Instructions
Provide plenty of fresh water for your large dog. Encourage your dog to drink frequently throughout the day to avoid dehydration.
Contact your veterinarian if the diarrhea lasts for more than one day, or if your dog experiences fever, lethargy, vomiting or unexplained weight loss. Report dark-colored or bloody stools to your veterinarian immediately.
Support your dog at the veterinarian's office. Your dog will receive diagnostic tests (blood tests, stool sampling, ultrasound and cultures) to determine the cause of diarrhea.
Follow the at-home care or treatment plan prescribed by the veterinarian. Your dog may require medication if something like a parasite is causing the issue, a diet change or special care.
How to Stop Diarrhea in a Large Dog
A dog of any size or breed can experience occasional or chronic diarrhea (loose, watery bowel movements) when illness, stress or a change in diet occurs. A single episode of diarrhea is usually nothing to worry about, but if your large dog has diarrhea lasting for more than one day, take your dog to see a veterinarian. A veterinarian will diagnose and treat your dog for any underlying health problems that may be causing the diarrhea. Chronic diarrhea is a serious health problem and should be treated quickly because it can lead to dehydration if left untreated.
