I have had our dogs on liquid ivermectin for over two years. See below how our veterinarian explained how to use Ivermectin, the dosage and entire procedure.... Ivermectin Heartworm Preventative: 272 mcg per 50-100 lbs. 272 mcg = .27 mg 1% = 10 mg/ml = 1 mg/.1 ml .3 mg = .03 ml --> Monthly Dose for 50-100 lbs. Vet said to remember 3 things: 1] Ivermectin tastes very bad and the dose is so small if you try to squirt it in their mouths it can easily drool out. Squirt it onto a piece of bread and then put a little peanut butter over it and make sure the dog gets all of it. 2] It's very important to dose the proper amount. It's a VERY SMALL AMOUNT (.03 ML for 50-100 lbs.) OVERDOSING CAN KILL YOUR DOG. 3] Make sure to use IVERMECTIN 1%, not Ivomec Plus with 10% w/v clorsulon which can be FATAL to dogs. You can buy Ivermectin at the Tractor Supply Store --> http://www.mytscstore.com/ To clarify - this is dosage for Ivomec liquid "injection for cattle" (not the paste). It is not actually labeled as Ivermectin Heartworm Preventative. Vet recommended to buy the smallest box of Ivomec (i.e. 50mL) possible if you have only a few dogs as the product will expire before you use it all unless you have lots of dogs. the box I got looks like this --> <http://ivomec.us.merial.com/cowcalf/products/products_ivomec.asp> http://ivomec.us.merial.com/cowcalf/products/products_ivomec.asp Hope this helps. -Stacey ============================================================================ POST is Copyrighted 2008.
