Honestly, there's not much you can do. The extra dose *shouldn't* hurt your dog, although we certainly wouldn't recommend making extra doses a regular occurrence. Try to keep an eye out for any negative side effects that may be occurring due to the extra dose. Things to look out for include: vomiting, diarrhea, excessive panting, excessive thirst, rapid heart beat, shivering, weakness, facial swelling, hives, shock, and seizures. If any of these things occur, or even if you're just worried, call your vet! That's what your vet is there for. To avoid having your dog get extra doses, consider signing up for email reminders. You can sign up directly through HeartGard or use a generic reminder service like Pet Meds Reminder Service. more

According to the Merial website, toxicity occurs at 10x the recommended dose in sensitive collies (I think collies are more sensitive to Ivermectin in general).
