Many dog owners wonder if they can share a bowl of milk with their Shih Tzu. Since milk is a common part of the human diet, it’s natural to assume that it might be safe for dogs as well. However, while some Shih Tzus can tolerate milk in small amounts, others may experience digestive issues, allergies, or long-term health risks.
Before offering milk to your furry companion, it’s essential to understand whether milk is beneficial or harmful, how it affects their digestion, and what safe alternatives exist. In this guide, we’ll explore the pros and cons of milk for Shih Tzus, signs of lactose intolerance, and the best dairy-free options.
Can Shih Tzus Drink Milk?
The short answer is: it depends on the dog. While milk is not toxic to Shih Tzus, it can cause digestive discomfort in dogs that are lactose intolerant. Puppies have the enzyme lactase, which helps them digest their mother’s milk, but as they grow older, many dogs lose the ability to break down lactose properly.
Some adult Shih Tzus can tolerate small amounts of milk, while others may develop gas, diarrhea, or an upset stomach. Because of this, milk should be given only in moderation and with caution.
Is Milk Good for Shih Tzus? Potential Benefits
Milk does contain some nutrients that can benefit dogs in small amounts, including:
- Calcium – Supports bone and teeth health.
- Protein – Helps with muscle maintenance.
- Vitamins (D, B12, and A) – Support immune function and skin health.
- Healthy Fats – Provide energy.
However, these nutrients are already present in a well-balanced dog diet, so milk is not a necessary addition. If your Shih Tzu tolerates milk well, a small amount as an occasional treat may not cause harm.
Why Milk Can Be Bad for Shih Tzus
1. Lactose Intolerance
Lactose is a sugar found in milk that requires the enzyme lactase for proper digestion. Many adult dogs produce less lactase, making it difficult for them to break down milk, leading to digestive issues.
2. Digestive Problems
If a Shih Tzu is lactose intolerant, even small amounts of milk can cause:
- Diarrhea or loose stools
- Gas and bloating
- Vomiting
- Stomach discomfort or cramps
3. High Fat and Sugar Content
Some types of milk contain high amounts of fat and sugar, which can contribute to:
- Weight gain and obesity in inactive dogs.
- Pancreatitis, a serious inflammatory condition linked to high-fat foods.
- Increased risk of diabetes from excess sugar consumption.
4. Risk of Dairy Allergies
Some dogs develop allergies to dairy products, which can lead to:
- Skin irritations and itching
- Ear infections
- Excessive licking or paw chewing
If your Shih Tzu shows signs of an allergic reaction after consuming milk, it’s best to eliminate dairy from their diet.
How to Tell If Your Shih Tzu Is Lactose Intolerant
Not all dogs react the same way to milk. To check if your Shih Tzu can tolerate milk:
- Offer a very small amount (one teaspoon) and monitor for any digestive issues within 12–24 hours.
- If no symptoms appear, they may tolerate milk in small quantities.
- If they show diarrhea, gas, or vomiting, avoid milk completely.
Types of Milk: Which Ones Are Safe for Shih Tzus?
If you want to give your Shih Tzu milk, some options are safer than others.
1. Cow’s Milk – Not Recommended
Regular cow’s milk contains high levels of lactose, which can cause digestive problems. It is also higher in fat, making it a poor choice for dogs prone to obesity or pancreatitis.
2. Goat’s Milk – Better Than Cow’s Milk
Goat’s milk contains less lactose than cow’s milk and is often easier for dogs to digest. However, it should still be given in moderation.
3. Lactose-Free Milk – A Safer Alternative
Lactose-free milk removes the lactose, making it easier on a dog’s stomach. If you want to give your Shih Tzu milk, this is a safer choice.
4. Plant-Based Milk (Almond, Soy, Coconut, Oat) – Proceed with Caution
Plant-based milks are lactose-free, but not all are safe:
- Almond milk – Can be safe if unsweetened, but avoid if it contains xylitol, an artificial sweetener that is toxic to dogs.
- Soy milk – Some dogs tolerate it, but soy is a common allergen for dogs.
- Coconut milk – Contains healthy fats, but should be given in very small amounts to prevent stomach upset.
- Oat milk – Generally safe if unsweetened, but not necessary in a dog’s diet.
5. Puppy Formula – Only for Puppies in Need
Puppies who need milk replacement should never be given cow’s milk. Instead, use a vet-approved puppy formula specifically designed for their nutritional needs.
How Much Milk Can a Shih Tzu Drink?
If your Shih Tzu tolerates milk well, they should still only have it in small amounts and occasionally.
Recommended serving:
- Small dogs like Shih Tzus should have no more than 1–2 tablespoons of milk at a time.
- Avoid giving milk daily, as it is not necessary in their diet.
Dairy Alternatives for Shih Tzus
If your dog enjoys creamy treats but cannot tolerate milk, there are other safer alternatives:
✅ Plain Greek Yogurt – Lower in lactose and contains probiotics that help digestion.
✅ Cottage Cheese – Easier to digest in small amounts and rich in protein.
✅ Dog-Specific Milk (like goat’s milk for pets) – Formulated for dog digestion.
Common Questions About Shih Tzus and Milk
1. Can Shih Tzus Drink Milk Every Day?
No. Even if they tolerate it, milk is not necessary for a dog’s diet and should be given only occasionally.
2. Can Puppies Drink Regular Milk?
No. Puppies should only drink their mother’s milk or a vet-approved puppy milk formula. Cow’s milk can cause diarrhea and malnutrition in young puppies.
3. What Happens If My Shih Tzu Accidentally Drinks Too Much Milk?
If your dog consumes too much milk, monitor for diarrhea, vomiting, or bloating. Provide fresh water and avoid giving them more dairy until symptoms pass. If severe symptoms occur, contact a vet.
Final Thoughts
While some Shih Tzus can tolerate small amounts of milk, many experience digestive issues due to lactose intolerance. Milk is not toxic but should be given cautiously and in moderation. The safest options are lactose-free milk, goat’s milk, or dog-friendly dairy alternatives like plain yogurt.
If your Shih Tzu enjoys milk, always start with a tiny amount, watch for reactions, and choose healthier alternatives when possible. Their main source of hydration should always be fresh water, not milk.
