Discover everything you need to know about K9 Advantix II for dogs

Choosing a parasite treatment raises questions about your dog's health. To help you, our experts have compiled the most common questions about Elanco solutions in Canada. If you have any further questions, please feel free to discuss them with a Ren's Pets advisor, who will be happy to assist you. 

What is K9 Advantix II and how does it work? 

K9 Advantix II is a monthly topical treatment that bonds with your dog's natural skin oils to create a repellent barrier. 

The formula combines three active ingredients (imidacloprid, permethrin, and pyriproxyfen) to eliminate and repel parasites before they have the chance to bite. This proactive shield is essential for preventing the allergic reactions and skin irritations often caused by pest stings. 

How to apply K9 Advantix II? 

K9 Advantix II comes in a pipette precisely measured for your dog's weight. To ensure maximum effectiveness, you must apply the entire contents of the tube directly to the skin. 

1. Prepare the spot: Part the fur at several points along your dog's back, from the shoulder blades to the base of the tail, until the skin is visible. 
2. Apply directly: Squeeze the tube firmly to apply the liquid directly onto the skin. Spreading the dose across three or four points along the spine helps prevent your dog from reaching the product to lick it off. 
3. Let it dry: Allow the solution to dry naturally. Avoid rubbing the product into the fur, as it needs to bond with the skin to work effectively. 

Apply the product uniformly directly onto the skin surface at several points along your dog's back. Do not rub the product and allow it to dry naturally. 

What are the differences between K9 Advantix II and Advantage II for dogs? 

Selecting the most effective flea treatment for dogs depends on your pet’s lifestyle and the level of protection they need. While both are trusted solutions from Elanco, Advantage II and K9 Advantix II serve different purposes. 

• Advantage II is specifically designed to eliminate fleas and lice at all life stages 
• K9 Advantix II offers a broader defense by also repelling and killing ticks, mosquitoes, and biting flies.  

If your dog frequently explores wooded areas or tall grass where ticks are prevalent, K9 Advantix II is the recommended choice for comprehensive protection. 

Review the comparison below to determine which formula best suits your dog's specific needs: 

Is K9 Advantix II safe? 

K9 Advantix II is highly safe for dogs when used strictly according to the label instructions. As a topical treatment, it remains on the skin and is not absorbed into the bloodstream. You must ensure the correct dosage is applied based on your dog's specific weight to maintain optimal safety. 

As your local pet shop experts, we recommend choosing from the four distinct formats: 

• K9 Advantix II for small dogs weighing up to 4.5 kg 
• K9 Advantix II for medium dogs weighing between 4.6 kg and 11 kg 
• K9 Advantix II for large dogs weighing between 11 kg and 25 kg 
• K9 Advantix II for extra large dogs weighing over 25 kg 

Does K9 Advantix have any side effects? 

While K9 Advantix II is safe for most dogs, rare side effects may occur depending on your pet's individual sensitivity. The most common issues include temporary redness, irritation, or itching at the application site. 

If these symptoms persist or become more severe, please contact your veterinarian immediately for guidance. 

How quickly does K9 Advantix II work and how long does it last? 

You will begin to see the first positive effects within 12 hours of applying K9 Advantix II. Once the formula integrates your pet's natural skin oils, it creates an active repellent barrier against ticks and mosquitoes. 

Each application provides a full month of broad-spectrum defense. Because ticks in Canada become active as soon as the temperature hits 4°C, our Ren’s Pets experts recommend starting your monthly treatment early in the season to ensure your companion remains protected year-round. 

Is K9 Advantix II waterproof for my dog? 

Yes, K9 Advantix II is a waterproof formula, meaning your dog stays protected even if they get wet. Once the treatment has bonded with the skin, it remains effective after swimming or bathing. 

To ensure the repellent barrier is fully set, our experts recommend waiting 24 to 48 hours after application before letting your dog in the water. For the best results, always use a mild, non-medicated shampoo to preserve the treatment's integrity throughout the month. 

What should I do if my dog licks the product? 

Preventing your pet from licking K9 Advantix II is essential, as the bitter taste can cause temporary nausea or excessive drooling. If your dog does lick the area, we recommend rinsing their mouth with fresh water. We recommend that you keep an eye on your dog for the first 2 hours after applying the product and keep your pets in separate rooms until the treatment has dried. 

If your dog ingests a significant amount of the product or exhibits any abnormal behavior, please contact your veterinarian immediately. 

Is it safe to apply K9 Advantix II to my cat? 

You must never use K9 Advantix II on a cat. This formula contains ingredients that are specifically designed for dogs but are highly toxic and potentially fatal to felines. To ensure your pet's safety, always choose a dedicated flea treatment for cats. 

If you are looking for a reliable solution for your feline companion, we recommend browsing our Advantage II for cats options. Using a species-specific product is the only way to guarantee effective protection without putting your cat’s health at risk
