We are thinking of adopting a dog that is heartworm positive-she has already been started on the slow kill method but is scheduled to have the "fast kill" shot later in November. From what I have read here, slow kill is better, correct?Is it expensive? We would be completely new to this so if anyone have experience, please share.
@RogueHippEE: When I adopted my Becca she was Heartworm positive. I would 100% discuss this with a vet. It was my understanding you did not want to mix the slow kill (which is not always successful and can take a year or more) with the fast kill but that may have just been the vet? Need to consider the age of the dog, type of dog etc.  
lus on the slow kill I understand there is always the possibility of complications such as a blood clot to the lungs etc while the worms are dying. I did a lot of research on this before deciding the options considering Becca was only a year old.The fast kill went really well with Becca and she was heart worm free in 6 six as opposed to waiting a year +/-. The cost was $671.00 (she is about 30 lbs). She tolerated it well.. She just did not like have to always be outside on a leash for 3 weeks but we made it through. I also contacted the rescue I got her from and they paid 1/2 of the treatment.
