Why I Believe Knowing the Difference Between K9 Advantix and K9 Advantix II is Essential

As a dog owner, I have always been conscious about my pet’s health and well-being. This includes taking necessary measures to protect him from fleas, ticks, and other harmful parasites. When it comes to flea and tick prevention, two popular options are K9 Advantix and K9 Advantix II. While both are effective in keeping these pests at bay, there are some key differences between the two that every pet owner should be aware of.

Firstly, K9 Advantix is a topical solution that needs to be applied once a month on the dog’s skin. On the other hand, K9 Advantix II has an improved formula that provides longer protection with just one application per month. This means less hassle for me as a pet owner and more convenience for my dog.

Additionally, K9 Advantix II not only repels but also kills fleas, ticks, and mosquitoes on contact. This is crucial as it not only prevents infestations but also eliminates existing ones. On the contrary, K9 Advantix only repels these pests but does not kill them upon contact.

My Buying Guide on ‘Difference Between K9 Advantix And K9 Advantix Ii’

As a pet owner, I am always looking for the best products to keep my furry friend safe and healthy. When it comes to flea and tick prevention, two popular options are K9 Advantix and K9 Advantix II. At first glance, these two products may seem similar, but there are some key differences that every pet owner should be aware of before making a purchase. In this buying guide, I will break down the differences between K9 Advantix and K9 Advantix II to help you make an informed decision.

Active Ingredients

The first major difference between these two products is their active ingredients. While both contain imidacloprid and permethrin, K9 Advantix II also includes pyriproxyfen. Pyriproxyfen is an insect growth regulator that prevents flea eggs and larvae from developing into adult fleas. This means that while both products kill adult fleas and ticks, only K9 Advantix II can also prevent future infestations by stopping the next generation of fleas from hatching.

Protection Against Parasites

While both products provide protection against fleas and ticks, they differ in the specific parasites they target. K9 Advantix protects against fleas, ticks, biting flies, mosquitoes, lice, and mites. On the other hand, K9 Advantix II provides protection against all of these parasites plus adds protection against flea eggs and larvae.

Application Frequency

Another notable difference between these two products is how often they need to be applied. K9 Advantix should be applied once a month for continuous protection against fleas and ticks. However, K9 Advantix II has a longer-lasting formula that only needs to be applied once every four weeks.

Suitable for Different Dog Sizes

K9 Advantix is suitable for dogs that weigh at least 7 pounds while K9 Advantix II is suitable for dogs that weigh at least 4 pounds. This makes K9 Advantix II a better option for smaller breeds or puppies.

Waterproof vs Water-Resistant

Both products claim to be waterproof or water-resistant; however, there is a slight difference between them. While both can withstand bathing or swimming within 48 hours of application without losing effectiveness, only K9 Advantix II remains effective after bathing or swimming more than once within those 48 hours.

Pricing

Pricing can also play a role in your decision between these two products. In general, K9 Advantix II tends to be slightly more expensive than regular K9 Advan
