Buying Guide: Key Purchase Considerations
- Dog size and weight: Choose products that match your dog’s weight range to ensure proper dosing and safety.
- Active ingredients: Fipronil and (S)-methoprene are common in topicals and work to kill fleas and disrupt their life cycle; collars like Seresto offer long-term protection without monthly dosing.
- Protection duration: Topicals typically provide 30 days of protection per dose, while some collars offer up to eight months. Consider your preference for application frequency.
- Environment and lifestyle: Active dogs or households with multiple pets may benefit from waterproof formulations and products with quick-reaction times after exposure.
- Safety and medical history: If your dog has allergies, skin sensitivity, or is pregnant or nursing, consult a veterinarian before starting any new flea and tick regimen.
- Resistance and life cycle control: Products that kill eggs and larvae help prevent reinfestation, not just adult fleas, which can reduce ongoing infestations in the home.
- Cost and convenience: Evaluate price per dose and the convenience of monthly applications versus longer-lasting options like collars.
