Yes, dogs can eat sauerkraut in moderation, but it must be plain, unsalted, and free of harmful additives to benefit their digestion safely.
Understanding Sauerkraut and Its Nutritional Profile
Sauerkraut is fermented cabbage, rich in probiotics, vitamins, and minerals. It’s made by shredding cabbage and allowing it to ferment naturally with salt. This process produces beneficial bacteria known as probiotics, which support gut health. For humans, sauerkraut is a nutritional powerhouse packed with vitamin C, vitamin K, fiber, and antioxidants.
But what about dogs? Their digestive systems differ significantly from ours. While dogs are primarily carnivores, they can digest some plant-based foods and benefit from probiotics too. The question arises: can this tangy fermented veggie dish be a healthy addition to a dog’s diet?
Before feeding sauerkraut to your furry friend, it’s vital to understand its components. Commercially available sauerkraut often contains added salt or preservatives that could harm dogs. Homemade or specifically dog-safe versions without excess sodium are better options.
Health Benefits of Sauerkraut for Dogs
Fermented foods like sauerkraut offer several potential benefits for dogs:
- Probiotics Support Digestion: The live bacteria in sauerkraut promote a balanced gut microbiome. This can help improve digestion and reduce issues like diarrhea or constipation.
- Immune System Boost: A healthy gut supports immunity. Probiotics may stimulate immune cells and help fend off infections.
- Rich in Vitamins: Sauerkraut contains vitamin C and K along with fiber that supports overall health.
- Anti-inflammatory Properties: Fermented cabbage has compounds that may reduce inflammation in the digestive tract.
Still, these benefits depend heavily on the quality of the sauerkraut and the amount fed. Overfeeding or giving highly salted versions can lead to digestive upset or sodium poisoning.

The Risks of Feeding Sauerkraut to Dogs
Despite its benefits, sauerkraut isn’t without risks for dogs:
Sodium Content: Most store-bought sauerkraut has high salt levels used during fermentation and preservation. Dogs are sensitive to sodium; too much can cause increased thirst, urination issues, or even salt poisoning leading to vomiting, diarrhea, tremors, or seizures.
Additives and Spices: Some commercial brands add garlic, onions, or other spices that are toxic to dogs. Garlic and onions cause oxidative damage to red blood cells leading to anemia—a serious condition.
Bloating and Gas: Fermented foods produce gases during digestion which might cause discomfort or bloating in sensitive pups.
Poor Quality or Moldy Products: Improperly stored sauerkraut can harbor harmful bacteria or mold harmful to your dog’s health.
Toxic Ingredients Commonly Found in Sauerkraut Products:
- Garlic powder
- Onion powder/onion flakes
- Sugar or artificial sweeteners (xylitol is deadly)
- Preservatives like sulfites that may irritate digestion
Always check ingredient labels carefully before offering any fermented food.
The Right Way to Feed Sauerkraut to Your Dog Safely
If you decide to add sauerkraut as a supplement for your dog’s diet:
Select Plain Sauerkraut: Choose unseasoned varieties without added salt or spices. Ideally, make your own at home using fresh cabbage and minimal sea salt.
Dose Moderately: Start with tiny amounts (a teaspoon for small dogs) mixed into their regular food. Watch closely for any signs of upset stomach such as vomiting or diarrhea.
Avoid Daily Feeding: Use it as an occasional treat rather than a staple food item.
Avoid If Your Dog Has Certain Health Issues: Dogs with kidney problems or hypertension should avoid added sodium completely.
A Simple Recipe for Dog-Friendly Sauerkraut at Home:
- Cabbage – finely shredded (1 head)
- Celtic sea salt – just a pinch (around 1 tsp per pound of cabbage)
- A clean glass jar with lid for fermentation
Massage salt into cabbage until it releases liquid. Pack tightly into jar ensuring cabbage is submerged under its brine. Leave at room temperature for about one week until sourness develops. Store refrigerated afterward.
The Science Behind Probiotics in Dogs’ Diets
Probiotics are live microorganisms that confer health benefits when consumed adequately. In recent years, veterinary science has acknowledged their role in canine gut health:
- They promote balanced intestinal flora.
- Improve nutrient absorption.
- Reduce diarrhea caused by stress or antibiotics.
- Enhance immune responses.
Sauerkraut contains Lactobacillus species—common probiotic strains beneficial for both humans and animals.
However, not all probiotics survive canine stomach acid equally well; some commercial probiotic supplements designed specifically for pets might be more reliable than homemade fermented foods alone.
The Role of Fiber in Sauerkraut for Dogs’ Digestion
Fiber supports regular bowel movements by adding bulk and aiding water retention in stools. Sauerkraut provides insoluble fiber that helps move waste through the digestive tract efficiently while feeding beneficial gut bacteria indirectly through fermentation byproducts known as prebiotics.
This synergy between fiber and probiotics creates an ideal environment for gut health but feeding too much fiber suddenly can cause gas or loose stools—so moderation is key.
Troubleshooting: Signs Your Dog Isn’t Tolerating Sauerkraut Well
Even if you serve safe homemade sauerkraut carefully portioned out, watch your dog closely afterward:
- Bloating or excessive gas: May indicate sensitivity.
- Lethargy or weakness: Could signal salt toxicity if commercial products were used.
- Vomiting or diarrhea: Common signs of digestive upset from unfamiliar food.
- Lack of appetite after feeding: Your dog might dislike the taste or feel unwell.
If any symptoms persist beyond a day or worsen rapidly after eating sauerkraut, contact your veterinarian immediately.
