Notes

K9 Advantix II offers more comprehensive protection than many competitors by targeting multiple parasite types. The repellent action is particularly valuable because it kills ticks before they can attach and transmit diseases like Lyme disease, which requires 24-48 hours of attachment. The mosquito repellent action helps protect against heartworm-carrying mosquitoes (though it's not a heartworm preventive itself—use a separate heartworm preventive as directed by your vet). Critical Safety Warning: This product is toxic to cats due to permethrin content. Keep treated dogs away from cats for 24 hours after application. If you have both dogs and cats, consider cat-safe alternatives. Some dogs may experience mild skin irritation at application site—monitor and contact vet if irritation persists. Always use the correct weight range product.
