SERGEANT'SGuardian Pro Flea & Tick Collar for Dogs, Kills Fleas & Ticks, Long Lasting Protection for 6 Months, Fresh Scent, One Size Fits All, 1 Collar

Love it

Upset I cannot return 2 boxes of sealed product or even receive a refund despite having it for less than 2 weeks. Does next to nothing for fleas and causes severe itching.Didn't realize until after I bought 2 more boxes after using what the original owner left for us to use.I encourage everyone to do a dive on this brand because it seems to be commonplace for the treatments to have inconsistent effectiveness and cause severe itching..

My pets went to the vet and came home with pets of their own… fleas! I then proceeded to try everything to get rid of them (The fleas, not the pets ), because we hadn’t had fleas around our house for decades.First, I tried the very expensive -once every two months- chews; they did nothing. Then I tried the topical treatments, spraying everything in the house with rosemary, washing, everything made of any kind of cloth, twice daily flea combings, and sprayed hard surfaces with vinegar. They all helped a little, but not enough.Finally, out of desperation, I tried the eight dollar flea collars; they totally worked.I waited two weeks to write this review because I was expecting that at any minute the collars would no longer be effective. They are still working like a charm.

I'm reluctant to criticize this product as others seem to have been pleased with it but it didn't work for my dog. On the positive side the shipping was very fast.

Gracias a este collar mi perrita en cuba no tiene garrapatas ni nada que la lastime y tiene un olor divino el collar

could work better on pets that dont go out much but noy ldeal if fleas are bad in the area or multiple pets in the house not the greatest for 3 large hairy saint benards living next to train tracks

nice purchase

Bought 3 for our dogs to get us by until we could get to vet. Did not work at all. We had our yard treated and gave flea bath before putting this on. Waste of money, didn’t do anything to prevent fleas. Our dogs are covered in them.
