Sentinel For Dogs

"Sentinel for Dogs will protect against heartworm disease and control adult hookworms, while removing and controlling roundworms and whipworms. The tablets will also help to protect against fleas. Active ingredients are Milbemycin Oxime and Lufenuron. The product is considered to be 100% effective. Veterinarian approval is needed to purchase this product."

SENTINEL contains the active ingredients milbemycin oxime and lufenuron and is well tolerated by all breeds. It is an oral tablet for the prevention and control of fleas, the prevention of heartworm (Dirofilaria immitis) disease and the treatment and control of roundworms (Toxocara canis, Toxascaris leonina), hookworms (Ancylostoma caninum) and whipworms (Trichuris vulpis) in dogs.

SENTINEL is given orally with a meal and should be given on the same day every month. It can be given with a small quantity of food before the rest of the meal is given, or per os immediately after feeding.

The active ingredient in Sentinel is Milbemycin oxime. It can be given at monthly intervals with a "reachback effect" of 2 months when doses are inadvertently delayed. This means if you forget a dosage for 2 months, your dog is still protected. If you've given your dog Sentinel for 12 straight months, this safety net extends to 3 months, with 97% effectiveness. If you forget for 4 months, this window shrinks to 4 months.

Sentinel Dogs Side Effects

Sentinel dogs side effects are rare. Some dogs may have side effects such as depression, hives, diarrhea, itching, vomiting, loss of appetite, lethargy and seizures. In dogs that already have worms, and among those dogs that have side effects, the most common one is diarrhea.
