Please note the following:
1. Heartworm Preventative can only be refilled with a current exam and current heartworm test and may take up to 72 business hours for approval. A rush fee may be applied if the preventative is needed sooner.
2. If your pet has missed more than 2 doses (more than 60 days without prevention) but not more than 6 doses (6 months) you may restart heartworm prevention without testing. If your pet has missed more than 6 months of preventative a heartworm test is required prior to restarting to ensure they are not positive. In addition to their annual testing, if there has been a gap in treatment of more than 60 days we recommend performing a heartworm test 6 months after restarting to ensure your dog is not positive.
3. Please note that we do not work directly with online pharmacies. Some, like Chewy, now require a hard copy of the written prescription to be mailed directly to them. We will always prepare a written prescription for you to pick up upon request.
