If Jeffers and Valley Vet are both out of horse paste, here's another source. They're a little more expensive, though.

CHEWY.COM

It's over the counter in Panama. Next time I go I may see how much I can bring back. It was 25 bucks for a box of 25

Amazon.com. Picked some up at the tack store yesterday for the ponies. Chewy.com offers free shipping for orders over $49 . Wife has been using them for pet food lately and the product arrives in short order.

Until the link to Jeffers was published, I got mine from Amazon. Not cheap. But they always had it. I like the Jeffers price much better. But even with their inflated price, a dose from Amazon is still much cheaper than a doctor copay.

If anyone is legitimately in need of ivermectin paste, my local feed mill, owned by a good friend has it. It's generic but not expired. Southwest pa, I'm sure he'd ship it if you're sincere and pay.

You could also eat your dogs hart worm treats....

Most heartworm medicine is a combination of ivermectin and pyrantel. The horse paste is all Ivermection. There's a difference. There are horse wormers with things other than Ivermectin and I really don't recommend using them.

Should of been investing in Merck&Co.INK stock.
