If your Old English Sheepdog is experiencing diarrhea, gas, upset stomach, or vomiting, life can be hell for both you and your beloved pooch. 😢

Old English Sheepdogs can experience gastrointestinal issues for a myriad of reasons, but fortunately, many of these issues can be alleviated at home with a few natural remedies or supplements. However, if your Old English Sheepdog is consistently experiencing diarrhea or vomiting, make an appointment with your veterinarian right away.

Best Old English Sheepdog Upset Stomach Remedies

1. Fast Your Old English Sheepdog for 12-24 Hours

Sometimes all a dog needs is time for their gastrointestinal tract to heal and reset. Withholding food for 12 – 24 hours allows the system to flush out whatever nastiness caused the issue and reboot to a healthy state. It’s important to keep your Old English Sheepdog hydrated, even during a fast. However, do not let them drink too much at once, as this could cause vomiting or set off another bout of diarrhea.

2. Give Your Old English Sheepdog a Bland Diet for a Few Days

At the end of a fast, it’s best to slowly introduce a diet of bland, easily digestible food. Try boiled, unseasoned, skinless white meat chicken shredded over plain white rice. For dogs on grain-free diets, substitute mashed overripe banana or canned pumpkin. Feed a few spoon-fulls every 2 – 3 hours and gradually increase the quantity over a 24-hour period.

Next, begin a slow re-introduction of their normal food by serving a 75% bland/25% regular diet mix for a few meals, followed by a 50/50 mix, followed by a 75% regular/25% bland, until your dog is eating dog food exclusively again.

3. Use a Multi-Strain Probiotic for Your Old English Sheepdog’s Diarrhea or Gas

Diarrhea can disrupt the balance of bacteria in your Chihuahua’s gut, including the beneficial bacteria that support healthy digestion. A canine probiotic supplement can help maintain a balanced digestive system and support overall gut health. Pupkin™ Probiotics, Prebiotics & Postbiotics for Dogs with Pumpkin, Gut-Soothing Bone Broth & Mushrooms combines probiotics, prebiotics, and postbiotics with pumpkin to support healthy digestion and normal stool quality. It also includes gut-soothing bone broth and functional mushrooms, making it an easy-to-use option that can be added to your Chihuahua’s regular food for daily digestive support.

Using a probiotic is also helpful for reducing your Old English Sheepdog’s gas or transitioning them to a new food.

4. Give Your Old English Sheepdog a Prebiotic Supplement or Pumpkin

Canned pumpkin puree (NOT pumpkin pie filler!), slippery elm, chia seeds, and plantains are all forms of prebiotics, which are reported to offer natural GI-healing benefits. Prebiotics are a non-digestible ingredient that promotes the growth of beneficial microorganisms in the intestines. In other words, PRE-biotics are basically the food that PRO-biotics need to thrive.

Pureed pumpkin is packed with fiber, which helps to bulk up the stool. Slippery elm is said to coat and sooth mucus membranes, including the GI tract. Chia seeds are packed with fiber and absorb excess water, and plantains have antimicrobial properties. As always, consult your vet before making changes to your dog’s diet. Some high-quality supplements, like this dog prebiotic chew, already contain pumpkin in them.

5. Try Giving Your Old English Sheepdog Digestive Enzymes to Improve Digestion

Oftentimes, the cause of your Old English Sheepdog’s stomach issue may be related to incomplete digestion. Some Old English Sheepdogs have trouble digesting protein, fats, carbohydrates, or fiber. Digestive enzymes help your Old English Sheepdog break down and absorb each of these nutrients. Failure to absorb nutrients can result in bouts of runny poos, so these vital enzymes can help.

  1. Protease: Breaks down proteins into amino acids, improving digestion of meats in particular
  2. Amylase: Breaks down starches into carbohydrate molecules that your Old English Sheepdogs can digest
  3. Lipase: Breaks down fats in your Old English Sheepdog’s gut
  4. Cellulase: Breaks down fiber from plants & grains.

Any good digestive enzyme supplement for dogs should include all 4 of these enzymes.

If you were to give your Old English Sheepdog one supplement, make it this one!

Providing an all-in-one probiotic, prebiotic, & digestive enzyme supplement is the easiest way to ensure that your pup is getting the microflora they need to encourage an optimally functioning GI tract.

Additional FAQs About Your Old English Sheepdog’s Gastroenteritis, Gas, Diarrhea, Bloating, or Vomiting

1. Should I Use a Probiotic When Transitioning My Old English Sheepdog to a New Food?

Probiotics are also very useful in preventing diarrhea when transitioning your Old English Sheepdog to a new food. First, give your Old English Sheepdog a probiotic for a week or so before introducing the new food. Then slowly increase the amount of new food while continuing to feed some of the old. During this time, continue giving the probiotic until the transition to 100% of the new food is complete.

2. My Old English Sheepdog Recently Was Given an Antibiotic. Should I also Give a Probiotic?

Yes! Antibiotics destroy both good and bad bacteria in your Old English Sheepdog’s body. Giving a probiotic while taking an antibiotic will help replenish the good strains of bacteria your dog needs in their gut.

3. Can a Probiotic Reduce My Old English Sheepdog’s Gas?

Can your Old English Sheepdog’s gas clear a room? Even something as trivial as your Old English Sheepdog’s smelly farts can be helped by a good quality probiotic. It’s an easy way to improve the air quality in your home! 😜

4. What Causes Diarrhea & Vomiting in My Old English Sheepdog? 

There are many possible causes of your Old English Sheepdog’s tummy troubles:

  • Certain viruses can cause stomach upset, such as parvovirus in puppies
  • Eating a food not appropriate for dogs, especially fatty foods
  • A food allergy or intolerance
  • Swallowing a foreign non-food object
  • Sudden changes in food. Most dogs need to be transitioned slowly to a new food brand while taking a probiotic
  • Side effect of a medication, especially a new one. Antibiotics are notorious for causing diarrhea in dogs.
  • Intestinal parasites
  • Poisons or toxins
  • Pancreatitis
  • Chronic disease such as IBD  (inflammatory bowel disease)
  • Stress due to boarding at a kennel, visiting a vet, or rehoming. Dogs in shelters are particularly prone to bouts of diarrhea.

Always note the color and consistency of your Old English Sheepdog’s poop or vomit. As unpleasant as it might be, take a picture of it that you can show your veterinarian.

Helping Your Old English Sheepdog Get Back to a Happier Tummy

Digestive troubles can be uncomfortable for your Old English Sheepdog and worrying for you, but simple changes and the right digestive support may help with occasional tummy issues. Whether you try a bland diet, probiotics, pumpkin, or other gut health supplements, pay attention to how your Old English Sheepdog responds and introduce changes carefully. If diarrhea or vomiting is persistent, severe, or accompanied by other concerning symptoms, contact your veterinarian to make sure your pup gets the care they need.
