Can Dogs Eat Kefir: A Healthy Addition to Your Dog’s Diet

When it comes to choosing the right kind of food for our furry friends, we often come across a plethora of information. One food item that has gained popularity in recent years is kefir. But is it safe for dogs? In this article, we’ll dive into the topic of whether or not dogs can eat kefir, discuss its benefits, and provide tips on how to include this probiotic-rich superfood in your dog’s diet.

The Benefits of Kefir for Dogs

Supports Digestive Health

Kefir contains a wide variety of beneficial bacteria and yeast, also known as probiotics. These probiotics can help restore the balance of good bacteria in your dog’s digestive system, promoting overall gut health. This can help reduce the symptoms and frequency of gastrointestinal issues such as diarrhea, constipation, and gas.

Boosts Immune System

A healthy, well-functioning immune system is essential for your dog to stay active and happy. Kefir is rich in vitamins, minerals, and essential amino acids that support immune health, such as vitamin D and K, and calcium. It also contains antioxidants that can help fight off diseases and infections.

Improves Allergies and Skin Condition

The probiotics in kefir can have a positive impact on a dog’s allergy or skin issues. By improving the dog’s immune response, kefir can help reduce inflammation and, in turn, support the healing of skin conditions, such as atopic dermatitis or hot spots.

How to Include Kefir in Your Dog’s Diet

Introducing kefir as a supplement to your dog’s diet can be simple and fun. Follow these guidelines to make it a smooth integration:

Start Slowly

When first adding kefir to your dog’s food, start with small amounts to avoid overwhelming their digestive system. Gradually increase the amount over the course of a few days or a week, until you reach the recommended portion for your dog’s size and weight.

Choose Unsweetened, Unflavored Kefir

Not all kefir varieties are suitable for dogs. It’s important to select kefir that is unsweetened and unflavored since added sugars, flavors, or artificial additives may be harmful to your dog. Look for kefir with minimal ingredients, preferably containing only milk and live cultures.

Mix Kefir with Your Dog’s Food

A delicious and easy way to introduce kefir to your dog’s diet is by mixing it with their regular dog food. The creamy texture of kefir works well with both wet and dry food, making it a versatile addition to mealtime. You can also freeze kefir in ice cube trays for a cool, refreshing treat during hot summer days.

Kefir Dosage for Dogs

The appropriate kefir dosage for your dog will depend on their size and weight. As a general guideline, follow these recommended daily amounts:

  • Small dogs (up to 20 pounds): 1 teaspoon to 1 tablespoon
  • Medium dogs (20-50 pounds): 1 to 2 tablespoons
  • Large dogs (50+ pounds): 2 to 4 tablespoons

Always consult with your veterinarian before adding any new supplements to your dog’s diet, including kefir. They will be able to advise you on the best course of action based on your dog’s individual needs and medical history.


Including kefir in your dog’s diet can provide numerous health benefits, such as improved digestion, increased immune support, and better skin health. Start by introducing kefir slowly and in small amounts, and make sure to choose unsweetened, unflavored kefir. Mix it with your dog’s food or serve it as a frozen treat to make it a fun and delicious addition to their daily routine.

Common Concerns and Precautions When Feeding Kefir to Dogs

Lactose Intolerance

One concern dog owners may have is that their dogs are lactose intolerant. While it is true that some dogs have difficulty digesting lactose, the fermentation process of kefir significantly reduces the lactose content, making it more tolerable for lactose-sensitive dogs. However, if your dog has a severe lactose intolerance or is allergic to dairy products, it is best to consult your veterinarian before introducing kefir into their diet.

Caloric Intake

Adding kefir to your dog’s diet can contribute additional calories which, when not accounted for, could lead to weight gain. When incorporating kefir, adjust the portion sizes of your dog’s meals accordingly to maintain a healthy weight and avoid overfeeding.

Homemade Kefir: A DIY Option for Your Dog

If you prefer to have complete control over what goes into your dog’s food, making your own kefir at home can be a rewarding and cost-effective option. Here’s a simple guide to get started:

Ingredients and Supplies

  • Milk – For a more dog-friendly option, opt for goat’s milk which is easier to digest.
  • Kefir grains – Available online or at local health food stores.
  • Glass jar with lid – For fermenting the kefir mixture.
  • Plastic strainer and spoon – Use non-metal utensils to avoid reacting with the kefir grains.


  1. Place 1-2 tablespoons of kefir grains in a clean glass jar.
  2. Add 2 cups of milk to the jar, leaving at least an inch of space from the top for expansion.
  3. Cover the jar with a lid or cheesecloth secured with a rubber band.
  4. Leave the jar at room temperature (68-78°F) away from direct sunlight to ferment for 24-48 hours.
  5. Once the kefir has thickened, gently stir the mixture and strain the kefir grains from the liquid using a plastic strainer, collecting the kefir in a separate container.
  6. Place the kefir grains back in the glass jar and add fresh milk, repeating the process to make more kefir.
  7. Store the finished kefir in the refrigerator for up to two weeks.

Remember that, as with store-bought kefir, it’s essential to introduce homemade kefir to your dog gradually, and in small amounts to avoid digestive issues.

Kefir Alternatives for Dogs

If you’re looking for other probiotic alternatives to promote your dog’s digestive health, consider these options:

Probiotic Supplements

There are various probiotic supplements specially formulated for dogs, available in powders, capsules, or chewable forms. Consult your veterinarian for a suitable recommendation based on your dog’s individual needs.


Plain, unsweetened, and unflavored yogurt is another good source of probiotics for dogs. Just like kefir, start with small amounts and gradually work your way up. Keep in mind that yogurt typically contains higher levels of lactose compared to kefir, so be cautious if your dog has lactose intolerance.

Fermented Vegetables

Fermented vegetables like sauerkraut, kimchi, or pickles can be a source of probiotics for your dog. Make sure to choose options without added sugars, spices, or artificial preservatives that can be harmful to your dog. Note that some dogs may not be fond of the sour taste – always introduce new foods slowly and observe your dog’s reaction.

By doing thorough research and consulting with your veterinarian, you can confidently make the best decisions about incorporating probiotics like kefir into your dog’s diet for optimal health and well-being.
