Nutritional Value Of Potatoes

You may not have been aware that potatoes are packed full of nutrients. Here is some of the nutritional value of potatoes:

Potatoes also contain vitamin B6 which is important for protein metabolism. Furthermore, vitamin B6 aids in forming neurotransmitters which are important for your dog’s nervous system.

Potatoes are a great source of vitamin A, thiamin, riboflavin, niacin, calcium pantothenate, pyridoxine hydrochloride, and folates. These vitamins are all essential for your dog’s overall health.


Potatoes are rich in minerals that can benefit your dog’s health as well.

For example, it contains Potassium, which is a mineral that helps improve muscle function and strength. It is also an important electrolyte that can help with healthy body weight.

Potatoes are also rich in iron, calcium, phosphorus, magnesium, and zinc. These minerals are important for healthy bones and teeth, nerve signaling, energy production within cells, growth of new cells (healing), blood cell formation (anemia prevention), and amino acid metabolism

All of these minerals are essential for your dog’s overall health as well as helping to maintain a shiny coat, healthy teeth, and strong nails.

In addition, potatoes also have a low glycemic index – which means it won’t cause a spike in your dog’s blood sugar levels. This is beneficial for dogs who suffer from diabetes.

Potatoes also contain dietary fiber, which your dog needs to stay healthy. Dietary fiber can improve digestive health, reduce the risk of obesity, and lower blood cholesterol levels.

Risks Of Eating Mashed Potatoes For Dogs

Like with any new food your dog may be unfamiliar with or is not used to, there are some risks you need to be aware of. These include;


Potatoes can sometimes be difficult for your dog’s stomach to break down and digest. In some cases, eating potatoes may result in vomiting.

This is especially true if you feed your dog too many carbs without giving them time to digest. If they eat a large amount of potatoes, this can result in stomach pain and lead to vomiting until the food is digested.


Eating too many mashed potatoes can be bad for your dog’s waistline. If you feed your dog too many carbs without giving them other nutrients, they will gain weight.

You may also notice that dogs who eat too many carbohydrates may start to smell like yeast or sugar. This is because their bodies are unable to break down the carbs and this results in a build-up of yeast in their bodies.

In addition to eating too many potatoes, feeding your dog foods that have a high glycemic index can have the same result. This includes foods such as white bread, pasta, and rice.

Some dogs are more prone to obesity or weight gain than others, so be sure to be aware and monitor their weight.


Some dogs may experience gas, bloating, and diarrhea after eating potatoes. This can be due to the high amount of starches it contains.

Too much starch can cause problems like; flatulence, stomach upset, and changes in your dog’s stool. Mashed potatoes contain carbohydrates that can ferment, resulting in gas and diarrhea.

It is possible to feed your dog potatoes without these issues; the key is moderation. The more you feed your dog potatoes or mashed potatoes, the higher the risk of them experiencing gas, bloating, or diarrhea.

Mashed Potatoes For Dogs – Serving Ideas

Serving potatoes to your dog is not only highly nutritious, it also has benefits for their skin and coat. However, what if they won’t eat it? Here are 3 ways to serve mashed potatoes for dogs;

#1 – As A Topping On Their Food

Serve it as a topping to their kibble or regular dry dog food. By adding it as a topping, you will be able to cover up the smell of other foods your dog may find unappealing.

That way, your dog won’t notice that their food is blended with mashed potatoes and they will also benefit from the vitamins and minerals it contains.

You can introduce it as a special treat that they can munch on once or twice a week.

Be sure not to add too much as this could change the texture of their kibble or make it soggy.

#2 – As Part Of Their Balanced Meal

Another way to serve mashed potatoes for dogs is to blend them with your dog’s regular meal. This works best if you are using commercial foods that contain vegetables and other healthy ingredients.

Dogs love the taste of meat, so adding mashed potatoes will provide variety in their diet while still giving them the nutrients they need.

By giving it as part of a balanced meal, you can also ensure that your dog gets the optimum amount of nutrients they need without overfeeding them.

#3 – Unseasoned

It is always best to give your dog mashed potatoes unseasoned.

Adding too much salt or other seasonings can upset their stomach and lead to vomiting or diarrhea as well as additional health problems like dehydration.

If your dog does not like the taste of potatoes, you may want to try adding a little butter. This will make the potatoes smell and taste more appetizing.

However, you should avoid giving them garlic or onion powder. These are known to be toxic to dogs, causing them to suffer from anemia.
