The "for goats" stuff is nonsense. It's just a smaller bottle, labeled for goats, rather than a larger bottle labeled for cows.
Like Crisis said, the drug is Fenbendazole 10%, whether it's for cows, goats, or dogs. If you use it for dogs, do so at 1 ml per 4 lb, twice daily, for 3 days in a row.
It is a pain in the ass to use, quite frankly, and I would only use it if my dog had whips ... or maybe once in a blue moon for something different.
Unless you have a confirmed case of whips, which Pyrantel doesn't get, Pyrantel is a better choice for roundworms by far.
