Why your Dog Need Heartgard Plus?

How Does Heartgard Plus for Large Dogs Work?

Heartgard Plus contains ivermectin and pyrantel pamoate, two potent antiparasitic agents:

• Ivermectin: Prevents heartworm disease by eliminating Dirofilaria immitis larvae before they mature into adult heartworms.
• Pyrantel Pamoate: Effectively treats and controls common intestinal worms, including Toxocara canis (roundworm) and Ancylostoma caninum (hookworm).

Heartworm disease is transmitted through mosquito bites, making prevention crucial year-round. Once infected, treatment for heartworm disease is expensive, risky, and does not guarantee recovery. Monthly administration of Heartgard Plus ensures continuous protection and peace of mind.

Dosage and Administration

Always consult your veterinarian for exact dosage instructions based on your dog’s weight.

How to Give Heartgard Plus to Your Dog

• Remove one chewable from the foil-backed blister pack.
• Offer it to your dog as a treat or mix it with a small amount of food.
• Ensure your dog chews the tablet rather than swallowing it whole.
• Observe your dog for a few minutes to confirm the full dose is consumed.
• If a dose is missed, give it as soon as possible and resume the regular schedule.

For best results, administer Heartgard Plus on the same day each month to maintain consistent protection.
