How to Administer Kaopectate to a Dog

Step 1

Gather all the necessary items on a table. Choose a quiet area of your home and remain calm so as not to upset the dog.


Step 2

Weigh your dog and consult with your vet to determine the correct dosage. The dose for dogs is 0.5 to 1.5 ml per pound per day, according to Dr. Mark Papich. This should amount to approximately 2 teaspoons (10 ml) per 10 pounds of weight per day. This total daily dose should be divided into two to four doses as necessary.


Step 3

Fill the oral syringe with the correct amount of Kaopectate. Keep in mind that one teaspoon equals 5 cc or 5 ml.


Step 4

Administer the Kaopectate medication slowly to prevent choking or vomiting. Place the oral syringe in the pocket formed between the dog's cheek and back teeth.


Step 5

Praise your dog for cooperating and clean up any messes with the paper towels. Monitor your dog and consult with your vet if the diarrhea does not subside within 48 hours or if the dog is not active and alert.
