How to Choose

• Lifestyle and environment: If your dog goes hiking or lives near woods, choose a product that repels or kills ticks (e.g., K9 Advantix II). For indoor-only cats, a basic flea product like Revolution may suffice.
• Ease of administration: Oral chews (NexGard, Bravecto) are great for dogs that dislike topical, while collars (Seresto) work for forgetful owners. Topicals (Frontline) are easy but can be messy.
• Duration of protection: Bravecto offers 12 weeks per dose, while most others are monthly. Collars last 8 months. Consider how often you want to reapply.
• Budget: Compare per-month costs. Collars have a higher initial cost but lower monthly average. Topicals like Advantage II are cheapest for small dogs.
• Health considerations: Dogs with a history of seizures should avoid oral options like NexGard. Always check with your vet, especially for puppies or senior pets.
• Additional benefits: Some products also prevent heartworm (Revolution) or repel mosquitoes (K9 Advantix II). If you want multi-purpose, choose accordingly.
