Like most dog owners, you probably want to ensure that your pup is getting the best possible nutrition. This means ensuring that they eat a well-balanced diet and get all the necessary nutrients.

But what if your dog isn’t eating as much as they should? Or if they have a health condition that requires them to eat a special diet?

In cases like these, many people question whether supplements like Ensure can help their dogs get the necessary nourishment.

Can Dogs Drink Ensure?

While a dog can technically drink Ensure, it’s not the best option.

Ensure is high in calories, salt, sugar, and fat which can lead to weight gain and other health problems in dogs. However, not all Ensure products are created equal. They have a variety of flavors, like dark chocolate, strawberry, and vanilla. They even have low-fat, sugar, and calorie options.

Flavors, including chocolate or any other toxic ingredients, should not be given to dogs. Dogs that consume these products may suffer from vomiting, diarrhea, and an upset stomach.

Cocoa powder is especially dangerous for dogs because it contains theobromine. This substance can cause an irregular heartbeat, seizures, and in some cases, death.

If you do decide to give your dog Ensure, make sure you get approval from your vet and make sure to select the low fat, sugar, and calorie options. In addition, you also want to make sure to only give them Ensure periodically, not as a meal replacement used daily.

5 Dangers Of Dogs Drinking Ensure

Now that we know the answer to “can dogs drink Ensure,” it’s important to understand the dangers of it.

Here are some risks you need to be aware of when giving your dog Ensure:

#1 Flavors

The flavors and sweeteners in Ensure are not good for dogs. In fact, they can be toxic.

Flavors such as Chocolate contain toxic compounds that can be harmful to dogs.

So always be sure to check the label and make sure the flavor you are giving your dog is safe.

#2 Lactose

While Ensure says their product is okay for lactose intolerant people, the same may not apply to dogs.

Dogs that Drink Ensure could experience vomiting and diarrhea due to the lactose in the product.

#3 Overeating

Another danger of Ensure is that it can lead to overeating. And as we all know, eating too much can lead to obesity and other health problems down the road.

A dog’s biggest issue with overeating is Pancreatitis and bloat, both of which are life-threatening if left untreated.

Since Ensure is high in fat and sugar, both of these conditions could become a reality if your dog has too much.

Bloat can happen when a dog eats too fast or drinks too much water after eating. As a result, the stomach expands and puts pressure on other organs. This can be life-threatening and needs to be treated immediately by a vet. 

Pancreatitis is another serious issue caused by overeating. It’s an inflammation of the pancreas and can cause vomiting, diarrhea, and abdominal pain.

#4 Sugar

Ensure contains added sugar that has harmful effects on both people and dogs. The more sugar a dog is exposed to, the greater its health risks are.

Here are a few repercussions of feeding dogs too much sugar:

  • Upset stomach
  • Vomiting
  • Diarrhea 
  • Weight gain & obesity
  • Diabetes
  • Heart disease 
  • Joint problems

Sugar can also lead to hyperglycemia, which is a medical condition characterized by too much sugar in the blood. This can be extremely dangerous and lead to serious health problems.

Dogs’ systems cannot process sugar as well as humans, so even small amounts of sugar have a greater impact on them than on us.

#5 Allergies

Ensure also contains soy, which is a common allergen in dogs. If your dog is allergic to soy, drinking Ensure could cause itching, swelling, and difficulty breathing.

What Happens If Dogs Drink Ensure?

But if they drink large amounts or have it regularly, they could start to experience serious health problems. These include:

  • Weight gain & obesity
  • Diabetes
  • Heart disease 
  • Joint problems
