Question

Is it necessary to give dogs heartworm medicine?

Do dogs need to be given heartworm medication to prevent heartworms or do the dogs only need the heartworm medication when they get heartworms?

Answer 1

Yes it's recommended to give your dog heartworm medication year round to prevent heartworms.

Heartworms in dogs and cats are transmitted through mosquito bites. When mosquito activity is high your dog or cat will be more at risk for developing heartworms.
