Can Dogs Drink Cow’s Milk? Vet Approved Facts, Risks & Safer Alternatives 2025 🥛🐶 

By Dr. Duncan Houston BVSc

🥛 Introduction: Milk Isn’t Toxic, But It Isn’t Ideal

While cow's milk isn’t toxic to most dogs, it can lead to digestive upset due to lactose intolerance. Many adult dogs lack the enzyme lactase needed to break down milk sugars, which can result in vomiting, diarrhea, or gas. As a veterinarian, I advise caution and moderation—plus smarter, dog-safe hydration options. 🐾

This guide includes:

• ✅ Whether cow’s milk is safe for dogs
• 🩺 Symptoms of dairy intolerance
• 🚀 Vet-recommended milk alternatives and tips

1. Can Dogs Drink Cow’s Milk? ⚠️

Yes, but only in small amounts and not for every dog. Cow’s milk contains lactose, which can cause:

• 🤢 Diarrhea, gas, or bloating
• 🤔 Abdominal pain or vomiting
• 🧼 Allergic skin reactions (in sensitive dogs)

Vet Tip: If your dog has never had milk, start with just a teaspoon and monitor closely.

2. Signs of Lactose Intolerance in Dogs 🏥

• 💨 Excessive flatulence or gurgling stomach sounds
• 🚗 Loose stool or diarrhea
• 😞 Lethargy or inappetence after dairy

3. Safer Alternatives to Cow’s Milk 🍽️

• 🥛 Lactose-free dog-specific milk (available at pet stores)
• 🌴 Unsweetened oat or coconut milk (small amounts only)
• 🍖 Broth or bone broth (low sodium, no onions)

5. Final Thoughts from Dr. Duncan Houston BVSc 👨⚕️

Milk may seem harmless, but many dogs struggle with digesting it. If you want to treat your pup, opt for lactose-free or pet-safe options. With help from Ask A Vet, you can support hydration and health without upset stomachs. 🥛🚀
