Step-by-step application:

  3. Part your dog’s fur at the base of the neck between shoulder blades.
  4. Place applicator tip on exposed skin and squeeze 3–4 times in one spot.
  5. Keep applicator compressed while removing it to avoid drawing fluid back in.
  6. Do not massage the solution or apply to wet/damaged skin.
  7. Wash hands after application.

A veterinarian or vet tech should demonstrate proper application before first use.

When Should You Start Selarid Treatment?

  • Begin monthly applications as early as 6 weeks of age for puppies.
  • Start before mosquito season to effectively prevent heartworms.
  • Continue treatment year-round, even in colder climates, to maintain uninterrupted protection from fleas and mites.

Bathing & Grooming Tips After Applying Selarid

  • Wait at least 2 hours before bathing your dog after applying Selarid.
  • Use mild, vet-approved shampoos that won’t strip the skin of Selamectin.
  • Avoid grooming tools on the application site until fully dry (about 4–6 hours).

What Ingredients Are in Selarid for Dogs?

Active Ingredient

Purpose

Selamectin (60 mg)

Systemic antiparasitic; neurotoxic to parasites

Selamectin is a macrocyclic lactone that interrupts neurotransmission in parasites, causing paralysis and death. It is absorbed transdermally and circulates throughout your dog’s system, offering inside-out protection.

How Does Selamectin Work in Selarid?

Selamectin, the active ingredient in Selarid, is a macrocyclic lactone that targets the nervous system of parasites. It works by increasing the permeability of cell membranes to chloride ions in invertebrates, leading to paralysis and death of parasites such as fleas, ticks, and heartworms.

Because Selamectin is absorbed through the skin and circulates in the bloodstream, it offers systemic protection, unlike some topical-only flea treatments.

Tips for First-Time Users

  • Ask your vet or vet tech to demonstrate the first application.
  • Apply in a calm environment—use treats or praise to distract nervous pets.
  • Mark a monthly reminder on your calendar or use a mobile app to stay consistent.
  • If your pet gets wet within 2 hours of application, consult your vet about reapplying.

Can I Switch from Revolution to Selarid?

Yes! Since Selarid contains the exact same concentration of Selamectin as Revolution, transitioning is generally seamless. However:

  • Begin Selarid after the last Revolution dose period ends
  • Maintain monthly consistency
  • Consult your vet before switching if your pet has had sensitivity to any topical treatments

Are There Any Side Effects of Selarid?

Most dogs tolerate Selarid well. However, side effects may occur, including:

  • Localized hair loss or irritation at application site
  • Vomiting or diarrhea (with or without blood)
  • Lethargy, reduced appetite, or excessive salivation
  • Rare: ataxia (uncoordinated movements), muscle tremors, seizures
  • Temporary stiff or discolored hair, or powdery residue

If you notice any unusual symptoms, contact your veterinarian immediately.

What Precautions and Warnings Should I Know?

  • Do not apply to broken or wet skin – Selarid contains alcohol and may irritate.
  • Keep out of reach of children and pets until the application site is dry.
  • Not for use in cats or other animals unless properly dosed.
  • Avoid contact with your fingers during application.
  • Do not administer orally or massage into skin.

How Should Selarid Be Stored?

  • Store below 86°F (30°C)
  • Keep in original packaging until use
  • Protect from light and moisture
