K9 Advantix II vs Frontline Plus

Compare K9 Advantix II Spot-On to Frontline Plus Spot-On

Despite the development of chewable options, monthly spot-on treatmentsremain a popular way of treating fleas and ticks on dogs and cats. Topicals kill parasites through contact, rather than biting and feeding, saving your pet from discomfort.

K9 Advantix II and Frontline Plus are two of the leading topical products on the market, both offering month-long protection against fleas and ticks. Not only do they kill adult fleas, but eliminate flea eggs and larvae before they can develop.

The key difference between these two popular treatments is that Frontline Plus is available for both dogs and cats, while Advantix II is a dog-only product. However, Frontline Plus for dogs must not be used on cats.

Frontline Plus is for use only on dogs and cats over 8 weeks of age, while Advantix II is suitable for dogs as young as 7 weeks. Please ensure that you have the correct product for your pet’s body weight.
