Can Dogs Eat Sauerkraut

Sauerkraut is finely shredded and fermented cabbage that offers a tangy, salty flavor. It’s a popular side dish in many cuisines and is most commonly associated with German and Eastern European food.

Sauerkraut is not inherently dangerous or toxic to dogs when eaten in small amounts. The main ingredients in sauerkraut are cabbage, salt, and water – all of which are safe for dogs. In fact, the live cultures formed through the fermentation process can provide some great probiotic benefits when served occasionally as a dietary supplement.

Of course, moderation and proper preparation is key when feeding sauerkraut to prevent digestive issues. Later in this article, I’ll provide my expert guidelines on how much sauerkraut dogs can eat, serving suggestions, and signs to watch out for if your dog eats too much.


What Are The Nutritional Benefits Of Sauerkraut For Dogs?

Here are some of the top nutrients and compounds dogs can gain from sauerkraut when served occasionally in moderation:

Probiotics – The live bacterial cultures create probiotics that support healthy dog digestion, improve immunity, and may help conditions like diarrhea or irritable bowel disease. Lactobacillus is one of the main “good bacteria.”

Prebiotics – Sauerkraut contains oligosaccharides which act as fuel for probiotics to thrive. The combination of prebiotics and probiotics make sauerkraut a prebiotic.

Vitamin C – Raw cabbage contains this powerful antioxidant vitamin. Vitamin C boosts dog immunity, wound healing, skin/coat health, joints, and fights disease.

Vitamin K – Necessary for proper blood clotting and bone metabolism in dogs. Deficiency can cause bleeding disorders.

Vitamin B6 – Aids dog metabolism, brain development, immune health, digestion, and nutrient absorption.

Fiber – Both the cabbage and live cultures provide insoluble fiber that promotes regularity and digestive health in dogs.

Minerals – Sauerkraut contains small amounts of beneficial minerals like iron, calcium, magnesium, and potassium for dogs. Adds variety.

As you can see, sauerkraut offers a nutritious boost to a balanced dog diet when fed properly!

Health Benefits of Sauerkraut for Dogs

In addition to nutritional value, here are some of the top ways sauerkraut can benefit dog health:

Supports digestion – The natural probiotics help regulate gut bacteria and may ease digestive issues like diarrhea, constipation, IBD, colitis, gas, and vomiting if fed routinely. Especially helpful for dogs on antibiotics.

Bolsters immunity – Probiotics support healthy immune function in dogs and may help fight disease and infection. Benefits skin health and allergies too.

Aids urinary tract health – The vitamin C content makes sauerkraut a gentle diuretic to help flush bacteria from dog urinary tracts and prevent infection. Increase hydration.

Fights yeast overgrowth – Probiotics create beneficial bacteria to crowd out harmful yeasts that can cause ear infections, skin issues, and other problems in dogs.

Supports heart health – Antioxidants and vitamins in sauerkraut promote dog cardiovascular function and may lower risk of heart disease.

Provides antioxidants – Vitamins C and K have antioxidant properties that fight cell damage from free radicals, prevent disease, and slow aging.

When fed properly, sauerkraut can be a healthy supplemental food for dogs thanks to its unique nutritional composition and probiotic boost!

What Are The Ingredients In Sauerkraut?

Traditional sauerkraut has just 3 main ingredients:

Cabbage – Provides essential vitamins, minerals, antioxidants, and fiber. Choose fresh organic cabbage for best nutrition.

Salt – Sodium alters cabbage texture, draws out moisture, and prevents harmful bacteria growth during fermentation. Use non-iodized sea salt or kosher salt.

Water – The cabbage releases liquid that creates the brine for lactic acid bacteria to ferment in. Filtered water keeps sauerkraut crunchy.

Some sauerkraut may also contain:

Caraway or juniper seeds – Added for flavor. Should not cause issues for dogs in small amounts but avoid if allergies are a concern.

SpicesGarlic, onion, black pepper – heavily seasoned sauerkraut varieties may irritate some dogs’ stomachs. Go plain.

Preservatives – Canned sauerkraut may contain preservatives like sorbic acid. Fine in moderation but best to limit.

When buying sauerkraut for dogs, go for simple, all-natural types without heavy add-ins

Can Dogs Eat Sauerkraut With Caraway Seeds?

Some types of sauerkraut contain caraway seeds, a spice added for extra flavor. The question is, are caraway seeds safe for dogs to eat as well?

The answer is yes – the small amounts of caraway added to sauerkraut should not pose a toxicity risk to dogs when consumed in moderation. In fact, caraway seeds may provide antioxidants and fiber.

However, dogs that eat very large amounts of caraway seeds could potentially get digestive upset or allergic reactions in rare cases. To be safe, look for sauerkraut without caraway seeds if your dog has a sensitive stomach.

Can Dogs Eat Canned Sauerkraut?

Canned sauerkraut you find in supermarkets is typically pasteurized, which kills off most of the beneficial live cultures produced through fermentation. While canned sauerkraut is safe for dogs, it does not provide the same probiotic benefits as raw sauerkraut.

Canned varieties may also have added preservatives like sorbic acid which are harmless in small amounts but best limited in dog diets. If feeding canned sauerkraut, moderation is key and raw, unprocessed versions are ideal.

Can Dogs Eat Cooked Sauerkraut?

Lightly cooked or steamed sauerkraut is fine for dogs to eat, as long as salt content is limited. However, cooking sauerkraut destroys many of the healthy enzymes and probiotics that make it beneficial.

Raw, unheated sauerkraut has the most nutritional value and live cultures intact. If you want to warm it up before serving, do so gently. Never let sauerkraut sit out at room temperature for long periods, as bacteria can quickly grow.

Can Dogs Eat Uncooked Sauerkraut?

Raw, uncooked sauerkraut is the best way to feed dogs from a nutritional standpoint.

The raw cabbage contains vitamins C, K, and B6, while the fermentation process creates natural probiotics and prebiotics. These living cultures aid dog digestion and immunity.

For safety, be sure to buy refrigerated sauerkraut produced in sanitary conditions, not jarred shelf-stable varieties. Feed raw sauerkraut freshly refrigerated, in small portion sizes.

The only risk of raw sauerkraut is the high sodium content. Watch your dog’s salt intake from other sources if feeding raw sauerkraut frequently.

Is Warm Homemade Sauerkraut Good For Dogs?

Cooked and freshly homemade sauerkraut is reasonably safe for dogs to consume, though raw retains more nutrition. The fermentation and canning process is key for safety.

If you want to make your own dog-friendly sauerkraut at home, be sure to:

  • Use recently harvested, organic cabbage – old cabbage has lower vitamin content
  • Culture the sauerkraut properly for 4+ weeks at cool room temperature
  • Monitor for signs of mold, fungus, or other contamination
  • Refrigerate immediately after fermenting, and discard any batches with odd smells or appearance
  • Add no onions, garlic, spices, or seasonings dogs shouldn’t consume
  • Gently steam or warm sauerkraut before serving, don’t boil or overcook

With the proper preparation, homemade sauerkraut, in moderation, can be a nutritious occasional treat for dogs! Just be vigilant for signs of stomach upset or intolerance.

Is Pork And Sauerkraut Okay For Your Pup?

Traditional German cuisine often pairs sauerkraut with sausage or pork. However, pork should always be avoided when feeding sauerkraut to dogs.

Dogs struggle to digest fatty meats like pork, bacon, or sausage. These foods can cause severe pancreatitis in dogs, a dangerous inflammatory condition.

Onions and garlic in sausage seasonings are also toxic to dogs in large amounts. Never purposefully feed dogs sausage or other preserved pork meats.

Stick to dog-safe meat like cooked chicken or lean beef if mixing a bit of meat into sauerkraut for dogs. Avoid fatty cuts and heavily seasoned meats.

How Much Sauerkraut Can Dogs Eat?

When introducing a new food, moderation is always wise. Here are my portion guidelines based on dog size:

  • Small dogs – 1-2 tablespoons sauerkraut 1-2x a week
  • Medium dogs – 3-4 tablespoons 1-2x a week
  • Large dogs – Up to 1/4 cup sauerkraut 1-2x a week.

I suggest serving sauerkraut as no more than 10% of your dog’s total weekly diet. Too much can lead to gas, diarrhea, and sodium overload.

If your dog has stomach issues, start with just a teaspoon and increase slowly over 2 weeks while monitoring reactions. Some dogs may not tolerate even small amounts.

How Should Sauerkraut Be Served for Dogs?

For safety and digestion, I recommend:

  • Serving sauerkraut plain without added spices, oils, salt, or meat
  • At room temperature or slightly warmed, not piping hot
  • Mixed into their regular dog food, not alone as a full meal
  • In a dog bowl, not shared human dishes

Avoid letting dogs eat directly from the sauerkraut jar, as bacteria transfer could lead to illness. Wash dog bowls promptly after feeding sauerkraut.

If your dog doesn’t seem to like the taste of sauerkraut, reduce portions to just a spoonful and mix thoroughly into their kibble. The other flavors should mask sauerkraut flavor.

Is Sauerkraut Ever Bad for Dogs?

While sauerkraut provides benefits, it does carry some risks for dogs prone to:

Sodium sensitivity – Limit if your dog has heart/kidney disease. Can cause or worsen hypertension.

Allergies – Dogs allergic to cabbage may react to sauerkraut with upset stomach, skin irritations, or anaphylaxis in rare cases.

Urinary crystals/stones – Oxalates in cabbage may worsen calcium oxalate bladder stones. Consult your vet.

Thyroid issues – Very high cabbage intake could potentially impact thyroid function long-term.

If your dog exhibits signs like vomiting, diarrhea, itching, hives, or trouble breathing after eating sauerkraut, discontinue feeding and see your vet.

What Are Sauerkraut Probiotics and How Do They Improve a Dog’s Health?

The live cultures that form in sauerkraut through fermentation are called probiotics. These “good bacteria” like Lactobacillus provide a range of health benefits:

  • Colonize the GI tract to crowd out “bad” bacteria and yeast overgrowth
  • Reinforce tight junctions in the dog gut lining, preventing leaky gut syndrome
  • Reduce gut inflammation and irritation that can cause diarrhea or IBD
  • Ramp up immune response by increasing antibodies and white blood cell production
  • Synthesize important vitamins like K, B12, and folate
  • Improve nutrient absorption from food
  • Modulate key hormones related to appetite, obesity, mood, and stress response
  • May guard against some chronic diseases by lowering cholesterol and blood pressure

By bolstering populations of healthy bacteria, sauerkraut probiotics help create overall balance and optimal function of the canine GI system. Make sure to introduce sauerkraut slowly and watch for added gas or diarrhea.

To safely incorporate sauerkraut into your dog’s diet, I suggest:

  • Consult your vet first, especially if your dog has health conditions
  • Select raw, organic sauerkraut with no additives
  • Serve plain sauerkraut, no seasonings or salt added
  • Introduce slowly in tiny amounts mixed into meals
  • Monitor for signs of intolerance like vomiting or diarrhea
  • Reduce portion size if gas, stomach gurgling, or excess thirst occurs
  • Avoid giving with high sodium foods like deli meats or canned fish
  • Refrigerate leftovers promptly and discard if mold develops
  • Limit to a few times a week for occasional nutritional boost

With proper introduction and moderation, sauerkraut can offer a tasty and healthy supplemental food for dogs to enjoy! Just be watchful of reactions and adjust as needed to keep your dog happy and comfortable.
