Commercial synthetic dog wormers can have undesirable side effects, and only work against certain types of worms, with no effect at all on protozoa and some other harmful parasites. In contrast, #13 Herbal Wormer naturally supports your dog’s natural defenses against worms, because when it’s operating correctly, that defense system is enough to destroy or expel unwanted parasites.
This formula is not intended to replace heartworm preventative medications. Even animals medicated with such preventatives should use #13 Herbal Wormer to aid the body in natural deworming defenses and resistance of protozoa.
 
Barberry and Cascara help expel parasites and protect the digestive tract.
Garlic and Milk Thistle support antibacterial and liver health.
Dog owners report fewer worm infestations and better overall health.
