ProHeart 6 for Dogs
Brand: Zoetis
ProHeart 6 is a long-acting, injectable heartworm preventative manufactured by Zoetis that provides six months of continuous protection for dogs with a single clinical administration.
This product is intended for dogs.
Overview
ProHeart 6 is a revolutionary advancement in veterinary medicine designed to eliminate the risks associated with missed monthly doses of oral heartworm medications. As a sustained-release injectable suspension containing moxidectin, this medication is administered exclusively by licensed veterinarians to ensure accurate dosing and compliance. Unlike traditional monthly preventatives, such as Advantage Multi for Dogs, which require diligent owner oversight, ProHeart 6 offers peace of mind by remaining active in the dog's system for a full six-month duration, effectively preventing heartworm disease caused by Dirofilaria immitis. By utilizing microsphere technology, the medication is slowly released into the subcutaneous tissue, maintaining therapeutic levels long after the visit to the clinic. This unique delivery mechanism distinguishes it from other oral heartworm treatments like Valuheart or Nuheart, which rely on daily or monthly owner administration. By providing a clinical alternative, it mitigates the common issue of owner non-compliance that often leaves dogs vulnerable to infection. Furthermore, because it is administered in a controlled setting, it is not a substitute for products like Milbemax or HeartShield Plus that pet owners purchase for at-home use, but rather a professional service intended to provide reliable, long-term coverage. It is vital to note that this product is strictly for canine use and must be administered under professional supervision. Unlike early heartworm medications such as Diethylcarbamazine which were used historically, ProHeart 6 utilizes modern pharmacological developments to ensure high efficacy and safety profiles when used according to the label requirements. While options like Cardotek Plus remain available, those seeking a set-it-and-forget-it solution often choose this injectable to bridge the gaps that occur in traditional regimens.
What It's For
- Heartworm Prevention: It prevents heartworm disease by eliminating the immature stages of Dirofilaria immitis.
- Compliance Assurance: It eliminates the potential for missed monthly doses, ensuring consistent parasite protection.
- Broad Parasite Management: It also treats existing hookworm infections (Ancylostoma caninum, Uncinaria stenocephala) present at the time of administration.
How To Use
ProHeart 6 must be administered only by a licensed veterinarian or under their direct supervision. The veterinarian will weigh your dog to determine the precise dose based on body weight, as inaccurate dosing can compromise efficacy or increase risk. The medication is delivered via a subcutaneous injection, typically placed in the neck or shoulder region, ensuring the microspheres are correctly deposited for slow, steady release into the bloodstream over the next six months. Because it is a controlled, medical-grade procedure, owners cannot purchase this for at-home administration. Before the injection is given, your veterinarian will perform a heartworm test to ensure the dog is currently negative for adult heartworms, as administering preventatives to a positive dog requires different management protocols. Following the administration, the clinic will typically provide a reminder for when the next six-month dose is due, ensuring continuous, year-round protection.
Precautions
ProHeart 6 should not be administered to dogs that are sick, debilitated, underweight, or have a history of weight loss, as clinical health must be stable to ensure proper absorption. Use with caution in dogs with pre-existing conditions or hypersensitivities to moxidectin. It is contraindicated for use in dogs that are pregnant, nursing, or intended for breeding, as safety in these groups has not been adequately established. Owners should monitor their dogs closely for any signs of adverse reactions, such as lethargy, vomiting, or swelling at the injection site, and report them to a veterinarian immediately if they occur.
