SENTINEL Spectrum protects against six of the common internal and external parasites that threaten your dog. Just one convenient oral dose will protect your pet against heartworm and fleas, as well as roundworm, hookworm, whipworm and tapeworm.


Once a month, ideally on the same date.


Each chew contains 23mg milbemycin oxime,
460mg lufenuron and
228mg praziquantel


Sentinel Spectrum Tasty Chews can be safely used in puppies from 6 weeks of age, breeding males and females, and collies sensitive to ivermectin.

Sentinel Spectrum Tasty Chews have been safety tested at up to 10 times the recommended dose.

If an animal with adult heartworm infection (and therefore circulating microfilariae)is given Sentinel Spectrum, a transient shock-like reaction can occur.

To avoid this, dogs should be tested for adult heartworm and treated if necessary, before starting Sentinel Spectrum.
