Introduction to Heartgard
Heartgard is a popular heartworm preventative medication for dogs that is given once a month. It is available in various sizes and flavors to suit different dog breeds and tastes. Heartgard is an effective preventive medication that helps to protect dogs from heartworm disease, which is caused by a parasitic worm that is transmitted by mosquitoes.
Heartgard is a prescription medication that should only be used under the guidance of a veterinarian. It is important to follow the dosage and administration instructions carefully to ensure the safety and effectiveness of the medication. Heartgard should not be used in dogs that are allergic to any of its ingredients or have a history of heartworm disease.
The active ingredient in Heartgard
The active ingredient in Heartgard is ivermectin, which is a type of antiparasitic medication. Ivermectin works by paralyzing and killing heartworm larvae that are present in the bloodstream of dogs. It also helps to prevent further infection by killing the immature heartworms before they can reach maturity and cause damage to the heart and lungs.
Ivermectin can be toxic to some dog breeds, especially those that have a genetic mutation that makes them more sensitive to the medication. This mutation is more common in herding breeds such as Collies, Shetland Sheepdogs, and Australian Shepherds. These breeds may experience adverse effects at lower doses of ivermectin than other breeds.
Heartgard dosage for dogs
The dosage of Heartgard depends on the weight of the dog and the strength of the medication. It is important to follow the dosage instructions carefully to ensure that the dog receives the correct amount of medication. Overdosing on Heartgard can lead to toxicity and serious adverse effects.
Clinical signs of Heartgard toxicity
The clinical signs of Heartgard toxicity can vary depending on the severity of the overdose and the sensitivity of the dog. Some common signs include vomiting, diarrhea, loss of appetite, lethargy, weakness, tremors, seizures, and coma. In severe cases, Heartgard toxicity can be fatal.
Adverse reactions to Heartgard
Some dogs may experience adverse reactions to Heartgard even when the medication is administered at the correct dosage. These reactions may include vomiting, diarrhea, lethargy, loss of appetite, and allergic reactions such as itching, hives, and swelling of the face, lips, and tongue. If any of these reactions occur, it is important to contact a veterinarian immediately.
Heartgard contraindications
Heartgard should not be used in dogs that are allergic to any of its ingredients, have a history of heartworm disease, or are under 6 weeks of age.

Pregnant or nursing dogs should only be given Heartgard under the guidance of a veterinarian.
