K9 Advantix II Flea, Tick & Mosquito Protection - 2 Doses

Who is this product for?

K9 Advantix II is a monthly, broad-spectrum topical treatment for dogs and puppies 7 weeks and older, weighing 1.4 kg (3 lbs) or more. It is one of the most comprehensive parasite preventatives on the market, recommended by veterinarians. It is particularly suitable if you are looking for:

• Comprehensive 5-target protection — fleas, ticks, lice, mosquitoes, and stable flies
• Protection against Lyme disease — kills deer ticks (Ixodes scapularis), the main vector of Lyme disease in Quebec, where cases have been sharply increasing since 2020
• Pre-bite preventative action — parasites die on contact with the skin, without needing to bite your dog
• A waterproof formula that remains effective after shampooing, bathing, or swimming
• A repellent effect against mosquitoes and stable flies, which can transmit diseases
• Simple and quick application — just one application per month
• A veterinarian-recommended approach for active dogs, those who frequent forests, trails, dog parks, or rural areas

Active ingredients

• Imidacloprid 8.8% — kills adult fleas on contact by interfering with their nervous system
• Permethrin 44% — repels and kills ticks, mosquitoes, and stable flies. ⚠️ This ingredient is toxic to cats — never use on a cat.
• Pyriproxyfen 0.44% — growth regulator that prevents the development of flea eggs and larvae

How it works

K9 Advantix II is applied to the skin, along the dog's back. From there, it spreads evenly in a thin layer over the skin surface and attaches to the sebum, rather than being absorbed into the bloodstream.

When parasites such as fleas, ticks, mosquitoes, or lice come into contact with the treated dog's skin, their nervous system is immediately affected. Parasites quickly lose coordination and die — without having to bite your dog. This protects your pet from the discomfort of bites and can help prevent the transmission of diseases such as Lyme disease, heartworm, or anaplasmosis.

🚨 Critical precautions for households with cats

Important precautions

• External use only — do not ingest
• For dogs 7 weeks and older only, weighing 1.4 kg (3 lbs) or more
• Never use on a cat or rabbit — permethrin is toxic to these species
• Avoid contact with your dog's eyes and mouth
• Wash your hands after application
• Keep out of reach of children
• Avoid direct contact with the product for 24 hours after application
• Slight local irritation may occur; it usually disappears quickly
• Discontinue use and consult a veterinarian if you observe unusual signs (excessive salivation, lethargy, tremors, convulsions, loss of appetite)
• Do not use on sick, weakened, or elderly dogs without veterinary advice

Package contents

2 doses = 2 months of treatment. Each box contains 2 pre-dosed single-use tubes.

💡 Ideal for trying the product or for occasional protection (summer season, travel to tick-infested areas, hiking in the forest). For year-round protection, opt for a more economical prorated format.

Seasonal recommendation in Quebec

In Quebec, the tick season generally extends from March to November, but can begin as soon as the temperature exceeds 4 °C. For optimal protection against Lyme disease, it is recommended to treat your dog continuously during this period, especially if you frequent forests, hiking trails, dog parks, or rural areas.

Storage

Store at room temperature, away from direct sunlight and excessive heat. Keep out of reach of children and animals.
