My Dog Drank Milk: What Should I Do?

It’s happened to the best of us. You mind your own business when suddenly, you see your dog lapping milk from an unattended glass.

Or maybe you caught them raiding the fridge for a late-night snack. Either way, you’re wondering if dogs drinking milk is as bad as everyone says it is. Well, the short answer is yes.

Dogs shouldn’t drink milk because it can cause gastrointestinal upset and other problems. Dairy products are also one of the dogs’ most common food allergies, so it’s best to avoid them altogether if possible.

Why Milk Is Bad For Dogs

Many pet owners don’t know that milk is bad for dogs. Like people, dogs are lactose intolerant, and consuming milk can cause discomfort and digestive issues.

If you’ve seen your dog drink milk and then have an upset stomach, it’s likely because of the lactose.

So, why is milk bad for dogs?

As we said, dogs are lactose intolerant, which means that their bodies can’t properly digest lactose, the sugar found in milk.

When lactose is consumed, it can cause gas, bloating, diarrhea, and vomiting. In severe cases, it can even lead to dehydration.

So can dogs have milk? The answer is no, and avoiding giving your dog milk altogether is best.

However, if your dog consumes milk, keep an eye on them for any signs of discomfort. And, of course, always consult your veterinarian if you have any concerns.

The Dangers of Dairy Products for Dogs

As a pet owner, you want to ensure your furry friend gets all the nutrients they need to live a long and healthy life. However, you may not know that some common foods can be dangerous for your dog.

Dairy products are a prime example. While a little milk or cheese probably won’t hurt your dog, too much can cause digestive problems. Dogs don’t have the same enzyme in their gut that helps break down lactose, the sugar in milk.

This can lead to diarrhea, vomiting, and other uncomfortable symptoms. Just keep an eye on them and see how they react. If they start to show signs of discomfort, call your veterinarian.

How to Know If Your Dog Has Eaten Milk or Cream

It’s true!

If your dog has consumed milk or cream, watch for these symptoms:

  • Diarrhea
  • Vomiting
  • Abdominal pain or discomfort
  • Bloating
  • Gas

If your dog is experiencing any of these symptoms, call your veterinarian immediately.

What to Do If Your Dog Drinks Milk

If your dog drinks milk, there are a few things you should do. First, don’t panic.

Milk is not poisonous to dogs, and they will not necessarily get sick from drinking it. However, some dogs may be lactose intolerant and experience stomach upset, diarrhea, or vomiting if they drink too much milk.

If your dog is showing any signs of discomfort, call your veterinarian. Otherwise, offer your dog some water to drink and keep an eye on them to ensure they are not drinking too much milk.
