Sergeant'sGuardian Pro Flea & Tick Collar for Dogs, 1 Count

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

Our yorkipoo had a very old case of fleas. After using topical solution from the vet, fleas remained. We bought this collar, and 2 weeks later fleas still persist and getting worse. This collar did nothing.

My pets went to the vet and came home with pets and 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 collar; 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.

nice purchase
