Yes. Dogs can drink small amounts of milk but many dogs have difficulty digesting lactose. While milk is not toxic it can cause stomach upset in dogs that are lactose intolerant so it should only be offered occasionally and in small portions.

The table below highlights the key nutrients found in this food and how they may impact your dog’s health. Nutritional values can help determine whether a food is beneficial, should be fed in moderation, or is best avoided.
Many dogs become lactose intolerant after puppyhood because they produce less of the enzyme needed to digest lactose. This means milk may cause digestive upset in some dogs even though it is not toxic. Owners should offer only small amounts and observe their dog for signs of diarrhea or gas. Milk should not replace fresh water or balanced dog food and should only be considered an occasional treat. Never add things like sugar or chocolate that can be harmful to dogs. If your dog tolerates dairy, Greek yoghurt can be a gentler option than milk.

Here are answers to some of common questions that dog owners ask about this food's safety and nutrition
Dogs can drink milk every day in very small amounts if they tolerate lactose well but most veterinarians recommend offering it only occasionally. Many adult dogs develop lactose intolerance which means frequent milk consumption can lead to digestive upset. Because balanced dog food already provides essential nutrients milk should be treated as an occasional treat rather than a daily part of the diet.
The amount of milk a dog can drink depends on their size and tolerance to lactose. Extra small and small dogs should only have a teaspoon or tablespoon while larger dogs may tolerate a few tablespoons or a small splash. Owners should always introduce milk slowly and monitor their dog digestion because many dogs develop intolerance to dairy products.
If your dog drinks too much milk they may experience digestive upset such as diarrhea gas or stomach discomfort. Provide fresh water and avoid giving additional dairy products. In most cases symptoms improve within a day but if vomiting severe diarrhea or ongoing discomfort occurs it is best to contact a veterinarian for advice.
Puppies are able to digest their mother milk but this ability often decreases as they grow older. Once puppies are eating solid food most do not need cow milk because commercial puppy diets provide the nutrients they require. Offering small amounts occasionally is usually safe but it should not replace water or balanced meals. Introducing dairy slowly helps owners identify whether a puppy shows signs of lactose intolerance such as diarrhea or stomach discomfort.
Small dogs may be more sensitive to lactose because even a small amount of milk represents a larger portion relative to their body size. If milk is offered it should be limited to very small servings and given only occasionally. Owners should watch for signs such as loose stools gas or stomach discomfort. Because small breeds also have lower calorie needs milk should be treated as a rare treat rather than a regular addition to the diet.
Senior dogs may be more likely to experience digestive sensitivity including lactose intolerance. As dogs age their ability to process dairy products can decrease which means milk may cause diarrhea or stomach upset. If a senior dog tolerates dairy it can occasionally be offered in small quantities but many older dogs do better avoiding milk altogether. Owners should monitor digestion closely and prioritise balanced dog food and fresh water.
For overweight dogs milk should be limited because it adds extra calories and fat without being necessary for a balanced diet. Even small servings can contribute to excess energy intake when given frequently. If an owner wants to provide occasional treats for an overweight dog low calorie options such as small pieces of dog safe vegetables are usually a better choice. Milk should only be given rarely and in very small amounts if tolerated.
