I missed a dose of my pet’s heartworm prevention, what do I do?

If it has been less than 45 days, we recommend giving her dose like normal and having a heartworm test performed in 6 months. If it has been over 45 days, we must do a heartworm test before selling any additional prevention.

Yearly heartworm tests are required in order to purchase heartworm prevention. The test must be negative for the safety of your pet.
