Can Dogs Drink Milk?
Most adult dogs are lactose intolerant. Cow's milk can cause diarrhea and gas.
Cow's Milk
⚠️ Generally NOT recommended — due to lactose intolerance and casein allergy.
If you do: max ~1.7 fl oz (50 ml) for a medium dog, monitor for 24 hours.
Lactose-Free Milk
✅ A better choice in small amounts.
Plant-Based Milks
| Milk | Safe? | Notes |
|---|---|---|
| Almond Milk | ⚠️ | Unsweetened, small amounts |
| Oat Milk | ✅ | Unsweetened, unflavored |
| Coconut Milk | ⚠️ | High fat content |
| Soy Milk | ⚠️ | Many dogs are allergic |
| Rice Milk | ✅ | Unsweetened, gentle |
RULE: All plant-based milks must be unsweetened, unflavored, vanilla-free, and salt-free!
Cocoa, Chocolate Milk
🚨 NEVER — chocolate is toxic!
