PetArmor Plus for Dogs
Brand: Sentry
PetArmor Plus for dogs is a fast-acting, long-lasting, waterproof topical treatment that kills adult fleas, ticks, and chewing lice while breaking the flea life cycle to prevent future infestations.
This product is intended for dogs.
Overview
PetArmor Plus is a veterinary-grade, over-the-counter topical treatment specifically formulated for the needs of dogs, providing protection against a variety of external parasites. By leveraging a dual-action formula containing fipronil and s-methoprene, this product works to eliminate mature parasites on contact while simultaneously inhibiting the development of flea eggs and larvae. For owners who frequently manage flea allergy dermatitis, this product serves as a foundational defense to stop the biting cycle before it results in severe skin lesions or secondary bacterial infections. Its targeted application directly to the skin ensures that the medication is distributed through the sebaceous glands, providing full-body protection that lasts for thirty days.
While many owners may consider alternative solutions like Capstar Fast-Acting Tablets for immediate knockdown of live fleas, PetArmor Plus is intended for long-term, monthly maintenance. It is often compared to professional-grade treatments like Parastar Plus due to its similar active ingredients and effective mode of action. When an environment is heavily contaminated with dormant eggs or pupae, pet parents might supplement this topical treatment with Knockout Area Treatment Spray to reduce the parasite load within the living quarters of the home. This comprehensive approach is essential for preventing the cyclical re-infestation that often plagues multi-pet households.
Unlike oral medications or products like the Ruff Maxx Flea & Tick Collar, PetArmor Plus remains effective even if the dog goes for a swim or receives a bath, provided the product has had time to absorb. However, it is always recommended to avoid harsh shampoos for 24-48 hours post-application. If your dog also requires protection against mosquitoes or sand flies, you might consider Vectra 3D, which offers a slightly broader spectrum of repellency. Understanding the specific risk factors in your region is the best way to determine if PetArmor Plus is the right choice for your canine companion's seasonal health regimen.
What It's For
- Flea Control: Kills adult fleas and prevents the development of flea eggs and larvae.
- Tick Prevention: Eliminates brown dog ticks, American dog ticks, lone star ticks, and deer ticks to reduce the risk of transmitted diseases.
- Chewing Lice Treatment: Rapidly kills chewing lice to provide relief from irritation and scratching.
- Cycle Breaking: Inhibits the flea life cycle at the egg and larvae stages, preventing new generations from maturing.
How To Use
To apply PetArmor Plus, ensure your dog is dry and remove one applicator from the package. Hold the applicator upright, pointing away from your face, and snap the tip off at the pre-scored line. Part your dog's hair between the shoulder blades until the skin is clearly visible, and place the tip of the applicator directly against the skin. Squeeze the entire contents of the tube firmly in one single spot, ensuring the liquid is not applied to the hair coat. Allow the area to dry completely before touching or letting other pets near the application site. It is important to apply the product monthly to maintain consistent protection. If you reside in an area where flea season is year-round, you must adhere to a strict 30-day schedule to prevent the population from rebounding. For households with multiple dogs, ensure that each pet receives the dosage specifically designed for their weight class and keep them separated until the product is fully absorbed to prevent grooming, which could cause temporary salivation if ingested.
Precautions
PetArmor Plus is exclusively for use on dogs and should never be used on cats or other species, as cats are particularly sensitive to fipronil. Keep the product stored in a cool, dry place inaccessible to children and pets. Avoid contact with the eyes and skin during application, and wash your hands thoroughly after use. If the dog shows signs of irritation, such as redness or excessive itching at the application site, bathe the dog with mild soap and consult your veterinarian immediately. Do not use on puppies under 8 weeks of age or weighing less than 4 lbs without veterinary guidance.
