Natural Probiotics for Dogs: Advice From A Vet 

Natural probiotics for dogs are beneficial bacteria found in foods like yogurt and kefir that may help support gut health and digestion when given in small amounts. Common sources of natural probiotics for dogs include plain, unseasoned options like yogurt, kefir, cottage cheese, and some carefully prepared fermented vegetables. When suitable, these foods can be included in your dog’s routine to help support gut health, normal digestion and overall wellbeing. 

It’s important to remember that not all fermented foods are suitable for dogs. Options should always be plain and free from added salt, garlic, onion, or spices.

Every dog is different, so new foods should be introduced gradually, and it’s always a good idea to check with your veterinarian before making changes to your dog’s diet.

Natural Dog Probiotics: 5 Key Facts for Pet Parents

  1. Dog-friendly natural probiotics may help support your dog’s digestive function and stool quality when given consistently in appropriate amounts.
  2. Some suitable human foods contain natural probiotics, and there are also daily probiotic supplements formulated for dogs.
  3. Some dogs may benefit from probiotics to help bolster beneficial gut bacteria, particularly during dietary changes or if they have sensitive digestion. However, not every dog needs them, and responses can vary.
  4. When introducing probiotics, it’s important to choose dog-friendly options, start gradually, and monitor how your dog responds.
  5. If you’re unsure what’s right for your dog, your veterinarian can help guide you.

Beneficial Probiotics for Dogs 

Certain types of probiotic bacteria and yeast have been studied for their potential to support digestive function in dogs.[1] These include:

  • Lactobacillus strains (Lactobacillus acidophilus, Lactobacillus rhamnosus, and Lactobacillus planatarum)
  • Bifidobacterium strains  
  • Enterococcus faecalis 
  • Enterococcus faecium 
  • Ligilactobacillus animalis 
  • Bacillus subtilis 
  • Bacillus licheniformis 
  • Saccharomyces cerevisiae 
  • Bacillus subtilis 
  • Bacillus licheniformis 
  • Limosilactobacillus fermentum 

A healthy gut microbiome contains a wide range of bacteria, including groups such as Lactobacillus, Bifidobacterium, Enterococcus, Streptococcus, and Pediococcus. Maintaining a balanced and diverse gut environment plays an important role in digestive health and overall wellbeing.

Probiotic supplements for dogs often include strains that are commonly found in the canine digestive tract, particularly Lactobacillus and Bifidobacterium species.

PetLabCo. Probiotic Chew is formulated with spore-forming probiotic strains, including Bacillus subtilis, Bacillus coagulans, and Bacillus clausii. These strains are selected for their stability and ability to survive the digestive process, which may help them reach the gut more effectively and support digestive balance when used consistently. 

how to give probiotics to dogs
Probiotics and prebiotics can both provide beneficial support for your dog’s overall wellbeing, in different ways.

Probiotics vs. Prebiotics for Dogs 

When looking into canine probiotics, you may come across the term “prebiotics.” While they’re often mentioned together, these beneficial microorganisms support dog gut health in diverse ways, so it’s a good idea to understand the difference between prebiotics and probiotics for dogs.

  • Probiotics are live bacteria that may help support a balanced gut microbiome and normal digestion. 
  • Prebiotics are types of non-digestible fiber that act as a food source for beneficial bacteria.
  • Both probiotics and prebiotics can support gut health and may help support digestive comfort. Probiotics introduce beneficial bacteria, while prebiotics help support the growth and activity of those bacteria over time.
  • Some natural foods may provide sources of probiotics or prebiotics, but not all are suitable for dogs. 
  • It’s important to choose dog-friendly options, introduce new foods gradually, and check with your veterinarian before making changes to your pup’s diet.
  • Research into natural food sources of probiotics for dogs is still developing, and clear feeding guidelines are not always established. For this reason, consistency, appropriate portion sizes, and veterinary guidance are important.

9 Foods With Probiotics For Dogs

The following dog-friendly foods may contain probiotic bacteria that can help support your dog’s digestive function and overall wellbeing when given in small, appropriate amounts.

  1. Kefir: Kefir is a fermented milk drink that contains a variety of beneficial microorganisms. If feeding kefir, start with a very small amount (such as ¼ teaspoon) and increase gradually if well tolerated. Dogs with dairy sensitivities should avoid kefir. Always check with your veterinarian before feeding, especially if your dog is on medication. 
  2. Fermented Blueberries: Fermented blueberries may contain Lactobacillus. If offering these, start with a very small amount and monitor your dog’s response. Because preparation methods can vary, it’s best to seek guidance from your veterinarian before feeding fermented foods.
  3. Cottage Cheese: Cottage cheese may contain Lactobacillus acidophilus. It can be offered in small amounts if your dog tolerates dairy. Avoid if your dog is sensitive to dairy, and introduce gradually to assess tolerance.
  4. Fermented Bananas: Fermented bananas may contain gut-friendly bacteria, depending on how they are prepared. As with all fermented foods, start with a very small amount and monitor your dog’s response. 
  5. Fermented Carrots or Broccoli: Offer only small amounts of suitable fermented vegetables to begin with and ensure they are plain and unseasoned.
  6. Pickles: Pickles may be suitable if naturally fermented. However, most pickles are high in sodium or contain ingredients like garlic or spices, which are not suitable for dogs. If used at all, only offer plain, unseasoned, low-salt varieties in very small amounts and infrequently.
  7. Sauerkraut: Sauerkraut may contain Lactobacillus species. If feeding, choose plain, unseasoned versions without added salt or spices, and offer only small amounts. 
  8. Green Tripe: Green tripe (the stomach lining of ruminant animals) naturally contains good bacteria. It can be included in some dogs’ diets, but it is a raw product and should be handled carefully. Always consult your veterinarian before feeding raw ingredients.
  9. Yogurt: Plain, unsweetened yogurt contains Lactobacillus. Greek yogurt is often preferred if you will be feeding yogurt to your dog due to its lower lactose content. Avoid flavored or sweetened varieties, and do not feed if your dog is sensitive to dairy.

Important Advice on Feeding Natural Probiotics To Dogs

  • Not all fermented foods are suitable for dogs – always choose plain, unseasoned options
  • Introduce new foods gradually and monitor your dog’s response
  • Portion sizes are not standardised and may vary between dogs
  • Some dogs may not tolerate dairy or fermented foods
  • Always consult your veterinarian before introducing new foods

7 Sources of Natural Prebiotics for Dogs 

Prebiotics are types of non-digestible fiber that help feed beneficial bacteria in your dog’s gut. When included as part of a balanced diet, they may help support digestive health and overall gut balance.

Common dog-friendly sources of natural prebiotics include:

  • Pumpkin
  • Sweet potato
  • Oatmeal
  • Carrots
  • Broccoli
  • Blueberries
  • Bananas

When introducing prebiotic-rich foods, it’s important to start with small portions and increase gradually. Some dogs may experience temporary digestive changes, such as gas or softer stools, as their system adjusts.

As always, choose dog-friendly options, introduce new foods slowly, and check with your veterinarian before making changes to your dog’s diet.

Precautions When Feeding Dogs Foods with Natural Probiotics 

Before introducing natural probiotics, it’s always a good idea to check with your veterinarian – especially if your dog is experiencing any digestive discomfort or is taking medication.

Here are some key things to keep in mind:

  • Introduce foods gradually: Any new food can cause temporary digestive changes. Start with small amounts and increase slowly over several days while monitoring your dog’s response. Some dogs may experience mild gas, bloating, or softer stools as their system adjusts.
  • Watch portion sizes: Foods given as treats or additions to meals, including natural probiotic sources, should make up no more than 10% of your dog’s daily calorie intake. Adding extra foods without adjusting their main diet may contribute to weight gain over time.
  • Consider sensitivities and allergies: If your dog has known food sensitivities or allergies, some probiotic foods (particularly dairy or certain vegetables) may not be suitable. Always check before introducing new ingredients.
  • Choose dog-friendly ingredients: Not all fermented or “healthy” foods are suitable for dogs. Avoid options with added salt, garlic, onion, spices, or artificial sweeteners like xylitol, which can be harmful.
  • Be aware of limited research: Research into natural dog probiotics is still developing. Feeding guidelines are not always clearly established, and responses can vary between dogs.
  • Account for underlying health conditions: Some probiotic foods, particularly fermented options, may be higher in sodium or not suitable for dogs with certain health conditions. If your dog has ongoing digestive or medical concerns, your veterinarian can help guide appropriate choices.

Can I Make Homemade Probiotics for Dogs? 

You should always consult with a veterinarian before making homemade probiotics for dogs. Adding any new foods can easily throw off the balance of your dog’s diet and contribute to obesity. 

However, you can mix and match dog-safe probiotic foods to give as treats in moderation. Just make sure to do this under guidance from your veterinarian. 

Keep in mind that homemade recipes featuring foods with probiotics will have a shelf life. Pet parents should store any homemade treats or food appropriately and be sure to avoid giving dogs foods past their expiration date.  

Example: Frozen Probiotic Dog Treat

A simple frozen treat can combine ingredients that may help support digestive health when given occasionally:

Ingredients:

  • 2 cups plain, unsweetened Greek yogurt
  • ¼ cup plain peanut butter (xylitol-free)
  • ¼ cup pumpkin puree

Instructions:
Mix the ingredients together, portion into an ice cube tray or mould, and freeze. Serve in small amounts as an occasional treat.rve up probiotic treats to your dog! 

Important Considerations

  • Introduce any new foods gradually and monitor your dog’s response
  • Treats, including homemade options, should make up no more than 10% of daily calorie intake
  • Not all dogs tolerate dairy or certain ingredients
  • Recipes not guided by a veterinarian may not be nutritionally balanced

If you’re unsure whether homemade probiotics are suitable for your dog, your veterinarian can help guide you based on their individual needs.

Foods With Probiotics Vs. Probiotic Supplements for Dogs 

Both natural probiotics and probiotic supplements can play a role in supporting your dog’s digestive health, but they differ in how they are used and what they provide.

Quick Comparison: Natural Probiotics vs Supplements for Dogs

ConsiderationNatural probiotics for dogsProbiotic supplements for dogs
Research and formulationNatural probiotics, while commonly used, are less consistently studied in dogs.Probiotic supplements for dogs are typically formulated specifically for canine use, and some have been studied for their role in supporting digestive health.
Consistency and CFU levelsNatural food sources can contain gut-friendly bacteria, but the amount and type can vary depending on how the food is prepared and stored.Probiotic supplements usually provide a measured amount of live bacteria, often expressed as colony-forming units (CFUs). This allows for more consistent dosing.
Calories and portion controlDog-friendly probiotic foods contribute additional calories. Feeding larger amounts to match supplement levels may not be practical and could affect your dog’s overall diet balance.Probiotic supplements are generally low in calories and can be added without significantly changing your dog’s daily intake.
Suitability for dogsProbiotic foods may still be suitable in small amounts, but not all options are appropriate for every dog.Supplements are designed with dogs in mind, including strain selection and dosage guidance. 
Variety and individual responseDifferent natural probiotics may suit different dogs, and responses can vary.Supplements can vary in their composition. Different strains, formats, and ingredients may suit different dogs, and responses can vary.
Overall approachProbiotic foods can be included in moderation as part of your dog’s balanced diet. They should be factored into overall calorie intake to avoid overfeeding.When used as part of a consistent routine, some pet parents choose supplements for convenience. Dog-specific probiotic supplements may offer more consistency in formulation and dosing. 

Dog-friendly natural probiotics and dog-specific probiotic supplements can both help support your pup’s digestive health when used appropriately. The best approach depends on individual needs and should be guided by your veterinarian.

Other Sources of Probiotics for Dogs

In addition to natural food sources, there are several other ways to give dog probiotics, including soft chews, powders, capsules, and specially formulated dog foods.

When choosing a probiotic, it’s important to look for products designed specifically for dogs. While some human foods like yogurt or kefir contain beneficial bacteria, dog-specific probiotics are formulated with strains and dosages intended for canine digestive systems.

Dog probiotics are generally used to help support a balanced gut environment and normal digestion when given consistently. Different formats may suit different dogs, depending on their preferences and routine

Probiotic Soft Chews for Dogs

Soft chews are a popular option because they are easy to give and can fit easily into a daily routine.

Products like PetLabCo. Probiotic Chew are formulated with a blend of probiotics, prebiotics, and postbiotics, and are designed to help support digestive balance and normal stool quality when used consistently. Some pet parents choose this format for convenience and ease of use.  PetLabCo. also has an Allergy & Immune Probiotic Chew, which may be a good alternative to natural probiotics for dogs with seasonal allergies. 

Probiotic Powders and Capsules

Probiotic powders can be sprinkled over your dog’s food, while capsules may be given whole or opened and mixed into meals, depending on the product instructions.

These formats can offer flexibility, although some dogs may be more selective with food that has been altered. It’s always best to follow the product’s guidance and monitor your dog’s response.

Probiotic Dog Food

Some dog foods include added probiotics or prebiotics as part of their formulation. If you’re considering switching to one of these options, your veterinarian can help determine whether it’s a suitable choice for your dog.

Dog probiotics can be given in a variety of formats, from natural foods to supplements and functional dog foods. The right option often depends on your dog’s individual needs, preferences, and routine. For guidance on what may work best for your dog, your veterinarian can help you make an informed choice.
