Can Dogs Have Oat Milk? An Honest Guide

Every pet owner knows that a dog’s diet can significantly impact their health and vitality. A key consideration in their meal planning is the type of beverages that their pets consume.

Recently, oat milk, a popular alternative to traditional dairy products, has been making waves in the world of canine nutrition.

But, can dogs have oat milk? Is it really safe for dogs? Could it possibly offer any health benefits?

Can Dogs Have Oat Milk 

This comprehensive guide will answer these questions and more.

🐾 What Is Oat Milk?

Oat milk is a plant-based beverage derived from whole oat grains. To make it, the oats are soaked in water, blended, and then strained to produce a smooth, creamy liquid. As a non-dairy substitute, oat milk has gained significant popularity due to its rich texture and mild flavor.

Nutritionally, oat milk is high in fiber, particularly beta-glucans—a type of soluble fiber renowned for its heart-healthy benefits. It is also fortified with essential nutrients like calcium, potassium, iron, and vitamins A and D.

🐾 Can Dogs Have Oat Milk?

When it comes to dogs and oat milk, the most critical question is typically whether it’s safe for canine consumption.

The answer is yes, but with a caveat—oat milk should only be given in moderation.

While oat milk isn’t toxic to dogs, it’s not part of their natural diet. Like all mammals, dogs lose the ability to digest lactase—an enzyme needed to process lactose—effectively as they age.

Although oat milk is lactose-free, it might still be difficult for certain dogs to digest, potentially causing gastrointestinal discomfort.

🐾 Pros and Cons of Oat Milk for Dogs

Looking at the benefits, oat milk’s high dietary fiber content can contribute to better digestion, reducing the risk of heart disease.

The fortified vitamins and minerals in oat milk can supplement a dog’s diet, particularly for dogs that have specific dietary restrictions or deficiencies.

Pros and Cons of Oat Milk for Dogs

However, the flip side is that too much oat milk can lead to weight gain due to its high carbohydrate content. Additionally, it could lead to bloating, gas, or upset stomach, especially if your dog is unaccustomed to it.

🐾 Recommended Serving Sizes and Frequency

The rule of thumb with oat milk, like any other treat, is that it shouldn’t constitute more than 10% of your dog’s total daily caloric intake.

For puppies or smaller dogs, a tablespoon is enough, while larger breeds can have up to a quarter of a cup. It’s also crucial not to give oat milk to your dog every day to prevent them from developing a reliance on it.

🐾 Best Practices for Introducing Oat Milk to Your Dog

Before starting your dog on oat milk, it’s advisable to consult a vet. They can provide accurate guidance based on your pet’s unique needs.

When initially introducing oat milk, start with small amounts and observe any behavioral or physiological changes in your pet. This cautious approach allows your dog’s digestive system to gradually adjust.

A common sign of an adverse reaction could be mild to severe gastrointestinal upset characterized by symptoms like diarrhea or vomiting. If you observe any such signs, stop giving your dog oat milk and consult your vet immediately.

🐾 Alternatives to Oat Milk for Dogs

While oat milk has its benefits, it isn’t the only non-dairy alternative available for dogs. Other options include unsweetened almond milk or coconut milk.

All these alternatives come with their own set of benefits and risk factors, and similar precautions should be followed while incorporating them into your dog’s diet.

Alternatives to Oat Milk for Dogs

Homemade Oat Milk for Dogs Recipe


  • 1 cup of organic, whole oats (use gluten-free oats if your dog is sensitive to gluten)
  • 4 cups of filtered water
  • A pinch of sea salt (optional and only a very small amount, as too much salt is not healthy for dogs)


  1. Rinse the Oats: Begin by thoroughly rinsing the oats under cold water to remove any impurities and excess starch.
  2. Soaking (Optional): For a creamier texture, you can soak the oats in water for about 30 minutes. This step is optional and can be skipped if short on time.
  3. Blend Together: Combine the rinsed (and optionally soaked) oats with the filtered water in a blender. Blend on high for about 30 to 45 seconds. You don’t want to overblend as it can make the oat milk slimy.
  4. Strain the Mixture: Pour the mixture over a cheesecloth, fine mesh strainer, or a nut milk bag into a large bowl. Gently squeeze or press to extract the milk without forcing through too much of the oat pulp.
  5. (Optional) Add Salt: You may add a tiny pinch of sea salt to enhance the flavor, but this is optional and should be very minimal to ensure the oat milk is safe for your dog.
  6. Store: Transfer the oat milk to a sealed container and refrigerate. Homemade oat milk can be stored in the fridge for up to 5 days. Before using, shake well as it may separate over time.
  • Do not add sweeteners, vanilla extract, or any flavoring that could be harmful to dogs.
  • Always introduce new foods into your dog’s diet in small amounts to monitor for allergies or intolerance.
