Is Milk Bad for Dogs? 3 Health Risks of Milk for Dogs
Do not give cow’s milk to your dog as it can cause the following health issues:
- Gastrointestinal problems: Your dog’s physiology cannot digest excess fat very well, so natural sugar and high-saturated-fat foods—especially whole milk—are bound to generate side effects like gastrointestinal upset, bloating, and other gastrointestinal problems. Long-term problems of overeating high-fat food include the risk of heart disease and pancreatitis, or inflammation of the pancreas.
- Lactose intolerance: Similar to humans, some dogs cannot consume the digestive enzyme lactase, which prevents them from being capable of digesting milk products (such as cow’s milk, cheddar cheese, and ice cream). Intolerance to milk products is one of the most common dietary allergies in dogs. Symptoms of lactose intolerance in dogs are bloating, gas, upset stomach, abdominal pain, loose stool, and diarrhea.
- Weight gain: Dogs require fewer calories per day than humans, and with calorie-laden drinks like milk, calories add up quickly and push your dog’s ideal daily amount beyond. While unwanted calories won’t necessarily cause problems right away, the long-term health effects that can build up are weight gain and obesity.

Milk is also rich in fat, natural sugars, and calories; it leads to obesity, pancreatitis, and other complications when fed in excess amounts. It can even lead to gastrointestinal upsets like vomiting, diarrhea, flatulence, and stomach cramps even if fed in moderate amounts. Dogs also become allergic over time to the proteins in milk.
How to Tell If Your Dog Is Lactose Intolerant
Dogs can have varying degrees of lactose intolerance; some can exhibit mild symptoms, but others are more severe. The most common symptoms include:
- Loose stools
- Gas
- Vomiting
- Abdominal pain
- Diarrhea
Their owners do not usually know their dogs are lactose intolerant until they offer them milk. It can also be hard to determine if your dog is lactose intolerant or not if your puppy consumed a lot of milk; that will also lead to vomiting and diarrhea even in non-lactose intolerant dogs. If your dog does have the symptoms after eating a small amount of milk, then you must attempt another treat. Can Dogs Have Milk? Can Dogs Drink Milk?
