Heartworms
A serious and potentially deadly disease.
Heartworms—long, spaghetti-like worms that can grow 10-inches in length—live in the hearts, lungs and bloodstreams of infected dogs. Heartworm disease is spread when a mosquito bites an infected dog. Microfilariae in the dog's blood mature into infective larvae in the mosquito, which are transferred to another dog by the mosquito's bite. In approximately six months, the larvae mature into adult heartworms.
Untreated, heartworms can lead to death in dogs. These are undoubtedly among the most devastating of canine parasites. Fortunately, needless pain and suffering can be prevented with an annual heartworm test and the medicine formulated with the trusted actives veterinarians have prescribed for years, which are found in IVERHART MAX® and IVERHART PLUS®.

In clinical field trials, the most common adverse reactions, vomiting and diarrhea, were rarely observed (1.1% of doses administered). For more information, ask your veterinarian.
