Ultimate Guide to Sentinel Spectrum Chewables for Dogs

Meet the Six-in-One Parasite Preventer: Sentinel Spectrum Chewables for Dogs!

Sentinel Spectrum Chewables for Dogs is a prescribed monthly beef-flavored chewable that protects your dogs by preventing, controlling, and killing six dangerous parasites - heartworms, whipworms, hookworms, roundworms, tapeworm, and fleas. Sentinel Spectrum ensures that your pup is in their healthiest condition.

How does Sentinel Spectrum work?

Sentinel Spectrum for Dogs is a medication with three active ingredients - Milbemycin Oxime, Lufenuron, and Praziquantel.

Milbemycin Oxime is a powerful parasiticide and an anthelmintic (i.e., dewormer). It is 100% effective heartworm disease preventative, and also controls three dangerous gastrointestinal worms (i.e., adult roundworms, hookworms, and whipworms) by acting on their nervous system.

Lufenuron is an insecticide and insect growth regulator (IGR). As flea birth control, Lufenuron disrupts the flea cycle both by preventing larvae from reaching adulthood and inhibiting growth within eggs. The development of protein chitin that builds a larval's exoskeleton causes larvae to die once inner organs are exposed to air after hatching.

And finally, the third active ingredient Praziquantel is an anthelmintic that expels anti-parasitic worms like trematodes (e.g, tapeworms) by causing muscular spasms that ultimately kill the parasitic worms. Praziquantel is also an Insect Growth Regulator (IGR) that inhibits newly hatched insect larvae from reaching adulthood or reproducing.

How is Sentinel Spectrum for Dogs administered?

Sentinel Spectrum for Dogs is an oral, once-monthly treatment and protects your dog for the next 30 days. These beef-flavored Sentinel Spectrum's directions are that the chews are to be split into chewable pieces and hidden in food. Make sure that your dog consumes the entire chewable, especially for adequate absorption of Lufenuron.

Sentinel Spectrum chews are used year-round for maximum prevention effectiveness.

Sentinel Spectrum's doses are based on your dog's body weight which then determines the milligram (mg) amount of each active ingredient per month. See the Sentinel Spectrum dosage chart below:

Dog's Body Weight Milbemycin Oxime (mg) Lufenuron (mg) Praziquantel (mg)
Sentinel Spectrum 2 - 8 lbs. (Orange) 2.3 46 22.8
Sentinel Spectrum 8.1 - 25 lbs. (Green) 5.75 115 57
Sentinel Spectrum 25.1 - 50 lbs. (Yellow) 11.5 230 114
Sentinel Spectrum 50.1 - 100 lbs. (Blue) 23 460 228

All Sentinel Spectrum boxes are available in 6 (month) packs and 12 (month) packs.

What dogs should not be treated with Sentinel Spectrum?

Dogs that shouldn't take Sentinel Spectrum are those that are below 6 weeks old or weigh less than 2 pounds; those that take other medication that will have a negative interaction; and those that are already taking an alternate heartworm medication. Breeding, pregnant, and lactating females have not been evaluated.

What is the Sentinel Spectrum for Dogs' side effects of which you should be aware?

Test for heartworm disease before deworming therapy or before using Sentinel Spectrum for Dogs.

Sentinel Spectrum's common negative reactions reported are vomiting, diarrhea, incoordination, lethargy, decreased appetite, itching, hives, convulsions, hypersalivation, and labored breathing. Contact your veterinarian if any of the above or other effects occur after ingesting the Sentinel Spectrum chews.
