Spectra Shield™ Collar Attached Medallion

Manufacturer : Durvet Animal Health Care

Spectra Shield Collar Attached Medallion contains Zetacypermethrin which is a powerful synergized pyrethroid that kills adult fleas and all blood-feeding stages of ticks. The second ingredient is Piperonyl Butoxide which is a mixed-function oxidase inhibitor that ensures maximum effectiveness of Spectra Shield. While this highly effective combination protects pets, it exhibits very low toxicity to animals and humans.

When hung on the dog’s collar the active ingredients migrate to the surface of the tag and are then transferred from the surface of the tag to the hair of the dog where the actives mix with the natural oils on the skin and hair and migrate all over the body. This process is facilitated by the natural oils on the hair and skin of the animal.
