When fed to dogs or cats, Coproban will create an unpleasant taste in that animal's feces, discouraging other pets from eating the stool. Roast beef flavored soft chews are individually blister packed for convenience. Feed dogs and cats under 40 lbs. 1/2 soft chew with each meal. Over 40 lbs., 1 soft chew with each meal. Add 1/2 soft chew for every 40 lbs. thereafter.
