What is Sentinel Spectrum?

Sentinel Spectrum is an oral treatment for dogs that offers broad-spectrum protection against multiple parasites. It comes in the form of a beef and bacon-flavoured chew that controls the flea population by killing flea eggs and flea larvae. The treatment also kills immature heartworm larvae, thus preventing heartworm disease in dogs.

It is a monthly treatment that controls various gastrointestinal worms including hookworms, tapeworms, roundworms and whipworms. It is indicated for use in puppies and dogs from 6 weeks of age.

What are the active ingredients in Sentinel Spectrum? How do they work?

Sentinel Spectrum contains milbemycin, praziquantel and lufenuron. Milbemycin and praziquantel act on the parasites’ nervous system, leading to their paralysis and death. Lufenuron hinders the development of flea eggs and larvae by interfering with parasites’ nervous system.
