I repeat in 10 days, then repeat again in another10 days, just to be sure. You're attempting to eradicate anynew mites that may have hatched after the first treatment because theeggs are impervious to ivermectin, as they do not suck blood like themites, themselves, do. The third treatment upon my part isjust to insure I get any and all potential stragglers.
Some breeders routinely administer treatment to their herds atscheduled intervals as a preventive measure, but I don't liketouse meds unless I have identified a bonafideproblem. Each to his own.
I have read that it is difficult to overdose a bun on Ivermectin, butMrs. Nock has related of adverse reactions within her experience and Idon't like to "second guess" Mrs. Nock's vast and accurate wealth ofknowledge. I, myself, have administered "pea sized" dollopsof Ivermectin to most of our buns at one time or another withoutanyapparent problems. Their weights ranged from 4-7 lbs.
I have also read of a breeder who, giving up her rabbit with Wry Neckfor loss, tried administering a "massive dose" of Ivermectin paste inan attempt to affect a cure. Much to her surprise, the bunsurvived and was back to normal, never suffering symptoms oftorticollis again.
