Dosage

Heartgard For Dogs should be given orally once every month. Ideally, the medicine should be given on the same day of every month. To help you remember the day when you must administer Heartgard, the medicine’s package comes with stickers. Use them so that your dog won’t miss a single dose. Heartgard becomes less effective when you fail to give the right doses. Ivermectin, an active ingredient in Heartgard, kills growing heartworms in a dog’s heart. And if your dog misses his Heartgard doses, the heartworms might grow to the extent that the medicine could no longer fight them. The medicine must also be administered monthly for the rest of your dog’s lifetime.

Overdosage is not good for your dog, either. Be careful not to give your pet more than what is indicated in the product’s label. But once it happens, seek medical help from your vet. Signs of Heartgard overdose include weight loss, diarrhea, and vomiting.
