Sentinel Flavor Tabs are chewable, beef-flavored tablets that kill flea eggs and larvae on dogs. They are also effective against heartworm, hookworm, roundworm and whipworm. Because these pills are given orally, they create no mess and pose little risk to humans. However, unlike topical treatments such as Frontline Plus for Dogs (Est. $65 for a 6-month supply), this medication won't kill adult fleas, and it isn't effective on ticks.

Sentinel Flavor Tabs are only available by prescription, as they can cause some side effects in dogs. Vomiting is the most common, but diarrhea, lethargy and appetite loss may also occur. Most owners find the pills easier to administer than topical treatments, but some complain that their dogs won't take the pills willingly. If you are looking for an oral medication that kills adult fleas, consider Capstar for Dogs and Cats (Est. $25 for 6 doses) or, for larger dogs, Capstar for Dogs. The medications are identical save for dosage, and either may be combined with Sentinel Flavor Tabs to wipe out fleas at all stages of their life cycle.

1. Main Street Pet Care

The website of this veterinary hospital goes into great depth about anti-flea treatments. The staff praises Sentinel Flavor Tabs as "the only flea control program that ALWAYS works" in dogs, but warns that this product takes a long time to wipe out an infestation because it has no effect on adult fleas.

2. VeterinaryPartner

Carol S. Foil writes that Sentinel Flavor Tablets are "a very easy way to break the life cycle," of fleas, but she warns that they take 4 to 7 months to eliminate them entirely. She recommends combining Sentinel Flavor tabs with another product to kill adult fleas during the first few weeks of use.

3. SimpleSteps.org

Sentinel Flavor Tabs earn a risk rating of one paw here, indicating low risk to pets and humans. However, the site, which concentrates on safety and environmental concerns, evaluates only one of the product's two active ingredients.
