  • Sentinel treats 5 common parasites and it cannot treat tapeworm infections. However, Sentinel Spectrum is a more improved version with having the ability to treat 6 parasites including tapeworm.
  • Sentinel is safe to use for your dogs from the young age of 4 weeks with weighing 2 lbs. While Sentinel Spectrum can be administered to your pet dogs as young as 6 weeks and 2 lbs in weight.
  • It is not difficult to find the generic version of Sentinel with similar ingredients a little bit cheaper, but the generic availability of Sentinel Spectrum is difficult.

Active ingredients in Sentinel Spectrum & how they work:

Sentinel Spectrum is a medication for dogs with three active ingredients:

  1. Milbemycin oxime
  2. Lufenuron
  3. Praziquantel

Milbemycin oxime is a strong heartworm disease preventative, parasiticide, and a dewormer, or anthelmintic. It is a proven heartworm preventative ingredient with trusted efficiency against common intestinal worms.

Lufenuron is an insecticide that is the only effective systemic, proven, and safe insect growth regulator (IGR). It distributes into the body fat of your pet dog as food for adult fleas that eat it and pass it on to their eggs. Lufenuron inhibits the development of chitin that makes the exoskeleton of larval fleas. During hatching, the inner organs of larval fleas get exposed to air and they die.

Praziquantel present in Sentinel Spectrum stops parasitic worm infections before they become a real danger for your pooch.
