re: Update in OP; Treating young lab for heart worms

Slow Kills? Are we talking the antibiotic route? My understanding is that Heart Worm medicine is given every month to kill new worms introduced into the body via mosquito reinfection. It is correct that the normal monthly meds do not kill adult worms. The antibiotic, from my research, combat a microbe in the gut of all heartworms need ed for digestion and severely reduces the life expectancy of adult worms. Like I mentioned before, 6 months after completing treatment, my dogs were heart worm free.
