BRAVECTO Topical for small to medium dogs provides fast-acting protection against fleas and ticks. The product claims up to 12 weeks of protection with a single application, offering convenience for owners who prefer a non-daily treatment. The long duration helps reduce the frequency of reapplication and can improve adherence for busy households. Application is topical, making storage straightforward and dosing weight-dependent.

The chew format can be preferred by pets and owners who dislike topical applications. Like the topical, it is designed to be fast-acting and long-lasting, reducing the need for frequent dosing rather than relying on monthly schedules. Always ensure the dog’s weight matches the chew’s labeled range for effectiveness.
BRAVECTO Topical Solution for Cats, 6.2–13.8 Lbs

This BRAVECTO option extends flea and tick protection to feline companions. With a 12-week protection window, it provides a longer interval between doses compared to monthly products.

The product emphasizes rapid onset and long-lasting coverage that minimizes re-dosing frequency.
BRAVECTO Topical Solution for Dogs, 44–88 Lbs

This larger-weight topical option covers bigger dogs with up to 12 weeks of flea and tick protection from a single dose. The topical application can be preferred for pets that dislike pills or chews. Ensure the dog’s weight matches the indicated range for optimal protection and safety. The long-acting formulation reduces the need for frequent dosing in routine pet care.
BRAVECTO Chew for Dogs, 4.4–9.9 Lbs

This BRAVECTO chew targets small dogs within a compact weight range, delivering up to 12 weeks of flea and tick protection in a single dose. The chew format can simplify administration for owners who prefer not to apply topical products. Always verify the pet’s weight category to ensure appropriate dosing and long-lasting protection.
BRAVECTO Topical Solution for Cats, 13.8–27.5 Lbs

For cats on the higher end of the weight range, this BRAVECTO topical provides extended flea and tick protection up to 12 weeks per dose. The product format is designed for cats that tolerate topical applications well and aligns with a low-re-dosing plan for feline households. Confirm weight to ensure the correct dosage and duration of protection.

Buying Guide
Key considerations when choosing a 12-week flea and tick solution include pet weight and species, allergy history, and ease of administration. BRAVECTO products are available as topical solutions and chews, with feline and canine options tailored to weight ranges. For owners who prefer a daily preventive, long-acting options can reduce monthly dosing needs. Consider your pet’s lifestyle—indoor vs. outdoor, interaction with other animals, and potential exposure to ticks in your region.
Effectiveness and safety profiles should be reviewed with a veterinarian, particularly for pets with existing medical conditions, pregnant or lactating animals, or those taking other medications. With long-acting products, observe your pet for any adverse reactions after administration and ensure ongoing regular check-ins on weight, as dosing depends on weight ranges.
Compare formats (topical vs chew) for your household: topical applications may deter pets that dislike handling, while chews offer a treat-like experience that can improve acceptance. Remember to store products as directed and maintain a consistent dosing schedule to preserve full 12-week protection. For multi-pet households, verify each pet’s weight category to avoid dose errors and ensure species-specific safety.
