Sentinel Flavor Tabs for Dogs 2-10 lbs

Sentinel Flavor Tabs for Dogs 2-10 lbs is a monthly oral medication formulated to prevent heartworm disease, control flea populations, and treat and control adult hookworms, roundworms, and whipworms in small dogs. This veterinarian-recommended broad-spectrum parasite protection combines the power of Milbemycin Oxime and Lufenuron, making it a trusted multi-parasitic preventive solution for dogs weighing between 2 and 10 lbs.

Unlike topical treatments that can be messy or washed off, Sentinel Tabs are administered orally with a palatable beef-flavored chewable tablet, offering convenience and reliable systemic protection. It breaks the flea life cycle by inhibiting flea egg development, ensuring comprehensive flea population control without killing adult fleas.

  • Intestinal Parasite Control: Effectively treats and controls adult hookworms, roundworms, and whipworms.
  • Palatable Chewable Form: Easy-to-administer beef-flavored tablets ensure better compliance.
  • Once-a-Month Dosing: Long-lasting and convenient protection with a single monthly dose.
  • Systemic and Non-Messy: Works from the inside, avoiding messy topical applications.

What Ingredients Are in Sentinel Flavor Tabs for Small Dogs?

Active Ingredient

Purpose

Milbemycin Oxime (2.3 mg)

Prevents heartworm disease & treats intestinal worms

Lufenuron (46 mg)

Inhibits development of flea eggs

Milbemycin Oxime: A macrocyclic lactone antibiotic that targets the nervous system of parasites, paralyzing and killing them.

Lufenuron: An insect development inhibitor that disrupts the formation of chitin in flea larvae and eggs, effectively halting flea reproduction.

Are There Any Side Effects of Sentinel Flavor Tabs?

Most dogs tolerate Sentinel Tabs well. However, some potential side effects may include:

  • Vomiting
  • Diarrhea
  • Lethargy
  • Ataxia (loss of coordination)
  • Pruritus (itchiness)

If you notice any adverse reactions, especially signs of allergic response like facial swelling or difficulty breathing, contact your veterinarian immediately.

What Precautions or Warnings Should You Know About Sentinel for Small Dogs?

  • Heartworm Testing: Dogs should be tested for existing heartworm infections before starting treatment.
  • Not for Use in Cats: Sentinel Tabs are formulated exclusively for canine use.
  • Puppy Safety: Safe for use in puppies 4 weeks of age or older, and weighing 2 lbs or more.
  • Pregnancy & Breeding: Consult your vet if your dog is pregnant or lactating.

How Does Sentinel Compare to Competitor Products?

Compared to products like Heartgard Plus or NexGard Spectra, Sentinel:

  • Does not kill adult fleas, but breaks their life cycle — ideal for homes focusing on flea prevention, not immediate flea kill.
  • Covers whipworms, which some competitors like Heartgard do not.
  • Oral and mess-free, unlike topical preventives such as Advantage Multi.
  • Beef-flavored chewable, encouraging better compliance in small picky dogs.
