and the slow kill method is absolutely NOT a recommended method of HW treatment.
It absolutely is here. A month of doxycycline followed by monthly doses of HW prevention and yearly tests and bloodwork to track the status.
I don't know how you plan on doing the fast kill with no immiticide? No clinic in my state has had access to it except for EMERGENCY and special cases since August at least, I think is the first time I saw the letter circulate...I actually read the letter myself FROM the company at my roommate's clinic. Prior to that, my vet advised the slow-kill and it worked beautifully for us. And not only my personal GP vet, but the board-certified specialty vets that I work with.
There have been LIMITED and rare cases of ivermectin breakthroughs in Louisiana I believe (at least thats what the Advantage Multi rep said when she did a presentation a few months ago) which is why I use a moxidectin based formula on my dogs.
