What time of year do you start k9 advantix?

You should start applying K9 Advantix when the weather begins to warm up and fleas, ticks, and mosquitoes are more active, which typically occurs in spring. It's important to continue using it throughout the warmer months, ideally year-round, especially in areas with milder climates. Be sure to follow the manufacturer's recommendations for frequency and application based on your dog's weight and lifestyle. Always consult your veterinarian if you're unsure about the best time to start.
