Giving my "horses" the paste prophylactically and also keeping some on hand in case we get the Coof. Oops... I mean WORMS, of course. Checked on-line at numerous pet/vet med sites and Tractor Supply. All were out of stock. Found it on Amazon at double the price and limited to only one 3-pack per order.

Either people are getting wise and treating their "horses" or the DS is limiting this product to the public.

Anyone else having this problem?
