Veterinarian Review (Michael Dym, VMD)

In my experience and opinion, the main ingredient ivermectin in this once monthly heartworm preventative is the most effective preventative for canine heartworm. Under veterinary supervision, it can even be an alternative TREATMENT in treating active heartworm infections when used monthly in those dogs who are either too old for the expensive conventional immiticide drug treatment, or where risks of immiticide treatment outweigh the benefits. This should be discussed with your pets veterinarian. Pets can often clear heartworm infection after 12-24 months of consecutive use, again best done under veterinary guidance. With its other main ingredient, pyrantel, heartguard plus is the most effective preventative in controlling/treating/preventing roundworm and hookworm infection in dogs. Dogs also seem to prefer the taste of this beef flavored chewable tablet. The main disadvantage is of this product is in those situations where pets have tested positive for whipworms on stool checks. This preventative does NOT prevent or control whipworm infections, which can cause inflammation of the colon/diarrhea, and be difficult to control in affected dogs.

Given the rapidly expanding world of generics in the human pharmaceutical industry, it is indeed a pleasure for me as a practitioner of 16 years or experience to also see the same cost saving but equally as effective alternatives in the veterinary field as well. Heartworm disease is on the increase again in the United States. And given the importance and sometimes difficulty of client compliance in keeping up with costly monthly heartworm preventative medicines, it is great that Merck Animal Health has offered a generic version like Tri-Heart Plus to help meet this continued threat. Hopefully the savings on this preventative will encourage even more clients to have their pets on year round internal parasite control against the year round threat of heartworms, roundworms and hookworms. Tri-Heart Plus is quite safe in as pups as young as 6 weeks of age, as well as pregnant and nursing dogs. While I would rather have seen a beef flavored chewable over the pork flavor, dogs seem to love this pill just the same. The only disadvantage I have seen is very rare digestive upset in some patients which could be from the ivermectin or pyrantel main ingredients, or possibly from the pork flavoring.
