If you’ve ever caught your furry friend giving you those irresistible puppy eyes while you’re enjoying a hot dog topped with sauerkraut, you’ve probably wondered: can dogs actually eat this tangy fermented cabbage? The short answer is yes, but there’s more to the story than a simple green light.
Let’s dive into everything you need to know about feeding sauerkraut to your canine companion, backed by veterinary science and real nutritional facts.
What Exactly Is Sauerkraut?
Before we explore whether sauerkraut is safe for dogs, let’s understand what we’re dealing with. Sauerkraut is essentially fermented cabbage that’s been preserved through a natural process called lacto-fermentation. During this process, beneficial bacteria break down the sugars in cabbage, creating that distinctive sour taste we know and love.
According to the USDA, sauerkraut is packed with vitamins C and K, along with fiber and beneficial probiotics. These same nutrients that make it healthy for humans can also benefit our four-legged friends—with some important caveats.

Why Some Dog Owners Say “Yes!”
1. Probiotic Boost for Digestion
Sauerkraut contains live cultures — similar to those in yogurt — that promote beneficial gut bacteria. This can improve digestion and regular bowel movements when served correctly. Probiotics help prevent the overgrowth of harmful microbes in the gut.
2. Rich in Vitamins and Minerals
Fermented cabbage provides nutrients like:
- Vitamin C — supports immune health
- Vitamin K — aids blood clotting
- B vitamins — for energy
- Fiber — improves stool quality
These benefits can support your dog’s overall well-being, especially when added to a nutritionally balanced diet.
3. Low Calorie … If Kept Simple
Plain sauerkraut is low in calories. For pups on a weight-management plan, a small amount can be a flavorful treat. It’s not a replacement for their regular dog food, but it can be a healthy topper.
The Health Benefits of Sauerkraut for Dogs
Digestive Support
The probiotics found in unpasteurized sauerkraut can work wonders for your dog’s digestive system. Research published in the Journal of Animal Science shows that probiotics support healthy gut bacteria, which aids in digestion and nutrient absorption. Think of it as a natural tummy soother for your pup.
Immune System Boost
Sauerkraut contains high levels of vitamin C, which supports immune function in dogs. The fermentation process actually increases the bioavailability of nutrients, making them easier for your dog’s body to absorb and use.
Anti-inflammatory Properties
The fermented cabbage contains compounds that may help reduce inflammation. This can be particularly beneficial for older dogs dealing with joint issues or inflammatory conditions, though it shouldn’t replace veterinary-prescribed treatments.

How Much Sauerkraut Is Safe?
While there’s no single “one-size-fits-all” rule, here’s a practical guideline:
- Tiny dogs (up to 10 lbs): ½ to 1 teaspoon
- Small/medium dogs (10–30 lbs): 1–2 teaspoons
- Large dogs (>30 lbs): 1–2 tablespoons
Keep it occasional — once or twice a week at most — unless your vet suggests otherwise.
These suggestions help keep sodium intake in a safe range and let your dog enjoy the probiotics without digestive fireworks.
The Risks: Why You Need to Be Careful
Here’s where things get tricky. While plain, unpasteurized sauerkraut can be beneficial, most store-bought varieties contain ingredients that are problematic for dogs.
Sodium Overload
The biggest concern with commercial sauerkraut is its sky-high sodium content. According to veterinary nutritionists, excessive sodium can lead to dehydration, increased blood pressure, and in severe cases, sodium ion poisoning. Most store-bought sauerkraut contains 400-900mg of sodium per serving—way too much for dogs.
The Association of American Feed Control Officials (AAFCO) recommends that adult dogs consume no more than 100mg of sodium per 100 calories. A single tablespoon of regular sauerkraut could blow through that limit faster than your dog can say “woof.”
Dangerous Additives
Many commercial sauerkraut products contain ingredients that are toxic to dogs:
Onions and garlic: These are commonly added for flavor but contain compounds called thiosulfates that can damage a dog’s red blood cells, leading to anemia.
Excessive spices: Ingredients like caraway seeds aren’t necessarily toxic, but they can upset your dog’s stomach and cause digestive distress.
Artificial preservatives: Some brands include chemical preservatives that offer no nutritional benefit and may cause adverse reactions.

How to Safely Feed Sauerkraut to Your Dog
If you want to share sauerkraut with your pup, follow these veterinarian-approved guidelines:
Choose the Right Type
Look for plain, unpasteurized sauerkraut with only two ingredients: cabbage and salt. Better yet, make your own at home where you control exactly what goes in. Homemade sauerkraut allows you to reduce sodium levels and eliminate any potentially harmful additives.
Rinse It First
Before serving sauerkraut to your dog, rinse it thoroughly under cold water. This simple step removes a significant portion of the excess sodium, making it much safer for canine consumption.
Start Small
Introduce sauerkraut gradually, starting with just a teaspoon for small dogs or a tablespoon for larger breeds. Watch for any signs of digestive upset like gas, bloating, or diarrhea. Some dogs simply don’t tolerate fermented foods well, and that’s perfectly normal.
Proper Portions Matter
Even the safest sauerkraut should only be an occasional treat, not a dietary staple. Veterinarians recommend keeping sauerkraut to less than 10% of your dog’s daily food intake. For most dogs, this means a tablespoon or two, a few times per week at most.

When to Avoid Sauerkraut Completely
Certain dogs should skip sauerkraut altogether, regardless of how safe you make it:
Dogs with kidney disease: These pups need strictly controlled sodium intake, and even rinsed sauerkraut might be too much.
Dogs on sodium-restricted diets: If your vet has prescribed a low-sodium diet for any reason, sauerkraut is off the menu.
Dogs with sensitive stomachs: If your dog already experiences digestive issues, the fermented nature of sauerkraut could make things worse.
Puppies under one year: Young dogs should stick to specially formulated puppy food to ensure proper growth and development.
Making Homemade Dog-Safe Sauerkraut
Want to go the extra mile? Making dog-friendly sauerkraut at home is surprisingly easy and lets you control the sodium content.
Here’s a simple approach: Shred fresh cabbage, add just a pinch of salt (much less than traditional recipes call for), pack it tightly in a clean jar, and let it ferment at room temperature for 3-5 days. The result is a probiotic-rich treat that’s actually safe for your dog.
Just remember to store it in the refrigerator once fermented and use it within two weeks for maximum freshness and safety.
Alternative Probiotic Options for Dogs
If sauerkraut seems too risky or complicated, don’t worry. There are plenty of other ways to support your dog’s gut health:
Plain yogurt: Choose unsweetened, unflavored varieties with live active cultures. Most dogs love the taste and tolerate it well.
Probiotic supplements: Made specifically for dogs, these products deliver beneficial bacteria without any risky ingredients.
Kefir: This fermented milk drink is another probiotic powerhouse, though it should be given in small amounts.
The Bottom Line
So, can dogs eat sauerkraut? Yes, but with significant precautions. Plain, low-sodium, unpasteurized sauerkraut without any additives can offer some health benefits when given in tiny amounts. However, the risks associated with commercial sauerkraut—particularly the high sodium content and potentially toxic additives—mean you need to be extremely careful.
When in doubt, consult your veterinarian before adding any new food to your dog’s diet. Every dog is unique, with individual health needs and dietary requirements. What works perfectly for one pup might cause problems for another. You can pick name for you female dog for the training.
Remember, treats and extras should never make up more than 10% of your dog’s daily caloric intake. Their primary nutrition should always come from high-quality, complete dog food formulated to meet all their nutritional needs.
