i'm not a vet but was a vet tech for 8 years, the ivermectin i use is the swine/cattle 1% injectable, the dose for deworming a dog is 0.10ml per 10 lbs, i give it orally, i was told never go above 0.80ml even for a big dog, no collie breeds because it can cross the blood brain barrier in those breeds, notice the decimal points, overdosing is easy and can cause liver failure and neurological problems so be very careful, never use the horse paste, it's too concentrated and cannot be dosed properly, hope this helps
