Many pet owners use a preventative like Heartgard Plus, but there is a generic equivalent to Heartgard Plus, which is Iverhart Max. Both products prevent heartworm disease and also control roundworms, hookworms. However, Iverhart Max also controls tapeworms, whereas Heartgard Pus does not.
Symptoms of heartworms in both cats and dogs are generally the same, which can involve vomiting, wheezing, choking, diarrhea, and a dull and an unkept coat. Because heartworm treatment can be potentially fatal, the best option to reduce your pet's risk of contracting the disease is by establishing heartworm control with a monthly preventative.
Monthly heartworm preventatives like Iverhart Max kill any heartworm larvae that may have transferred their way into the pet's body during the previous 30 to 45 days. Heartworm preventatives can only kill heartworm larva, not adult heartworms, which is one of the main reasons why prevention is essential in maintaining your pet's health.
