Vet’s typically recommend year round flea/tick prevention as even in the winter fleas are seen during unseasonably warm weeks. As warmer days are likely in the coming month of March I would start now. In general, the oral flea /tick preventatives such as monthly Nexgard, Simparica or every 12 weeks Bravecto chews are more effective than topical products such as Frontline without the risk of skin sensitivity. When you run out of your current product, before the warmer spring months arrive, definitely inquire with your vet about the oral flea/tick products. Great job for being so proactive of an owner in protecting Snowball!
