Dogs can have milk in small amounts if they are not lactose intolerant, but it should be given only occasionally and in moderation. Many dogs are lactose intolerant, meaning they have trouble digesting lactose, the sugar in milk, which can cause symptoms like diarrhea, vomiting, and gastrointestinal upset. Milk is also high in fat and sugar, so frequent or large amounts can lead to obesity and pancreatitis. Puppies can drink their mother’s milk safely, but cow’s milk and other dairy sources are not recommended for most dogs due to the risk of intolerance and digestive issues. Some dairy products like natural yogurt and kefir may be better tolerated because the fermentation process reduces lactose content. Always consult a veterinarian before giving milk to a dog as a treat. In summary:

• Small quantities of milk (a few tablespoons) occasionally may be safe for some adult dogs without lactose intolerance.
• Many dogs are lactose intolerant and can suffer digestive problems from milk.
• Milk has high fat and sugar content, posing risks like obesity and pancreatitis if given in excess.
• Puppies can digest their mother’s milk but cow’s milk is not suitable for them.
• Fermented dairy products can be easier to digest.
• Veterinary advice is recommended before introducing milk.
