NexGard for Dogs
Brand: Boehringer Ingelheim
NexGard is an FDA-approved, prescription-only oral soft chew designed to rapidly kill adult fleas and treat and control tick infestations in dogs.
This product is intended for dogs.
Overview
NexGard (afoxolaner) is a highly effective, beef-flavored soft chewable tablet that provides comprehensive protection for dogs against external parasites. Unlike topical treatments such as Frontline Plus, which sit on the skin, NexGard is ingested and absorbed into the bloodstream. Once in the system, the active ingredient afoxolaner works by overstimulating the nervous system of fleas and ticks, leading to their rapid elimination. It is specifically formulated for canine use, providing a reliable defense against common infestations that can plague pets throughout the year. Many veterinarians recommend this as a primary defense, often comparing its efficacy to long-lasting alternatives like the Seresto Collar, though NexGard offers the convenience of a monthly oral administration rather than a collar. If you are also treating a sudden, severe flea outbreak, your veterinarian might suggest a fast-acting supplement like Capstar in conjunction with your regular monthly dose. It is essential to understand that while topical products might provide some contact-kill action, oral systemic treatments like NexGard ensure that the parasite must bite the dog to be affected, which is highly efficient for ending the parasite life cycle. Furthermore, for households with mixed-species pets, it is crucial to note that NexGard is exclusively for dogs; feline-specific parasites should be managed with products like Revolution Plus or other appropriate feline alternatives. Proper parasite prevention is a cornerstone of veterinary wellness, as fleas and ticks are not just a nuisance but can transmit serious vector-borne diseases. By utilizing a systemic medication, you ensure that your dog remains protected regardless of grooming habits, swimming, or bathing, which can sometimes reduce the effectiveness of topical applications.
What It's For
- Flea Infestations: Treats and prevents adult flea infestations for a full month by killing them before they can lay eggs.
- Tick Control: Kills black-legged ticks, American dog ticks, brown dog ticks, and lone star ticks to reduce the risk of transmitted diseases.
- Prevention of Flea Allergy Dermatitis: Eliminates existing fleas to soothe skin irritation and prevent the severe allergic reactions caused by flea saliva.
- General Parasite Management: Acts as a consistent, year-round prophylactic against common external parasites found in diverse environments.
How To Use
NexGard should be administered once a month orally. Because the chew is formulated with a beef flavoring, most dogs will readily consume it as a treat. It can be given with or without food, though offering it at a consistent time each month helps ensure compliance and steady protection. If your dog is a picky eater, you may hide the chew inside a small amount of food or a treat to ensure the entire dose is ingested. Ensure that the entire dose is consumed by the dog. If you suspect that a portion of the chew was spat out or not swallowed, you may need to provide a replacement dose. Consult your veterinarian for guidance if you miss a dose or if the dog vomits shortly after administration. Always weigh your dog accurately before purchasing, as NexGard is weight-specific to ensure the correct dosage of afoxolaner is delivered safely to your pet.
Precautions
NexGard is intended for use in dogs only and should never be administered to cats or other animal species. Use with caution in dogs with a history of seizures or other neurological conditions, as the active ingredient belongs to the isoxazoline class, which has been associated with adverse neurological signs in rare instances. Always inform your veterinarian of your dog’s full medical history before starting any new parasite prevention regimen. Common side effects may include vomiting, dry skin, lethargy, diarrhea, or anorexia, though these are generally mild and transient. If these symptoms persist or become severe, contact your veterinarian immediately. Keep this product out of reach of children and other pets, and store at room temperature to maintain the integrity of the medication.
