Thank you for submitting your question regarding Harley. I typically prescribe Vectra 3D once a puppy is 8 weeks of age. It is a flea and tick prevention, but also repels mosquitoes which aids in heartworm prevention. It provides protection against certain types of biting flies, lice and mites. I hope this information helps!
