Dosages
The 1/10 cc per 10 lbs of dog is the most common dosage I've seen, but it's way stronger than Heartgard. Most dogs can handle this just fine, so I'm not saying not to do it, but if you give that dose you probably don't need any other wormers. If you are ONLY using it for heartworm prevention, and you're using other wormers for other parasites, you probably want to cut back.
Heartgard tablets for 50-100 lb dogs contain 272 mcg of Ivermectin (that's 0.272 mg). One cc of Cattle/Swine 10% Injectable Ivomec contains 10 mg (10,000 mcg). So if you use the 1/10 cc per 10 lbs of dog, you end up giving 5,000 mcg to a 50 lb dog, or about 18 times the Heartgard dosage. Now, this dosage is recommended for cows and pigs for parasite reduction, so it's probably fine in dogs, too (and lots of people do it). It's also the dosage I intend to give to my sheep. But we don't have a lot of parasite issues around here so I prefer to only treat for worms occasionally when one of my dogs shows symptoms. Since Ivomec is only used in the dogs for heartworm prevention, I can give them a MUCH lower dose.
What I do is dilute the Ivomec by taking 1 cc and mixing it in a bottle with 9 cc of propelyne glycol. This gives me a concentration of 0.1% (or 1 mg / cc, or 1000 mcg / cc). I keep this mixture in the refrigerator. Once a month, I pull out .3 cc and squirt it into a small portion of canned dog food for each dog. This gives each dog 300 mcg of Ivermectin. My dogs range in size from 45 lbs to 90 lbs. So their dosage is very close to what they'd be getting if I bought them Heartgard tablets.
One last word of caution: I know this has been said before, but it's worth repeating. NEVER give your dog Ivomec Plus. It has other medication in it which is fatally toxic to dogs. There is NO safe dosage of Ivomec Plus.
