I have heard there is a once-a-year shot to prevent heartworms in dogs. Does it work? Is it safe?
DR. MCMILLAN'S ANSWER:
The Proheart 12 injection is the once-a-year heartworm preventative you're talking about most likely. It was approved and released in 2019. We actually participated in the company's clinical trials for Proheart 12, and we have used it extensively for our clients' dogs since it came on the market. We were impressed with its safety during the trials. While it's new here in the U.S. to many people, this preventative has been approved in Australia since 2001. It is the most commonly used heartworm preventative in that country, and as such, has had an excellent safety profile with millions of doses given.
