Heartworm is one of the most serious parasitic infections dogs can face, and it falls on owners to provide them with the proper preventative medications. Many heartworm medications are combined with flea and tick treatments for what veterinarians call a broad-spectrum approach. However, there are also stand-alone heartworm medications that specifically target opportunistic parasites such as heartworm, hookworm and roundworm. Heartworm medications are generally administered once a month, and are often sold as chewable tablets or easy-to-apply topical solutions. If heartworms are allowed to reach the adult stage without medical intervention, the results can be fatal. This is why finding and administering the right prescription heartworm preventative medication is so important.
