Natural Flea and Tick Collar for Large Dogs - Provides 12-Month Protection, Offers Safe Pest Prevention, Waterproof and Durable - Includes Free Flea Comb and Tick Tweezer (27.5 in - 2 Packs)

The collars are durable and smell good. Makes your dog/cat smell lightly perfumed with lemongrass. Inside of some of the tins smelled pungent of ammonia? Was weird. But the collars were fine. No allergies, which I have to look out for specifically in my dog Dante. He doesn't take well to the synthetic chemical alternatives. The collars fit well, careful adjusting them for fit as I almost choked out one of my cats, I was surprised she was so patient as I readjusted the collar on her. I cut off the excess ends and tossed them around in the corners of my house for extra bug smackdown. It works. No fleas to be found on my animals. Dante would certainly let me know since he's sensitive to even just a few fleas munching on him and will chew himself to bits. Before, I had tried a bunch of homemade sprays and topicals. But those applications never really last long when you're dealing with an infestation. I had ran out of my diatomaceous earth and the order was taking its time to arrive, so that's when I bought these. I've got the DE all over my house for extra bug protection but these collars saved our skins. Hope Shengkou never stop selling these and they only continue to get bigger and improve upon their product, as the only other natural collar on here is twice the price.

I cannot say enough great things about this brand! Loyal customer for at least 6 years now from Mastiff/ Corso to hound dogs they fit perfectly every time. NOT A SINGLE FLEA in my home! 0 side effects on even my most sensitive pups! The smell is strong for a few days (lemon grass smell) then fades. No hair loss on any of my pups from these. I've told friends and family who were in a full blown flea infection of their area about these and within 24 hours they saw the difference on their homes.

I ordered this product for my 3 cats and dog. I appreciated that the collars are for both cats and dogs, making it more convenient and cost effective to be able to order 2 packs of 2 collars. The collars have a pleasant smell, are easy to fit and adjust to my pets different neck sizes. I have seen a reduction in scratching, especially in my cats. I would order this product again.

This is my second time buying these collars for my two smaller dogs. They worked to repel fleas and ticks so well last spring/summer season that I purchased again this year, only this time I bought the ones for large dogs and cut the excess off because the small dog collars were not in stock at the time. These are inside dogs but do spend time out in the backyard when their humans are out and I have not found a flea or tick on them the entire warm/hot season since using these collars. They work for many months and we live in the south where the warmer seasons start early and last longer. I like that they use natural essential oils instead of harsh chemicals as my Yorkie gets sick when the harsher chemical drops are used. The one problem I have encountered is trying to take the collar off for grooming as it is a little difficult to remove, at least in my experience, but the collars work so well, I can deal with that minor inconvenience. The Yorkie seems a little put off the first couple of hours after putting a new one on, probably because of the scent of the oils (not extremely strong nor unpleasant, she just doesn't like the new scent, I believe). It would probably help to leave it sit out a few hours before putting on the dog. The Beagle doesn't seem bothered at all, and in fact, the Yorkie gets over it pretty quickly as well. Overall, I highly recommend these collars if you are looking for a more natural flea/tick repellant.

I used to use a different flea and tick collar for my dog, and i couldnt find it anywhere, then i came across this one. What a major mistake I made by buying this garbage!!! My dog has never been bit by a tick in 10 1/2 years I've had her!!! Since I've used this collar, she has gotten bit by 2 ticks! I do not live in an area where ticks are everywhere by any means, but they always seem to find her. So, #1 this collar is a bunch of crap, it does not work. Some it may, and some people might also just to be lucky that their dog doesn't overly attract ticks or something, but some like my dog, it brought them to her. #2 about this junk of a collar, the design on a lot of these now are ridiculous to get on and off. It's unreal, it does not just glide in and out to close, the rubber material with the locking grips don't exactly go in like 1, 2, 3 and poof it's done. i couldn't even pull it all the way through, so i'd just lock it the best i could and once it fell off and then i put it back on. A nightmare. I only wanted a tick collar because i stopped using frontline and all that stuff when my dog was diagnosed with cancer over 2 years ago, i try to look for better alternatives. she is more holistic with everything i give her (she is now cancer free :-)) so, keeping her immune system good is very important... having to pull ticks off my dog from a collar that should work, and then not locking properly was huge stress. i would not recommend this product, the company that makes it i wouldnt buy anything from them, and i'm so annoyed, i wouldn't even buy now anything from the seller.
