🐾 My Pet Is on Prevention—Why Do They Still Need Annual 4DX Testing?
Prevention protects 💪 Testing verifies ✅ That’s why we recommend annual 4DX testing, even for pets receiving heartworm and tick prevention.
4DX testing is a quick blood test that:
✅ Screens for heartworm disease, Lyme disease, Ehrlichiosis, and Anaplasmosis
✅ Confirms your prevention program is working
✅ Early detection means earlier treatment—helping reduce complications and improve your pet’s long-term health
🛡️ Many manufacturers back their heartworm and tick prevention products with guarantees. However, these guarantees typically require both continuous prevention and annual testing.
🐾 Annual testing provides peace of mind that your pet’s prevention plan is doing its job—so you can spend more time enjoying life’s adventures together 💙
