A doctor gave me that for early treatment of cancer, too. I still have a bottle, I will remember for the dog if need be.
An even better deworming trick for a pet or human is a little diatomacious earth sprinkled on the food. Don't get the kind for pools and spas, get the garden kind. Works for fire ants too.
(anybody notice a recurring theme of fire ant cures from me? they are a plague of Biblical proportions!)
