ProHeart 12 for Dogs
Brand: Zoetis
ProHeart 12 is a professional-grade, injectable prescription medication from Zoetis that provides 12 continuous months of heartworm disease protection for dogs with a single dose.
This product is intended for dogs.
Overview
ProHeart 12 is a revolutionary long-acting injectable parasiticide developed by Zoetis, specifically engineered to simplify canine health maintenance through a sustained-release delivery system. Unlike traditional oral preventatives such as ProHeart 6, which requires a six-month administration schedule, or older medications like Filaribits Plus, this product utilizes advanced microsphere technology to release moxidectin steadily over the course of an entire year. This innovation effectively eliminates the common struggle of monthly pill compliance, ensuring that dogs remain shielded from heartworm larvae without the risk of owner forgetfulness. While topical options like Advantage Multi for Dogs are effective for surface-level pests, ProHeart 12 focuses exclusively on internal systemic protection. Historically, pet owners had to rely on daily medications like Dimmitrol or older heartworm prevention staples like Valuheart to maintain coverage. By transitioning to a once-a-year clinical injection, veterinarians can guarantee that patients receive the exact dosage necessary for year-round immunity. Furthermore, it avoids the complexities associated with managing multiple doses of HeartShield Plus, providing a streamlined standard of care for modern households. For those who previously utilized Cardotek Plus or generic equivalents like Nuheart, this injectable represents a significant leap forward in preventative veterinary medicine. The consistency of the dosage removes the 'forgotten dose' gap that often leads to infections, making it a gold standard in heartworm disease prevention programs compared to oral alternatives like PetArmor Heartgard Generic.
What It's For
- Heartworm Disease Prevention: Kills Dirofilaria immitis larvae to prevent the development of mature adult heartworms.
- Treatment of Existing Hookworm Infections: Effectively clears and controls specific species of hookworms (Ancylostoma caninum and Uncinaria stenocephala) present at the time of injection.
How To Use
ProHeart 12 is exclusively administered by a licensed veterinarian as a subcutaneous injection under the skin. Before the administration, the dog must be tested for existing heartworm infection; if the dog tests positive, the veterinarian will need to discuss appropriate treatment protocols as injecting a positive dog can trigger a hypersensitivity reaction. The veterinarian will calculate the dosage based on the dog's exact body weight, ensuring the microspheres are injected properly into the tissue to allow for the slow, controlled release of the active ingredient over the following 12 months. Following the procedure, your pet should remain under observation at the clinic for a short period to ensure there are no acute reactions to the injection. Because this is a long-acting formula, there is no need for home administration or secondary monthly heartworm tablets. Pet owners are advised to maintain a strict annual schedule for their dog’s check-up, as the preventative efficacy lasts for exactly one year and requires a follow-up injection to maintain continued coverage without any gaps in protection.
Precautions
ProHeart 12 should not be used in dogs that have an existing heartworm infection or are exhibiting signs of systemic illness without prior veterinary intervention. It is strictly contraindicated for use in breeding, pregnant, or lactating females, as the safety of the active ingredient has not been established in these populations. Additionally, the injection should be used with caution in dogs that have a history of hypersensitivity or drug reactions. Pet owners should monitor their dog closely for 24 to 48 hours following the injection for signs of adverse reactions, such as lethargy, vomiting, or skin inflammation at the injection site. If any signs of an allergic reaction occur, such as facial swelling or difficulty breathing, contact your veterinarian immediately. It is essential to ensure that your pet's health status is reviewed annually during their wellness exam to confirm they are eligible for the next yearly dose.
