I am a holistic dog breeder and use no vaccines on my puppies or adults. Although I do rabies as it is the law. I use Thuja afterward for detoxing.
I use no heartworm preventative, you can read more about that on my website. I will be posting new information soon about holistic vets who have successfully use Black-Walnut Hull as a preventative and a cure for heartworm.
My website is full of information about doggie diseases and problems. I try to educate the public. So many of us just do what we are told without asking any questions.
Check out my website and hopefully you will see there are many alternatives that work.
