Can Dogs Drink Buttermilk?

Share this:

Buttermilk is a fermented dairy product that has a distinctly tangy taste and creamy texture. It is a byproduct of churning cream into butter, which leaves behind the liquid residue that we know as buttermilk. While this tangy dairy drink is safe for human consumption, many dog owners wonder if dogs can have buttermilk too.

Can Dogs Drink Buttermilk

Can dogs drink buttermilk? The short answer is yes, dogs can consume small amounts of buttermilk safely and even benefit nutritionally from it. However, there are some potential risks to be aware of, and buttermilk should always be given in strict moderation.

An Overview of Buttermilk Nutrition for Dogs

To understand the implications of giving buttermilk to dogs, let’s start by looking at the nutritional profile.

Buttermilk is lower in fat and calories compared to full-fat dairy milk. One cup contains about 100 calories and 2.2 grams of fat. The fat content is considerably lower than whole milk, making buttermilk a healthier choice.

Buttermilk is a good source of protein and carbohydrates. With 8-11 grams of protein and 12 grams of carbs per cup, buttermilk provides balanced macronutrients. The whey protein is high-quality and supports muscle growth.

Buttermilk contains probiotics and prebiotics to support gut health. The live cultures act as probiotics, while compounds like lactose and oligosaccharides feed gut bacteria as prebiotics. This one-two punch promotes healthy digestion.

Buttermilk is rich in calcium, phosphorus, and vitamin B12. One cup contains about 285 mg calcium, 407 mg phosphorus, and 1.1 mcg B12. These nutrients support bone health, energy levels, and cell function.

Buttermilk provides potassium, magnesium, and riboflavin. A cup of buttermilk contains about 573 mg potassium, 27 mg magnesium, and 0.36 mg riboflavin. This nutrient profile benefits bone density, blood pressure, energy production, and antioxidant activity.

So while buttermilk is not a complete source of nutrition, it provides a powerhouse lineup of vitamins, minerals, probiotics, carbohydrates, and high-quality dairy protein. When included as part of a balanced diet, buttermilk can provide health advantages for dogs.

Potential Health Benefits of Buttermilk for Dogs

Given the nutritional profile of buttermilk, there are several potential health benefits it offers dogs when consumed in moderation:

  • Supports digestion and gut health. The live cultures and prebiotics in buttermilk promote gut bacteria and healthy digestion. Buttermilk may ease digestive issues like diarrhea or constipation.
  • Strengthens bones. The calcium and phosphorus content helps build strong bones and teeth. This is especially beneficial for puppies and senior dogs. Buttermilk may protect against bone diseases like osteoporosis.
  • Provides probiotics. The live cultures act as probiotics to support immune function and compete with pathogenic bacteria. This enhances overall health.
  • May reduce tear stains. Anecdotal evidence suggests that lactic acid in buttermilk reduces reddish tear stains in some dogs, especially breeds prone to staining.
  • Boosts energy. B vitamins like riboflavin and B12 support cellular energy production. Buttermilk provides an energy boost and fights fatigue.
  • Supports skin and coat. Healthy fats, protein, vitamins, and minerals in buttermilk nourish the skin and coat. It enhances shine and reduces dryness or flakiness.

So when included safely as part of a balanced diet, buttermilk can provide advantages ranging from probiotics to healthy skin. However, take caution with serving sizes and frequency.

Potential Risks of Buttermilk for Dogs

While the benefits are promising, there are also some potential risks to be aware of when feeding dogs buttermilk:

  • Lactose intolerance – Some dogs may experience gas, diarrhea, or vomiting from the lactose in buttermilk. Risk increases with large amounts.
  • Milk allergies – Dogs allergic to milk proteins may react with symptoms like itching, hives, diarrhea, or swelling. This is less common than intolerance.
  • High fat content – Full-fat buttermilk is high in fat. Too much may cause pancreatitis or weight gain in some dogs.
  • Overconsumption – Excessive buttermilk could cause loose stools or vomiting from too many probiotics.
  • Sodium content – Some buttermilk is high in sodium. Too much sodium can be problematic, leading to increased thirst and urination.
  • Interactions – The calcium may interfere with certain medications like cardiac glycosides or fluoroquinolones.

So while most dogs can safely handle small amounts of buttermilk, there are some risks to be aware of. Monitoring servings and your dog’s reaction is key.

How Much Buttermilk Can Dogs Have?

When feeding buttermilk to your dog, moderation is crucial. Too much can overwhelm the digestive system and lead to diarrhea or vomiting. Here are some general serving guidelines:

  • For small dogs under 20 lbs, limit buttermilk to 1-2 tablespoons per day.
  • For medium dogs 20-50 lbs, 3-4 tablespoons is a safe amount.
  • For large dogs 50-90 lbs, 6-8 tablespoons is appropriate.
  • Giant breed dogs over 90 lbs can have up to 1 cup daily.

Start slowly with small amounts like 1-2 tablespoons to see how your individual dog handles buttermilk. If stools become loose, cut back or hold off for a few days. Also, limit buttermilk treats to a few times per week rather than daily.

Pay attention to your dog’s weight and adjust quantities accordingly. Overweight dogs should get smaller servings. Also, choose low-fat varieties and avoid full-fat buttermilk.

For growing puppies, very small amounts like 1-2 teaspoons are safer since their digestive systems are more delicate. Consult your vet on proper serving sizes for puppies.

Tips for Safely Feeding Your Dog Buttermilk

When incorporating buttermilk into your dog’s diet, follow these tips for health and safety:

  • Gradually introduce buttermilk in small amounts and look for any signs of intolerance.
  • Select low-fat or non-fat buttermilk and avoid full-fat varieties high in saturated fat.
  • Check the expiration date and only feed fresh buttermilk. Soured milk can cause GI upset.
  • Make sure buttermilk is plain without added sugars, salt, flavors, thickeners, or other ingredients.
  • Serve buttermilk chilled for palatability and a refreshing treat on hot days.
  • Mix a few tablespoons of buttermilk into your dog’s regular food instead of offering it alone.
  • Monitor portion sizes carefully and stick to recommended serving guidelines based on your dog’s size.
  • Limit buttermilk treats to a few times per week rather than every day to prevent excess calories.
  • Introduce slowly and discontinue use if you notice any diarrhea, vomiting, or other intolerance signs.
  • Consult your veterinarian before feeding buttermilk to puppies, seniors, or dogs with health conditions.

Following these tips will allow you to incorporate buttermilk safely into your dog’s diet and achieve benefits without adverse effects. Monitor carefully and adjust as needed based on your individual dog.


Is it safe to give my dog buttermilk?

Yes, small amounts of buttermilk are generally safe for dogs. Start slowly and watch for any intestinal upset. Most dogs tolerate it well, but stop feeding it if diarrhea or vomiting occur.

Can puppies drink buttermilk?

You can introduce tiny amounts of buttermilk to weaned puppies over 12 weeks old. Start with just 1-2 teaspoons and increase slowly if tolerated. Their digestive systems are quite delicate, so monitor closely.

Is buttermilk good for senior dogs?

The nutrients in buttermilk can benefit senior dogs, especially the calcium for bone health. Start with very small amounts to be safe and watch for any GI issues. Check with your vet first.

Can dogs drink cultured buttermilk from stores?

Yes, dogs can consume cultured buttermilk purchased from the grocery store. Look for plain, unsweetened varieties with no salt or other additives. Check expiration dates and choose low-fat options when possible.

How much buttermilk should I give my dog?

Refer to the serving size guidelines, but in general start with 1-2 tablespoons for small dogs, 3-4 Tbsp for medium dogs, and up to 1/2 cup for very large breeds. Limit to a few times weekly.

Is buttermilk better than regular milk for dogs?

Buttermilk contains less lactose than regular milk, making it easier to digest for some lactose-intolerant dogs. The probiotics also benefit digestion. But portion control and moderation are still important.

Will buttermilk help my dog’s tear stains?

Possibly. Some dog owners report success reducing reddish tear stains by adding buttermilk to their dog’s diet or applying it topically. Discuss options with your vet if stains are significant.

Always consult your veterinarian with any concerns related to introducing new foods like buttermilk to your dog’s diet. Monitor carefully for any intolerance signals.


Can dogs drink buttermilk? In most cases, small servings of buttermilk are perfectly safe for dogs and may provide nutritional benefits.

However, buttermilk should always be fed in strict moderation due to risks like digestive upset or excessive calories.

Introduce slowly while watching for intolerance, and adjust serving sizes appropriately for your dog’s size.

As a proud cat owner, I can't imagine life without my kittens. Ever since I adopted my first cat, Fluffy, as a little girl, I've been hooked on everything cats. Now as an adult, I'm lucky enough to share my home with not one, but three lovable kitties - Fluffy, Mittens, and Tigger. They bring me amusement and comfort with their silly behavior and personalities.

Fluffy, my first cat, is now 15 years old but still acts like a playful kitten. She loves nothing more than a good game of chase the mouse toy or bat the pom poms around the house. Despite her age, she pounces around with astonishing agility. Fluffy also enjoys curling up on my lap for naptime and kneading her paws into my legs as I gently stroke her soft fur.

Mittens and Tigger are brother and sister from the same litter I adopted 5 years ago. They love to play fight, chasing each other and wrestling over toys. Mittens is the more timid one - she likes to hide under the bed when strangers come over. But once she gets comfortable, she'll come out for ear scratches. Tigger, on the other hand, is bold and adventurous. He'll explore any space and make friends with anyone. But at the end of the day, these two are the best of friends and love snuggling up for naps together.

As any cat owner knows, living with cats is a constant adventure. As cat admirer I love sharing my experiences and cat tips with others. Stay tuned for more tales, photos and insights into life with the most marvelous mammals - cats!
