Protecting pets from parasites is an essential part of responsible pet care. Revolution for dogs and cats is a veterinarian-prescribed monthly topical treatment designed to help safeguard pets from a wide range of harmful parasites. With a single application each month, pet owners can help reduce the risk of flea infestations, heartworm disease, ear mites, and other parasite-related health problems that may affect both dogs and cats.
For more than 25 years, veterinarians have relied on Revolution (selamectin) as part of comprehensive parasite prevention programs. Understanding how it works, what it protects against, and why parasite prevention matters can help pet owners make informed decisions about their pets’ health.
What Is Revolution?
Revolution is a monthly topical medication containing selamectin, a parasite control ingredient that is absorbed through the skin and distributed throughout the body. Once applied at the base of the neck in front of the shoulder blades, the medication helps protect pets against several common internal and external parasites.
Unlike oral medications, Revolution is administered directly onto the skin. The quick-drying formula requires only one application per month and does not require gloves during application. Pet owners can typically resume normal interaction with their pets after applying the product, provided they wash their hands afterward.
Parasites Covered by Revolution
The protection offered by Revolution differs slightly between dogs and cats.
For Dogs
Revolution helps protect dogs against:
- Fleas
- Heartworm disease
- Ear mites
- Sarcoptic mites (canine scabies)
- Certain tick species, including the American Dog Tick
Dogs can begin treatment at 6 weeks of age or older, according to product safety guidelines.
For Cats
Revolution helps protect cats against:
- Fleas
- Heartworm disease
- Ear mites
- Roundworms
- Hookworms
Cats can begin treatment at 8 weeks of age or older.
Why Flea Prevention Matters
Fleas are among the most common parasites affecting dogs and cats. Even indoor pets are not completely protected because fleas can enter homes through:
- Other pets
- Wildlife
- Shoes and clothing
- Open doors and windows
Flea infestations can cause:
- Persistent itching
- Skin irritation
- Allergic reactions
- Hair loss from excessive scratching
In cats, flea control may also help reduce the risk of tapeworm transmission because fleas can serve as intermediate hosts for tapeworms.
Signs of Flea Problems
Watch for:
- Excessive scratching
- Hair loss
- Red or irritated skin
- Flea dirt in the coat
- Visible fleas
Consistent monthly prevention is often more effective than treating infestations after they occur.
Understanding Tick Risks in Dogs
Ticks can be found throughout the year in many regions and may attach to dogs during walks, outdoor play, or contact with grassy areas.
Ticks are concerning because they can:
- Cause skin irritation
- Trigger allergic reactions
- Be difficult to detect beneath thick fur
- Attach inside the ears or other hidden areas
Even diligent inspection may not identify every tick, making preventive treatment an important component of canine health care.
Ear Mites: Small Parasites, Big Discomfort
Ear mites are highly contagious parasites that spread through direct contact between animals.
Common Symptoms of Ear Mites
Pets affected by ear mites may develop:
- Red, itchy ears
- Dark brown or black ear discharge
- Ear inflammation
- Pain or discomfort
- Ear damage caused by excessive scratching
Because ear mites can easily spread among pets living in the same household, prompt treatment and prevention are important.
Heartworm Disease: A Serious Threat
Heartworm disease is one of the most dangerous parasitic conditions affecting dogs and cats.
Transmission occurs through the bite of an infected mosquito. In some cases, a single mosquito bite may be enough to infect a pet.
Potential Consequences of Untreated Heartworm Disease
If left untreated, heartworm infection may lead to:
- Lung damage
- Breathing difficulties
- Reduced exercise tolerance
- Damage to organs such as the liver and kidneys
- Heart failure in severe cases
Because treatment can be complicated and costly, veterinarians generally recommend year-round prevention rather than waiting for infection to occur.
Sarcoptic Mange in Dogs
Sarcoptic mites can cause a skin condition known as sarcoptic mange, often referred to as canine scabies.
Symptoms of Sarcoptic Mange
Affected dogs may experience:
- Intense itching
- Frequent scratching and biting
- Red or inflamed skin
- Crusty scabs
- Skin scaling
- Hair loss
The condition is highly contagious and can spread rapidly between animals if not addressed.
Roundworms in Cats
Roundworms are common intestinal parasites that can infect cats through contaminated soil, infected prey, or environmental exposure.
Signs of Roundworm Infection
Heavy roundworm infestations may cause:
- Vomiting
- Weight loss
- Poor coat condition
- Potbellied appearance
- Digestive disturbances
Kittens are particularly vulnerable and should receive appropriate veterinary care and parasite prevention.
Hookworms in Cats
Hookworms are another intestinal parasite that can affect feline health.
Health Risks Associated With Hookworms
Hookworm infections may result in:
- Anemia
- Weight loss
- Diarrhea
- Weakness
Severe infections can become life-threatening, especially in young kittens or immunocompromised animals.
How Revolution Works
After application, Revolution is absorbed through the skin into the bloodstream. The medication circulates throughout the body, helping prevent heartworm disease while also redistributing to the skin to provide protection against external parasites.
This dual-action mechanism allows one monthly treatment to address multiple parasite threats simultaneously.
Benefits of Monthly Topical Protection
Many pet owners appreciate Revolution because it offers:
- Once-monthly dosing
- No pills to administer
- Quick-drying application
- Broad parasite coverage
- Convenient routine protection
Maintaining a consistent monthly schedule is important because missed doses may reduce effectiveness.
What If You Miss a Dose?
If a monthly dose is missed:
- Apply the missed dose as soon as possible.
- Resume the regular monthly schedule.
- Do not administer a double dose unless specifically directed by your veterinarian.
Setting reminders through calendars, mobile apps, or email notifications can help ensure continuous protection.
Safety Information and Considerations
Before using Revolution, discuss your pet’s medical history with your veterinarian. Inform them of:
- Previous allergic reactions to medications
- Existing medical conditions
- Current medications or treatments
Some pets may experience mild side effects, including:
- Temporary hair loss at the application site
- Mild skin irritation
- Redness or flaking
- Occasional gastrointestinal upset
Any unusual or severe reaction should be reported to a veterinarian promptly.
