Another good book....
is titled The Reptile's Clinician Handbook.
It has a tom of info on doseages and what to use for what along with a ton of other ropics including wounds and ect. Also has a lot of stuff you probably wont use like anistesia...and vet stuff. But fun to learn anyhow.
Also, Ive only seen 1 strength of Ivomec.....somthing like 10,000 micrograms per ML or 10 mg's per ML. Same stuff used in cattle, horses and swine.
Don't waste your time.....EMBRACE IT!!
And then you'll know yourself....
