I've searched here and elsewhere doing a lot of reading on using Ivermectin labeled for cattle as a heartworm prevenitive in dogs. After wading through a lot of information (some good, some bad) from Vets, chemists and pharmacists I would appreciate your input as to whether or not I have come to a correct conclusion regarding the particulars and details.

IVERMECTIN USE IN DOGS

1% Ivomec Injectable (10 mg/ml) (NOT Ivomec Plus which is also labeled for Fluke worms).
1ml mixed with 9ml propylene glycol makes 10 mg in 10 ml (1,000 mcg/1ml)

Durvet Pour On is 5 mg/ml (500 mcg/1ml). 2ml mixed with 8ml propylene glycol makes 10 mg in 10 ml (1,000 mcg/1ml)

Heartgard dose is 0.003-0.006 mg/kg (3-6 mcg/kg)
High dose of 6 mcg/kg equals 2.72 mcg/pound.

Dosing formula: Weight of dog in pounds multiplied by 2.72 then divided by 1,000 equals the dose in mililiters.

Reference chart:
60 lb. = 0.16 ml of solution
65 lb. = 0.18 ml of solution
70 lb, = 0.19 ml of solution
75 lb. = 0.20 ml of solution
80 lb. = 0.22 ml of solution
85 lb. = 0.23 ml of solution
90 lb. = 0.24 ml of solution
95 lb. = 0.26 ml of solution
100 lb = 0.27 ml of solution

I'm sorry, but the public board can't recommend off-label use of a med, or prescribe at all.

I've seen public boards giving advice that was actually off by a whole decimal place, and that failed to mention breeds not to give it to.
