keeping him healthy and flea/tick free.

Side note, we have a 21-acre ranch filled with brush though he is an inside dog, he does go out whenever he needs to for pleasure or for business. Sometimes roaming our ranch for hours. Yet never has he brought home one fleas or ticks (and there are plenty of both here!

We first used the flea collar after recommendation from the vet . We live in the country and my great Dane was covered in ticks. It not only kills them but repels them as well. If a flea and tick medicine doesn’t repel them it(s useless to me. But this flea collar repels. Once they wear it we have NEVER found a tick on them. This last longer than 7-8 months. We only replace it one a year. We put it on in April and then they wear it year around. Gone are the days of forgetting to put their monthly medicine on that leaves a nasty residue on their back. We have small kiddos and this a safe. No odor like traditional flea and tick collars. We will never go back to frontline or any other flea medicine. Dewel pro is literally the best flea collar for dogs. Period.

I got this flea collar for my (not so) little cuddle buddy and I was not disappointed. Boone is usually the most docile dog, but for some reason, he HATES flea collars. It's like a war to get them on him. However, with all his cute wrinkles and rolling in the leaf pile shenanigans he needs them to stay healthy and safe. This natural flea collar was at the right price with mostly positive reviews so I thought, why not take a chance? I'm so glad I did, I'll never use anything else.

Over a month later and we are still flea free. Not only does this flea collar work, but it was also super easy to put on my little monster. Mostly I think that was because it doesn't have an overwhelming chemical smell like a lot of the other flea collars out there. Usually, Boone whines and runs from the smell of the collar. This one form dewel pro he just sniffed and sat there looking at me like, what?

Definitely worth a try. What do you have to lose? 10/10 would recommend.

Great delivery time I was impressed! I have a  flea collar on both my dogs a little strong for the first few days then good. I haven’t seen anything on my dogs so I’m super happy and even the mosquitoes aren’t bugging them. To say the least “I’m happy!”

This flea collar has been the only solid protection my animals have had against Florida pests. Drops from the vet didn't work, but this flea collar works great. We purchased one for our Saint Bernard puppy and our older Boston Terrier mix. Now, if it could keep the ants from biting them, I'd be even more excited. :)

These are worth the money. My animals do great with them and I don't have to worry about the kids touching them. My animals hated the liquid, this flea collar is convenient, safe, effective and all around great. Barely noticeable. We've been in heavily wooded areas and gotten ticks but the animals didn't. I have a long-haired cat, Maltese dog and large boxer mix (as pictured)- I use flea collars on them all. It says 9 months but I change collars every 12months.

I can NOT praise this product enough. My husband and I fostered two 4 week old kittens. At that age, they're too young for flea medicine so when I brought them into my house, I also brought in LOTS of fleas, and gave them a nice home because my house is mainly carpeted.

I was getting flea bites, and my dog was scratching- I felt like such a monster doing that to him. After we got those cats adopted, we got the house sprayed for fleas and I gave my dog a bath in dawn dish soap and hand plucked all the fleas off of him. (Took hours) But alas, all of the dead fleas were replaced by alive ones. Got my house sprayed again, then a third time along with getting my dog COMPLETELY shaved.

Then my friend recommended the DEWEL flea collar. Within a week, my dog was no longer scratching and I was no longer being bit! This is totally rocked my world and did the impossible. I was so hooked I immediately bought the cat flea collar when I got my cat. Thank God for the DEWEL PRO flea collars!

I have two pit boxers, recently their outdoor enclosure became infested with fleas and the dogs had them bad. We lie in the woods so ticks are an issue as well. It took me a few days to do research on what I should do for them and I took a chance on these collards after reading mostly positive reviews. 24 hours after putting these flea collars on them all fleas were gone.

The dogs demeanor and energy immediately improved and I am seriously very grateful that there are no more fleas on them/ Haven’t seen a tick on theme either.

I have not noticed ant negative effect so far. It’s been about 2 weeks, so far so good. it’s We will see how long they last and if they are effective after repeated uses. Will update. it’s been over a year and I am still very pleased. just bought another flea collar and it has been on for the past week or so.- still no problems.

it has worked for my dogs. I have a Chihuahua mix and a Bichon. They were being eaten alive, as well as myself, and I felt like I had tried everything. I didn't want to use any flea collar with chemicals because I had purchased everything that I could think of and nothing else worked.

I felt that using a natural flea collar would outweigh the risk of flea and tick borne disease. For me and my fur babies they have definitely worked.

Price was crazy low and I'm forever thankful for DEWEL PRO company.

Got this flea collar for my two dogs aka my children. Was extremely hard seeing them scratch away and bite their skin because some fleas wished to intrude. However, this flea collar for dogs has completely changed that, no itching and biting at their skin, and no flea in site.

I’m extremely happy, especially, since I was a bit skeptical that this collar would do nothing for my dogs and would be a total waste, but it wasn’t.

Also purchased their cat flea collar and am super pleased with that collar also!

This is the first flea and tick collar I have ever tried that actually delivered what was promised. I do not have a flea problem but for years the ticks have been horrible. After wearing your collar I few weeks I am finding no live ticks on my dogs. Simply the best flea collar for dogs.

I recommend this flea collar to everyone! We live out in the country where there are plenty of fleas and ticks around. My 3 dogs have been wearing their flea collars for about 5 months now, and none have had a single flea! I was skeptical in the beginning, but this really does work.

$20 for 8 months protection is literally a steal, I check my dogs often and have never seen a flea. If you are hesitant, buy it! You won’t be disappointed. I was very impressed.

Just moved from a no flea area to the coast, with many fleas. The seresto collar did not work at all. With in 2 hrs. Of putting the Dewel Pro flea collar on my dog completely quit scratching. Its 48 hrs. Later and she has yet to scratch. Oh happy dog! Dewel makes the best flea collars for dogs.

I normally take reviews with a HUGE grain of salt...I'm a skeptical so & so and think half the time they're PAID reviews. Having said that. Our dog Gizmo is OLD He'll be 16 in Feb. He was about 13 when we found this and were dealing with, what WE call, terminator fleas. You know the ones you can spray with NAPALM and they're like...whatever. We tried EVERYTHING.

Nothing was working and they were so bad on him he was losing weight.

I got online and just HAPPENED to get a banner ad for this flea collar and decided to check it out. Desperate we decided to buy it and I'm SO HAPPY WE DID!!

They've lasted around a year for us each time. The fleas were GONE within a few days. We'd get some popping back up from being outside or in the carpet (if you've got indoor animals you know the drill) and THEY were gone.

We did nothing else besides vacuum and from that day 2 years or so ago we've never looked back. He's old and has medical issues so capstar and the topicals would be really rough on him. ZERO issues with this. If you have dogs/cats and deal with flea issues you NEED to give this flea collar a try. You SAVE MONEY. C'mon..one collar for a YEAR vs MULTIPLE of the others? I can NOT recommend this enough!!!!

Ordered this flea collar about four days ago and NO FLEAS! I was picking fleas off of my little pup every day and now that the collar is on, NONE! Im so happy and I know my little pupper is too! We have four chickens, and live next to an empty field so fleas have been a major problem.

I have a 16 year old papillon/chihuahua mix. He was sick from topicals so I've been skeptical to use anything with chemicals. He has a history of skin problems as well, but his fur is fluffy enough right now that the collar doesn't rub too much on his skin. So far so good!

UPDATE: it's been a month since purchase and still not fleas! I literally see fleas jump on him while walking and they jump right off. This flea collar really works and I will continue to buy until proven otherwise :)
