NexGard vs. Bravecto: Which Flea and Tick Preventive Is Safer for Your Dog?
When it comes to protecting your dog from fleas and ticks, two of the most popular prescription oral medications are NexGard and Bravecto. Choosing between these two can be challenging for pet owners, especially when prioritizing safety as a primary concern. Both products have been extensively tested for safety and efficacy, but there are some differences that may influence which is more suitable for your pet.
Why Flea and Tick Prevention Matters
Fleas and ticks are not only a source of discomfort for dogs, but also a serious health risk. They can transmit dangerous diseases such as Lyme disease, Rocky Mountain spotted fever, and ehrlichiosis. Because these parasites are active year-round in many parts of the United States, consistent and effective prevention is essential.
Overview of NexGard
NexGard is a monthly oral chewable tablet that targets both fleas and ticks. It starts working quickly and is known for its palatability, making it easier to administer to most dogs.
- Active Ingredient: Afoxolaner
- Protection Duration: 30 days
- Additional Coverage: NexGard Plus also treats heartworms and some intestinal parasites
- Prescription Requirement: Yes
Overview of Bravecto
Bravecto offers long-lasting protection and is available in both chewable and topical forms. One dose typically provides up to twelve weeks of protection against fleas and multiple species of ticks.
- Active Ingredient: Fluralaner
- Protection Duration: Up to 12 weeks
- Prescription Requirement: Yes
Safety Comparison
Both medications have passed rigorous clinical trials and are FDA-approved. However, specific considerations may make one preferable over the other for certain dogs.
- Seizure History: Dogs with a history of neurological disorders may tolerate Bravecto better, although both NexGard and Bravecto carry cautionary notes about use in dogs with seizures.
- Age and Weight Restrictions: Each medication has minimum age and weight recommendations, so always consult with your vet.
- Side Effects: The most commonly reported side effects for both include vomiting, diarrhea, lethargy, and decreased appetite. Side effect profiles are largely similar.
Veterinarian Recommendations
Veterinarians often consider both NexGard and Bravecto to be highly effective and safe when used appropriately. The choice often comes down to the pet owner’s preference for dosing frequency and the specific health needs of the dog.
- NexGard: Better for owners who prefer monthly dosing for ease of tracking and routine
- Bravecto: Ideal for those seeking less frequent administration (every 12 weeks)
Other Treatment Options to Consider
While both NexGard and Bravecto are leading options, other treatments are available:
- Simparica Trio: Monthly protection against fleas, ticks, heartworms, and intestinal worms
- Comfortis: Monthly chew known to be well-tolerated by dogs with food sensitivities
- Collars, topicals, and sprays: Provide varying levels of protection and frequency but require more frequent reapplication
Factors to Discuss with Your Vet
- Dog’s age, weight, and breed
- Pre-existing medical conditions
- History of medication side effects
- Lifestyle and exposure risk (e.g., hiking, daycare, urban or rural living)
- Ease of medication administration (pills vs. topical)
Final Thoughts
There is no one-size-fits-all answer to choosing between NexGard and Bravecto. Both are highly safe and effective when used correctly. The best decision is made in collaboration with your veterinarian, who can take into account your dog’s unique health profile and risk factors. Regardless of the product chosen, maintaining consistent and year-round flea and tick control is key to safeguarding your pet’s health.
