Here's why:
* Lactose Intolerance: Most adult dogs are lactose intolerant. This means they lack the enzyme lactase needed to digest lactose, the sugar in milk. Drinking milk can lead to digestive issues like diarrhea, gas, and bloating.
* Other Issues: Milk can also contribute to:
* Weight gain: Milk is high in calories and fat.
* Pancreatitis: Milk can trigger pancreatitis in some dogs.
* Allergies: Some dogs are allergic to milk proteins.
The best beverage for dogs is plain, fresh water.
Note: Puppy milk replacer is specifically formulated for puppies and is safe for them to drink. However, adult dogs should avoid cow's milk and other dairy products.
