Can dogs have milk, or are dogs lactose-intolerant?
Can Dogs Drink Milk? Can Dogs have Milk? Most dogs can safely eat a little milk, but others are lactose-intolerant, which means that their digenstive system doesn’t have high enough levels of an enzyme called lactase that’s responsible for breaking down the milk sugar, or lactose.
Dairy foods are the biggest source of dogs’ adverse food reactions, say VCA Animal Hospitals. The intensity of each reaction varies with the ability of the dog’s digestive system to metabolize lactose and how much sugar there is in the particular food or drink, since amounts vary according to how the dairy item is processed. Certain dogs are unable to consume milk as the sugar levels are extremely high, although they will digest other forms of dairy (like cottage cheese) just fine because of the comparatively much lower amount of lactose.

Why do dogs become lactose intolerant?
Lactose intolerance is a result of undigested sugar molecules passing through the GI tract since they are unable to produce sufficient enzymes to digest the nutrients for absorption into the bloodstream. When it reaches the colon, water is then attracted to the undigested sugar molecule, causing water retention loss in the tissue walls, inflammation of the large intestine, and diarrhea in the form of loose, watery stool – a condition otherwise referred to as colitis in dogs.
Is Milk Bad for Dogs? 3 Health Risks of Milk for Dogs
Don’t feed your dog cow’s milk as it can lead to the following health problems:
- Digestive issues: Your dog’s stomach cannot process high quantities of fat, so whole milk and foods rich in saturated fats and natural sugars can cause side effects such as gastrointestinal distress, bloat, and other issues. Overeating high-fat food long-term may result in increased risk for heart disease and pancreatitis or inflammation of the pancreas.
- Lactose intolerance: Similar to humans, most dogs may not have the digestive enzyme lactase and thus may not be able to digest milk products (such as cow’s milk, cheddar cheese, and ice cream). Milk product intolerance is one of the most prevalent dog food allergies. Symptoms of dog lactose intolerance are bloating, gas, upset stomach, abdominal cramps, loose stool, and diarrhea.
- Weight gain: Dogs need fewer calories daily than humans, and with calorie-rich beverages such as milk, calories are added very rapidly and can surpass your dog’s optimal daily intake. Although surplus calories won’t be the cause of issues promptly, the health consequences in the long run involve gaining weight and obesity.
Are Dogs Lactose Intolerant?
If you’re a lactose-intolerant fur parent, you know exactly how your body responds when you treat yourself to milk, cheese, or ice cream. But did you know dogs are unable to digest lactose like we do—making them all the more sensitive to milk? It’s a fact: Our furry companions can be lactose intolerant, as well!
Cow milk has more lactose and less nutrients compared to dog milk. That, combined with the fact that as dogs mature, their ability to lactase (the enzyme that ruptures lactose) diminishes, explains why dogs find it harder to digest non-canine milk.
Your dog is probably lactose intolerant if you observe any of the following signs:
- Bloating
- Diarrhea
- Gas
- Vomiting
- Loss of appetite
- Weight loss
