The dose range of ivermectin for dogs is 2.72
micrograms (mcg) per pound of body weight.
A 100 lb dog needs a 272 mcg dose of ivermectin.
The dilution I made has 1,000 mcg in each ml. So
Tyler needs about 1/3 ml.
He weighs 120 pounds times 2.72 mcg/lb = 326 mcg.
That is equivalent to the ivermectin dose in

urban civilization or search to buy this product

Ivomec and is sterile so it won't grow mold after
you set the dilution aside for next month's use.

the refrigerator with the cat & dog meds.
Using my 3 ml syringe
without a needle I transfer 9 ml of propylene glycol into the small
bottle where I first squirted the 1 ml Ivomec.
Propylene Glycol is a food additive you can purchase
at a pharmacy, feed store, or search online. It is
fairly harmless stuff.
9 ml propylene glycol + 1 ml Ivomec = a 10 ml
dilution that has, conveniently, 10 mg ivermectin in 10 ml
Hey! That is 1,000 mcg in each ml. Excellent.

20 drops = 1 ml
Since 1 ml is about 20 drops I could use an
eye dropper to measure Tyler's dose. 7 drops
would be close enough.
My 10 ml dilution = 30 monthly doses for Tyler
The 50 ml Ivomec bottle will make enough monthly
doses to last Tyler for 125 years.

Notice the 1/10 ml divisions?
My dog needs 1/3 ml - I can measure that out OK!
The dose is not very critical since
ivermectin is not very poisonous to a dog.
Nevertheless I want to only apply what is
recommended and not give my dog more than is

Tyler receives his flea & heartworm medications on
