• Six-month supply: Reduces the need for monthly purchases and planning
• Waterproof formula: Maintains effectiveness even after baths or rain
• Breaks flea life cycle: Targets eggs and larvae to prevent re-infestation

Compared to single-dose or shorter-duration treatments, this option prioritizes long-term convenience and coverage. The tradeoff is that it’s specifically formulated for larger dogs, so it’s not suitable for smaller breeds.
