Can dogs drink plant-based milk?

We all want to spoil our pets now and then give them a little treat or two. Generally speaking, dogs should only really ever drink water. Let me explain if dogs can drink any of the plant-based milk products on the market. Let’s find out which vegan milk alternative is the safest one.

Some varieties of plant-based kinds of milk are considered safe for dogs. Some of the milk have toxic ingredients to dogs. You should avoid giving your dog soya milk, coconut milk and any brands that include stabilizers, xanthan gum or even replace sugar entirely with the human-made sweetener.

You should never substitute their daily water amount for plant-based milk. Dogs need to drink water for hydration to stay healthy.

What does plant-based milk mean?

There are many types of plant-based kinds of milk. Plant-based milk, alternative milk, nut milk, or vegan milk is an alternative to milk produced from an animal’s mammary glands. Manufactured by a water-based plant extract and does not contain any dairy. Plant-based options are commonly drunk by vegans or by someone who is lactose intolerant.

Varieties of plant-based kinds of milk

Coconut milk is a milky-white liquid and is used as an alternative to dairy milk. Coconut milk is made from mature coconut pulp, shredded and blended and mixed with hot water, then drained. Coconut Milk is different from tinned coconut juice. Coconut juice is from the middle part of the coconut.

Pea Milk has one of the most complex manufacturing processes of all the plant-based kinds of milk. It is made by harvesting yellow spilt peas and milling them into flour, and the liquid protein is then separated from the starch and pea fibre leaving creamy pea milk, and guess what, it doesn’t even taste like peas.

Make sure you read the label making sure it’s the unsweetened version. Giving your dog human-made sweeteners can cause serious health issues.

Things to check before you serve your dog plant-based milk

Check the label for the breakdown of ingredients, each company that manufactures the milk will make slight amendments, and some may have more salt and more sugar than another brand. They may add stabilizers like guar gum or gellan gum to thicken up the liquid. Or they may even replace sugar completely with human-made sweeteners, which is bad for your dog.

Always read the label.

Artificial sweetener

Never give you dog plant-based milk that replaces sugar with sweetener. The sweetener is highly toxic to dogs. They must not ever have artificial sweeteners in their diet. It can cause life-threatening illnesses such as hypoglycemia (low blood sugar), liver failure, and kidney failure.

Artificial sweetener LABEL names to check for:

  • Saccharin
  • Stevia
  • Sugar alcohols (Xylitol)
  • Aspartame
  • Acesulfame potassium
  • Sucralose (Splenda)
  • Advantame
  • Neotame (Newtame)


Stabilizers can irritate your pet’s stomach lining; these are used to thicken up the milk and give it an improved mouthfeel.

Stabilizers LABEL names to check for:

  • Carrageenan
  • Pectin
  • Gellan Gum
  • Guar Gum
  • Locust Bean Gum
  • Microcrystalline cellulose (MCC)

Seek extra medical advice

If in doubt, please call and ask your veterinary for professional personal advice for your dog. You can better understand the recommendation from your vet that knows your dog and understands if your dog has any underlying illnesses that could affect them if they drink plant-based kinds of milk. You can also get a home dog allergy test to confirm if your dog is allergic to certain ingredients. Dog allergy tests can eliminate any plant-based kinds of milk they cant have

Sorry doggies out there, sometimes you gotta be cruel to be kind. I know this too well speaking from experience – Sharing your food with a dog and the risks.
