Rx Sentinel Spectrum Chews 2-8lbs x 1 tablet

Sentinel Spectrum Chews For optimal parasite protection, Sentinel Spectrum Chews are formulated with three active ingredients that control and prevent fleas, heartworm and intestinal worms in dogs. These three active ingredients include Milbemycin oxime, praziquantel and lufenuron. Milbemycine oxime prevents nerve transmission in invertebrates, which protects against heartworm, round worm, hookworm and whipworm. Praziquantel inflicts a muscle spasm in tapeworm, which is then attacked by enzymes and then disintegrated. Lufenuron regulates insect growth and disrupts the flea breeding cycle. Adult fleas that feed on an animal that has taken Sentinel Spectrum Chews will produce eggs or larvae that do not make it to the adult stage, thus reducing the number of fleas. A monthly, beef-flavored chew is an easy way to keep your pet healthy and parasite-free while also giving your pup a delicious reward. All prescription items are NON-REFUNDABLE and NON-RETURNABLE.

Sentinel Spectrum 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 Chews, 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 Chews. - DIRECTIONS:Directions Once a month, ideally on the same date. If a dose is overdue by >15 days, treat immediately and resume monthly dosing. If a dose is missed by 15-30 days, heartworm prevention can be maintained if treated immediately and monthly dosing resumes at least the next 2 months. If a dose is missed by >60 days, a veterinarian must be consulted in case the animal has contracted heartworm. Dosing may be recommenced, and a blood test for adult heartworm must be performed after 6 months. Dose must be given with a full meal, either within food or immediately afterwars (to allow effective absorption of lufenuron).
