Hi Losul,
I just came across your thread. I went through a very similar process with my pointer.. I read MANY studies and talked to some of the heartworm experts. I had the whole diagnostic panel with x Ray and ultrasound done. I live in a dry, western state but adopted a dog from Texas that popped positive for HW. Based upon everything I learned and against the advice of the university vet ( my own vet was agreeable to the slow kill), I decided to go doxy with advantage multi. My dog had some interesting short term platelet numbers on lab results about 3.5 months into the treatment. I came to the conclusion it was probably worm die off. It resolved itself in about a week. The heartworm business is A BUSINESS! It’s so unfortunate, because I think that dogs with low worm burdens and their owners could be saved some pain and discomfort with this slow kill method. I plan on testing my girl at 7 months and agin at a year if she’s still positive.
