How often should I apply Frontline Spot On for Dogs?
- For the prevention of flea infestations: Apply every 2 months.
- To treat a severe flea infestation: Apply every 4 weeks for 12-16 weeks to bring the flea population under control.
- To protect your dog from ticks: Apply every 4 weeks. Frontline Spot On is not a tick repellent so you may still see some ticks on your pet, but they should be killed within 48 hours.
