What Are the Causes of Uncontrolled Diarrhea in Dogs that Lasts for Several Weeks?

Just like humans, canines can develop intestinal problems such as diarrhea. And, just like in humans, there are many variables that can cause diarrhea.



Remember that no one knows your dog like you do. If your pet has had diarrhea that lasts longer than 24 hours, or if he is exhibiting other symptoms such as vomiting, you should call your veterinarian.

  1. Change in food

    • If you have recently switched the food you feed your dog, that may be the culprit of your pet's diarrhea. If you must change your dog's food, introduce the new food slowly, by mixing a little bit in each meal of the former dog food until it is completely replaced.

      If you have not switched food, it is possible that your pet has developed a food allergy. This is rare, as food allergies typically present in other ways than diarrhea, but it is possible.

    Parasites

    • Intestinal parasites are another common cause of diarrhea, and incidentally many are tied in to your dog's diet. Be certain that your dog is not sifting through the garbage. Roundworms, hookworms and whipworms are common causes of diarrhea.

      The best way to treat diarrhea caused by parasites is to prevent them in the first place. Give your dog a monthly heart worm medication along with monthly flea and tick prevention. Make sure your dog is in clean surroundings and have your dog checked out by his veterinarian at least once a yea, perhaps more often if recommended by your vet.

    Emotional Causes

    • Any stress in a dog's life can cause a brief bout of diarrhea. Many owners of show dogs report that their pets get bouts of diarrhea during the excitement of the pageant. Typically, bouts of emotional diarrhea are short-lived. Provide your dog with plenty of water, and do your best to soothe him through the excitement.

    Cure

    • The best way to treat diarrhea is to withhold food, and provide plenty of clean, fresh water. If you can, pinpoint any changes in the dog's diet---if you've switched dog foods, then remember to slowly introduce the new dog food into your pet's diet.

      Contact your veterinarian if your dog's diarrhea is dark and/or bloody, lasts longer than 24 hours or if he is exhibiting any other symptoms such as listlessness and vomiting. Just like in humans, diarrhea is typically just an annoyance and will go away on its own. However, sometimes it is an indicator of something more serious. When in doubt, take your dog to his veterinarian.
