We hear it every year. "I’ll start heartworm meds in July when the bugs are bad."
But here’s the reality for Canadian pets. Heartworm doesn't wait for Canada Day. Between urban hot spots (like sunny balconies and warm brick alleyways) and pets traveling to warmer climates, the risk of transmission can start weeks before the official mosquito season begins.
Why is spring shield month?
✅ An annual blood test ensures your pet hasn't carried an undiagnosed infection through the winter.
✅ Starting prevention in the early spring months builds a protective barrier before the peak mosquito swarm hits.
✅ It’s significantly easier (and far less costly) to prevent heartworm than it is to treat it.
