Can Dogs Drink Buttermilk? Is Buttermilk Safe for Dogs?
Published: 20 Mar 2025
Hello, Dog Lovers!
Imagine you’re whipping up a batch of pancakes and have some leftover buttermilk. Your canine companion is gazing at you with those irresistible puppy-dog eyes. But before you share, you might be wondering, ‘Can dogs drink buttermilk?’ The answer is it depends.
Some dogs can handle dairy without issues, while others struggle with lactose intolerance. In this guide, we’ll explore whether buttermilk is safe for dogs—considering both lactose-tolerant and lactose-intolerant pups—its potential effects and why you should be cautious. Plus, we’ll share safer treat alternatives for your furry friend.
Dr. Musky Abal, a veterinarian and canine nutrition expert, will discuss the details of both types of dogs to help you decide what’s best for your furry friend’s stomach.
All dairy products contain lactose, a natural sugar that requires the enzyme lactase for digestion. Dogs vary in their ability to process lactose based on their lactase levels. Lactose-tolerant dogs produce enough lactase to break down lactose easily, allowing them to consume dairy, like buttermilk, without issues. However, lactose-intolerant dogs lack sufficient lactase, leading to digestive problems such as diarrhoea, gas, and bloating when they consume dairy.
Is Buttermilk Safe for Lactose-Tolerant Dogs?
Yes, buttermilk can be safe for lactose-tolerant dogs in moderation.
Benefits of Buttermilk for Dogs for Lactose-Tolerant Dogs
If your dog is genuinely lactose-tolerant, buttermilk can provide some nutritional benefits when given in small amounts:
Strong Bones & Teeth
Buttermilk contains calcium, which is essential for bone health and helps prevent conditions like osteoporosis in ageing dogs. It also supports strong teeth.
Muscle Health
Protein is crucial for maintaining muscle mass, repairing tissues, and supporting a dog’s overall health. Buttermilk contains moderate amounts of protein, which can be beneficial, especially for active dogs.
Vitamins (B Vitamins & Others)
Buttermilk is a natural source of B vitamins, including riboflavin (B2) and vitamin B12, which help with:
- Energy metabolism
- Nerve function
- Red blood cell production
Additionally, it contains small amounts of vitamin A for vision health and vitamin D for calcium absorption.
Gut Health
Cultured buttermilk contains live probiotic bacteria, which may promote better digestion and gut health. These probiotics can help maintain a healthy balance of gut bacteria, reducing issues like diarrhoea and bloating.
Risks of Buttermilk for Lactose-Tolerant Dogs
Even if your dog tolerates dairy, buttermilk still carries some risks, especially if given in large amounts.
Digestive Upset from Overconsumption
Even lactose-tolerant dogs can develop mild stomach issues if they consume too much buttermilk. Common symptoms include:
- Loose stools or diarrhoea
- Gas and bloating
- Stomach discomfort or gurgling sounds
Always introduce buttermilk gradually and watch for any signs of discomfort, such as bloating, gas, or diarrhoea. If your dog shows any negative symptoms, stop immediately.
High-Fat Content Can Lead to Pancreatitis
Full-fat buttermilk contains a high amount of fat, which can be problematic, especially for dogs prone to:
- Pancreatitis (an inflammatory condition of the pancreas)
- Obesity (excess fat intake contributes to weight gain)
- Dogs with sensitive stomachs
Added Sugars & Flavorings in Commercial Buttermilk
Many store-bought buttermilk products contain added sugars, artificial flavourings, and preservatives, which can be harmful to dogs. Some may even contain xylitol, an artificial sweetener that is highly toxic to dogs and can cause
- Severe hypoglycemia (low blood sugar),
- Seizures
- Liver failure
👉 Always check the ingredients label and choose plain, unsweetened buttermilk with no additives.
How Much Buttermilk is Safe for Lactose-Tolerant Dogs?
If your dog can digest dairy without issues, buttermilk can be offered as an occasional treat, 1–2 times per week, to prevent digestive upset. Offer
✔ Small Dogs: 1–2 teaspoons per serving
✔ Medium Dogs: 1 tablespoon per serving
✔ Large Dogs: 2 tablespoons per serving
Remember, buttermilk should never replace water or a balanced diet designed for your dog’s nutritional needs.
Although buttermilk is safe in small amounts for lactose-tolerant dogs, prioritizing your dog’s digestive health is essential. When necessary, consider healthier alternatives that offer similar benefits without the risk of digestive upset. Options like plain yoghurt, kefir, or dog-safe probiotics provide gut-friendly bacteria while being gentler on your dog’s stomach.
Is Buttermilk Safe for Lactose-Intolerant Dogs?
No, buttermilk is not safe for lactose-intolerant dogs. Dogs that lack the enzyme lactase cannot properly digest it. This can lead to digestive discomfort, including:
❌ Diarrhea
❌ Bloating & Gas
❌ Stomach Pain & Cramping
Even a small amount may trigger these symptoms, so it’s best to avoid buttermilk entirely if your dog is lactose intolerant. Instead, consider lactose-free alternatives or dog-safe. Always consult your veterinarian before introducing new foods to ensure your dog’s health and comfort.
Conclusion: Can Dogs Drink Buttermilk?
Buttermilk can be safe in moderation for lactose-tolerant dogs, but it should be avoided for those who are lactose-intolerant. Even tolerant dogs should only have small amounts occasionally, as too much dairy can cause digestive issues.
Before adding buttermilk—or any new food—to your dog’s diet, always consult your veterinarian to ensure it’s safe for their individual needs. And remember to monitor your pup for any signs of discomfort after trying something new.

Let’s discuss some questions that might arise in your mind after reading “can dogs drink buttermilk?”
Cultured buttermilk contains lactic acid bacteria (LAB), which help with digestion and gut health. Some of the common probiotic strains found in it include:
- Lactococcus lactis – Aids in lactose digestion and supports immune health.
- Lactobacillus acidophilus – Helps with gut balance and digestion.
- Leuconostoc species – Contributes to fermentation and gut-friendly bacteria.
Streptococcus thermophilus – Assists in breaking down lactose.
- Regular Buttermilk: The liquid left over after churning butter from cream. It’s naturally low in fat and was commonly used in the past.
- Cultured Buttermilk: Made by fermenting milk with probiotic bacteria. It’s tangy, thicker, and contains live active cultures, similar to yogurt.
Yes, in small amounts! Cultured buttermilk contains less lactose than regular milk, making it easier to digest. If your puppy handles dairy well, a small amount (a few teaspoons to a tablespoon) can be safe. However:
- Avoid flavored or sweetened buttermilk (it may contain sugar or xylitol).
- Start with a tiny portion and watch for signs of stomach upset.
If your lactose-intolerant dog drinks buttermilk, symptoms like diarrhea, gas, bloating, or vomiting may appear within 1–12 hours.
- Mild cases: Symptoms usually pass in 12–24 hours.
- Severe cases: May last up to 48 hours but should improve with hydration and a bland diet.
If symptoms persist beyond 48 hours or worsen (bloody diarrhea, lethargy, dehydration), consult your vet! 🩺🐶
