K9 Advantix II XL Dog Flea, 

Protecting our dogs from harmful parasites is one of the most important responsibilities we have as pet parents. K9 Advantix II XL Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention provides a trusted, effective, and long-lasting solution for large breed dogs weighing over 55 lbs. This comprehensive guide explores everything you need to know about this treatment—ingredients, benefits, safety, application, and why it stands as one of the top choices for parasite protection.

Why Choose K9 Advantix II for Extra-Large Dogs?

Large dogs are often more active and spend more time outdoors, making them especially vulnerable to fleas, ticks, and mosquitoes. K9 Advantix II XL is designed specifically for dogs over 55 lbs to deliver:

• Flea elimination – kills fleas on contact, before they bite.

• Tick protection – repels and kills ticks including deer ticks, lone star ticks, and brown dog ticks.

• Mosquito defense – repels mosquitoes that can transmit heartworm disease.

• Lice and biting fly control – prevents irritating infestations and discomfort.

• Water-resistant protection – continues working after bathing or swimming.

Active Ingredients and How They Work

K9 Advantix II XL combines three active ingredients for broad-spectrum protection:

• Imidacloprid – targets adult fleas by attacking their nervous system.

• Permethrin – repels and kills ticks, mosquitoes, and biting flies on contact.

• Pyriproxyfen – prevents flea eggs and larvae from developing, breaking the flea life cycle.

These ingredients work synergistically, ensuring comprehensive and long-lasting protection for your dog.
