Potatoes contain a great number of vitamins and minerals that can prove beneficial for your dog. These include:

  • Vitamin A, B6, and C
  • Magnesium
  • Iron
  • Potassium
  • Fiber


Just like us humans, dogs can consume carbohydrates with meat. However, eating too many carbohydrates can cause several problems. Mainly, your dog can get obese or get diabetic. Therefore, if you are feeding mashed potatoes to them, make sure they are in moderate size. 

Eating a high amount of carbs can also lead to pancreatitis. This disease is characterized by inflammation in the pancreas. Some common symptoms of it include the following:

  • Belly pain
  • Vomiting
  • Diarrhea
  • Loss of appetite

If you notice any of these symptoms in your dog after eating mashed potatoes, rush them to a vet. Although this condition can be treated. However, if left untreated, it can cause death in dogs. 

Important note: Make sure that you are not feeding raw potatoes to your dog. Raw potatoes contain solanine as a component that can be super toxic for a dog. It can lead to food poisoning in your dog. The symptoms of food poisoning in dogs may include any of the following:

  • Upset digestive system
  • Heart problems
  • Heavy or difficult breathing


If ingested in small amounts, it can be accepted by the digestive system of a dog. However, the amount of salt per day should, at no cost, exceed 100 mg for a dog that is average in size. People who often ad a lot of salt to the gravy, besides adding them directly to the potatoes, should be aware. As the high consumption of salt can lead to severe thirst in your dog. As a consequence, the dog must immediately be given a lot of water to drink. 

It does not stop there, too much water consumption leads to frequent urination. This can strain a dog’s kidneys, leaving him dehydrated. Some other diseases that are linked to salt consumption include:

  • Diarrhea
  • Vomiting
  • Nausea
  • Sodium-ion poisoning
  • Seizures

Dairy ingredients

Commonly, dairy ingredients include milk, cream, cheese, and butter. Like us, dogs can also be lactose intolerant. Therefore, if you already know your dog, you must avoid adding any of these to your mashed potatoes at all. 

Small pups usually have enough enzyme lactase so that they can digest their mother’s milk. However, when they grow up as dogs, lactase production reduces to very low. So, eating food with lactose can cause the following in them:

  • Bloating
  • Gas
  • Gastrointestinal disturbance
  • Diarrhea

Black Pepper

For the people who add black pepper to their mashed potatoes, a small amount of it is safe for your dog. However, if your food contains too much of it, keep your dog away. 


Because black pepper has capsaicin. Capsaicin is equally bad for dogs and humans. It can cause the following in your dog:

  • Diarrhea
  • Vomiting
  • Stomach disturbance
  • Irritation to eyes and nose (or mucus membrane)


Some people quite like adding garlic to the mashed potatoes, which is justified as it adds a lot to the flavor. However, it can prove toxic for some dogs. I repeat, to some. Others can eat garlic. Even some of the owners intentionally feed garlic to their dogs to get rid of fleas. Whichever is the case, it should not be fed in a large quantity. 

Dogs who are intolerant to garlic can change the shape of their red blood cells, causing them to rupture. Here are some of the signs of garlic poisoning to keep an eye on:

  • Poor health
  • Drooling
  • Weakness
  • Shortness of breath
  • Distress in gastrointestinal

Talking about the secondary ingredients, such as parsley, it is not bad for dogs. In fact, it has some anti-inflammatory and antibacterial properties.

Dill, as well, can be used to relieve diarrhea and help the digestion in dogs. Therefore, it is safe.


To conclude, in answer to the question: can dogs eat mashed potatoes, we have given the possible situations. Shortly, yes, it is safe to feed mashed potatoes to your dog if they do not contain any extra seasoning. Potatoes are nutritional for the dogs until fed in a large amount. Moreover, the cooking process eliminates all the health hazards related to raw potatoes. Avoid using too much salt, and pepper. Whereas avoid using garlic and dairy ingredients at all.
