Hi Kathryn and welcome.
I'm so glad you're taking these cautious steps and are already raw feeding. As you'll see in reading my book, you'll have lots of company if you follow the protocol for drug free heartworm prevention! Best advice I can give is to surround yourself (even if that's online) with others who see the truth you are perceiving. There's no place for shaming on any vet's part. You have a brain, you can think for yourself and make good decisions based on carefully weighing evidence before you, and if the vet is not on board, that's his/her problem, not yours.
Tests usually don't just go negative on their own, no. Mr Piggy was treated homeopathically by me. That's why he tested negative.
We're glad you're here, Kathryn, and wish you and your Berners the best, most Vital long lives going forward!
