I do recommend monthly heartworm prevention starting at 8 weeks of age. It is a prescription so a veterinarian does not have to personally give the pill but you need to either buy it from a vet or get a prescription from a vet. The only medication that needed to be at a veterinarian's office is Pro-heart. This is an injectable heartworm prevention that lasts for 6 months. Thank you for using Petco Pet Education Center, formerly Petcoach.
