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

Here's my experience with heartworms, which are only a problem in mosquito infested regions. Have 2 dogs, used the expensive heartworm meds vet was telling me to use. Both had heartworms within 1st year of their life. Vet basically wanted to do the Arsenic injections and crate for 6-8 weeks and charge me lots of money. I did some research, found some interesting studies about using doxycycline antibiotics. I did 2, 2-week antibiotic treatments with 2 week pause in between for both dogs and during this time switched to ivomec for cattle giving the correct dosage 1x per month. Still using ivomec now monthly. Took dogs back 6 months after ivome/doxy treatment and both are heartworm free.
