I get Ivermectin liquid, here: J R Enterprises Heartworm Prevention .com

That's a great price, much cheaper than Heartguard! Since it's sold in such large quantities (60 ml., which is a lifetime supply to treat a small Yorkie at 1/4 ml. per month), is there an expiration date on the bottle, or is ivermectin stable enough to store for the lifetime of your dog? Even if it expired after only 2 years, it's still much cheaper than Heartguard...
