Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Guard your large dog with a trusted, odorless topically-applied defense—Elanco K9 Advantix II Liquid Dog Flea Drops. This boxed set provides four convenient 0.34 oz doses in a single package, designed for ongoing protection without the guesswork. The formula blends Imidacloprid, Permethrin, and Pyriproxyfen for broad-spectrum flea and parasite control that works where your dog lives, plays, and travels.

Triple-action protection in one easy application

Imidacloprid swiftly targets adult fleas on contact, interrupting the flea lifecycle and helping reduce itching and discomfort. Permethrin adds a powerful repellent and killer effect against ticks and mosquitoes, helping keep your dog safer during outdoor adventures. Pyriproxyfen disrupts flea reproduction by preventing eggs from maturing, helping to curb new infestations over time. The result is a comprehensive approach that tackles fleas at multiple stages while deterring pests that commonly bother dogs outdoors.

Why this matters for large dogs

  • Specifically formulated for large dogs, delivering reliable coverage across the back and torso where pests frequently settle.
  • Odorless formula means less fragrance in your daily routine and fewer distractions for sensitive dogs.
  • Ready-to-use, non-concentrated liquid that’s simple to apply as part of your regular grooming or outdoor-ready regime.
  • The 4-dose box makes it easy to maintain protection across weeks or months without reordering frequently.

What problems it solves

This product addresses common concerns for dogs that roam yards, parks, or trails: fleas that cause irritation and itching, ticks that pose a risk of disease, and mosquitoes that irritate and bite. By combining a fast-acting flea control with tick and mosquito defense and an insect growth regulator, it helps reduce the likelihood of infestations and the need for frequent reapplications.

Ideal use scenarios

  • Dogs that spend time in grassy or wooded areas where fleas and ticks are prevalent.
  • Homes with multiple pets or families seeking a straightforward, box-contained solution.
  • Owners who prefer an odorless, topical treatment that integrates smoothly into a routine without added mess.

How this differs from other options

Compared with bite-sized sprays or collars, this topical triple-action formula provides systemic protection that travels with your dog’s skin oil and fur, offering continuous coverage between applications. The combination of adult-killing, repellent, and growth-regulating ingredients helps address fleas at several life stages, reducing re-infestation more effectively than single-action products. And with four doses in one box, you’re equipped for consistent protection over a longer period, without frequent repurchases.

Practical tips for best results

  • Store in a cool, dry place and use as directed on the label for your large dog’s size and weight class.
  • Use the product as part of a broader parasite prevention plan, including regular grooming and yard cleanliness to reduce pest habitats.
  • Monitor your dog after first application for any skin sensitivity and consult a veterinarian if you notice unusual reactions.

With Elanco K9 Advantix II, you’re choosing a proven, odorless topical solution that delivers targeted flea, tick, and mosquito defense for large dogs—packaged in a practical 4-dose box to support steady, convenient protection.
