Remove only 1 chewable at a time from the foil-backed blister card and return the card to the box to protect from light.

Give the dose as soon as you remember, unless it is time for the next dose. Do not double dose.  If your dog has missed a dose please consult with your veterinarian as testing may be recommended sooner than usual.
