Frontline Plus vs. K9 Advantix II

Comparison between Frontline Plus Spot-On and K9 Advantix II Spot-On

Multiple chewable options are available, but Spot-on treatments are still the most popular way of treating ticks and fleas in cats and dogs. Spot-On kills parasites by contact, not from biting, and it will comfort your pet.

Frontline Plus and K9 Advantix II are the leading products in the market. Both of them provide full month protection from fleas and ticks. In addition, they will kill adult fleas and eliminate larvae and flea eggs before they develop.

One key difference between these two products is that Frontline is available for cats and dogs, while K9 Advantix II is only available for dogs. 

Frontline Plus is safe to use on cats and dogs at the age of eight weeks, and Advantix II is safe to use at the age of seven weeks.

Please choose the correct size according to your pet's body weight.
