These monthly chewables are potent against fleas and also help prevent heartworm disease. Formulated with milbemycin oxime and spinosad, they fight multiple parasites and reduce infestations. The beef-flavored tablets make administration easy and enjoyable for dogs.
The complex formula may lead to side effects, so they are recommended for dogs over 8 weeks old weighing 5 pounds or more.
Sentinel Flavor Tabs
