Missing a dose of your dog’s monthly heartworm preventative can be concerning. Here’s what you should do:
Table of contents
Immediate Actions
If you realize you’ve missed a dose, give the missed dose immediately. Then, resume the regular monthly schedule.
When to Worry
A lapse of two months or longer requires immediate action and consultation with your veterinarian.
Heartworm Testing
Consider scheduling a heartworm test six months from the date of the missed dose. It takes approximately six months for heartworm infection to become detectable.
Consult Your Veterinarian
Consult your veterinarian for personalized advice, especially if the lapse was significant, or if you live in an area with a high mosquito population.
Why Consistency is Key
Heartworm preventatives work by eliminating heartworm larvae that have infected your dog in the past month. They don’t provide long-term protection; Skipping a dose leaves your dog vulnerable to infection during that period.
Risks of Skipping Doses
Even a single missed dose can increase the risk of heartworm infection. The longer the lapse, the greater the risk. Heartworm disease is a serious and potentially fatal condition. Treatment is expensive, can be hard on your dog, and doesn’t always guarantee a full recovery.
What About Yearly Heartworm Injections?
While a yearly heartworm injection (like ProHeart) offers continuous protection, it’s still crucial to maintain consistent prevention. Even with the injection, breakthrough infections are possible, though rare. Consult your veterinarian about the best prevention method for your dog’s lifestyle and risk factors.
Tips for Remembering Doses
- Set a Reminder: Use your phone, calendar, or a medication reminder app to ensure you never miss a dose;
- Tie it to a Routine: Give the heartworm medication on the same day each month, coinciding with a regular activity (e.g., grooming day, paying bills).
- Visual Cues: Leave the medication in a visible spot, like near your dog’s food bowl or leash.
- Automatic Refills: Set up automatic refills through your veterinarian or a reliable online pharmacy.
When to Consider Additional Precautions
If you live in a region with a year-round mosquito season, or if your dog spends a lot of time outdoors, consider additional mosquito control measures, such as:
- Mosquito Repellents: Use dog-safe mosquito repellents, as recommended by your veterinarian.
- Limit Outdoor Exposure: Reduce outdoor activity during peak mosquito hours (dawn and dusk).
- Eliminate Standing Water: Remove any sources of standing water around your property, as these are breeding grounds for mosquitoes.
