Can Dogs Drink Milk?

Are dogs lactose intolerant?

Many are, at least to some degree. Like many mammals, dogs produce less lactase (the enzyme that breaks down lactose) as they mature past puppyhood. Puppies produce plenty of lactase because they need it to digest their mother's milk, but production decreases as they're weaned onto solid food. The degree of lactose intolerance varies from dog to dog; some handle dairy just fine, while others get gas, bloating, or diarrhea from even a small amount. You won't know where your dog falls until they try it.

What about goat milk or lactose-free milk?

Goat milk contains slightly less lactose than cow's milk and some dog owners report better tolerance. Lactose-free cow's milk is also an option since the lactose has been pre-broken down. Neither is necessary for your dog's nutrition, but if you want to offer milk as an occasional treat, these alternatives may be easier on sensitive stomachs. Avoid flavored milks, chocolate milk (toxic), and any milk with added sweeteners, especially xylitol.

Is there any benefit to giving dogs milk?

Not really. Dogs get all the calcium, protein, and nutrients they need from a balanced dog food. Milk is essentially an unnecessary extra that some dogs enjoy as a treat. If your dog tolerates it well, a small splash occasionally is harmless. But it shouldn't replace water, it shouldn't be a regular part of their diet, and if it causes any digestive upset, just skip it.
