Flea Collar for Dogs, 8 Month Flea and Tick Prevention, 27 inch Adjustable, 2 Count

Had bought another brand just a couple of months ago and had bought this same brand last year. This time they did not work to prevent fleas. I ordered the Advanllent Flea Collar for all of my three wiener dogs to replace the other brand. After bathing and giving capstar pills to knock the fleas down we put on the Advanllent Flea Collars and have not seen a flea since. Here we are just about a month in and no flea scratching and no bites on us. If the Advanllent Flea Collar keeps the fleas off it will be our go to brand from now on.

First time using these. Had it on my dog for about 2 months and no issues! Great option.

UPDATE: I received a long, considerate explanation from the company stating that these collars indeed do NOT contain Deltamethrin but only the essential oils as stated. They said the 6/8-month discrepancy was due to a typo and they will fix that. They said this particular product does not require submission to the EPA because the EPA controls pesticides and this doesn't have any. That does not explain why EPA Est. No. 93801-CHN-1 was listed on the product container, the same number that routed me to the info I mentioned below. But I will now put the collars on my dogs (on the first day of the month, February, so I'll remember when I put them on) and test how they react to them. I will post more after they've worn these collars for a while. I'm especially interested in how my honeybees are going to react to them.INITIAL REVIEW: When I got a chance to review this 8-month dog flea and tick collar for Vine, I decided to go on and order two more from the same product page because I have three dogs and they are due for a collar change now. They all arrived the same day, the Vine one and the two I ordered separately. The containers are exactly the same. They look exactly the same. But the two I ordered say 6 months protection, not 8 months.As with any item I receive that has discrepancies like this, I started looking more closely at the fine print. The first thing I noticed is that there is no detailed list of ingredients. All say “Compound Essential Oil 4%, Other inredients 96%.” Each one has the exact same bar code and the same “manufactured for” date (New Thinking Technology, Inc., out of Brighton, Colorado). So I went online to search for the only other information that might provide a clue as to what’s actually in these collars: EPA Est. No. 93801-CHN-1 ACTIVE INGREDIENT.What pops up is an application for a flea and tick collar formulation containing the pesticide Deltamethrin with conditional approval on 5/3/21. There is a note that the product must be rebranded to contain the Est. No. 93207-2 or it cannot be sold. At the end of this application, under “ABNS,” a number of flea and tick collars are listed:Jmxu’s Flea and Tick collar for dogsJmxu’s Proguard plus flea and tick collar for dogsKingMo Flea and Tick collar for dogsAdvanllent Flea and tick collar for dogsSOBAKEN Flea and Tick collar for dogsJiamin Xu of New Thinking Technology, Inc., is the name on the EPA application; this is the company listed on all three flea collar packages I received.I have contacted the EPA to try to find out what "ABNS" means; does it mean that all the collars listed have this same formulation? I have a fish pond, and Deltamethrin is supposedly highly toxic to fish and also to honeybees, so does are my dogs running around outside in these collars a threat to them? It doesn't say. (It DOES say lemongrass oil is used in these collars on the product description page, and lemongrass oil is highly attractive to bees because it smells like the queen. Beekeepers use it to attract swarms to nest in new hive boxes.)As soon as I find out more from the EPA, I will come back and post what I learn. It may be that this particular collar is just fine, which is why for now I'm giving it three stars, but it makes me nervous that the packaging had the 6/8-month discrepancy and that no actual ingredients are specified anywhere. This looks like a Chinese product being sold from a U.S. address; I know there have been issues in the past with China-sourced pet products being harmful to our pets, so I’m exercising a high degree of caution and not putting these collars on my dogs until I know more.

The media could not be loaded. This is my very first Amazon review. I feel a responsibility to warn others of the potential harm you will expose your pet to if you use this product.DO NOT USE THIS PRODUCT.You think you're saving money... you think it's safe. It states it is a "natural" product.This flea and tick collar almost took my best friend's life! And to mention left me with a $2000 vet bill!I put the collar on her. She was fine for the first few weeks but I noticed she started avoiding her food. Last week, she abruptly stopped eating. I took her to the vet. They did xrays. Nothing. They did ultrasounds. Nothing. They did bloodwork. She was severely anemic. They ran tests for parasites. Nothing. She was so anemic they ran the test again. They thought she was bleeding out in her stomach. She wasn't! She was being poisoned by this collar! They prepared me for the worst and gave me all the emergency vet numbers. I had to take her in every day for bloodwork and her numbers were decreasing.I had changed NOTHING in my dog's routine or food or even her treats except for this collar! She was panting excessively. She wouldn't eat for 5 days. She was so lethargic and weak I thought she was leaving me.I took her back in for bloodwork and a few days after removing the collar, sure enough her numbers increased slightly! We waited the weekend holding off on high levels of steriod and antibiotic medication to see how she responds since removing the collar. We just got back from the vet today and she is within normal range and no longer anemic 5 days after removing the collar!! Unbelievable! If I could sue, I would! This has been so distressing after losing my husband to cancer, I thought I was losing my best friend!I repeat. DO NOT USE THIS PRODUCT!

Used this product last Summer on our Shiba Inu and it worked as described so we purchased again for this years tick season.

No issues on female dog, our male not so good, was acting really strange after a few days, took off, back to normal in a day

I got this for my puppy last year because I needed a flea and tick collar that wouldn't break the bank. There was no irritation unlike with a certain name brand collar I later tried after this one expired. I did not see a single flea or tick on my dog through the entire summer. I was truly blown away. I expected to see some here and there since this wasn't name brand, but there was NOTHING! A happy dog is a happy dog mom.

Es un producto muy bueno y efectivo.
