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.
