Hi Mona, and welcome!
Your question is timely, and I'd suggest you sign up for email updates on the website (scroll to the top of this page), as the next post in my series, "Stop Killing Your Pet: The Top 5 Ways" is about heartworm. It'll go out tomorrow. When you sign up for updates, you'll be the first to get blog posts and other interesting stuff from me.
To find holistic vets near you, visit my Resources page. You'll see a couple of listings there. One for holistic vets and another for a certain kind of holistic vet, we who are homeopathic vets.
I wish you the best with your animals on Galveson Island.
