If the animal is still passing stool but it appears to be very firm-and the animal is otherwise healthy, i.e. normal eating and drinking habits, add 1/4 teaspoon of fiber, such as canned pumpkin or bran to the animal's diet.
If this does not work, your pet has not defecated for more than one day, or your pet appears otherwise ill, take the animal to a veterinarian. Never use commercially-sold enemas made for humans. These may be toxic and deadly to dogs and cats!
