Dogs can be known for eating just about anything, but we need only to give them safe food as responsible dog owners.

Let’s find out if dogs can eat mashed potatoes and what you need to beware of before serving to your dog.

Yes, dogs can eat mashed potatoes, however only in moderation. The mashed potatoes must be plain and not contain seasoning, cream or butter. This is the safest way to give your dog mashed potatoes. 

While dogs can safely eat mashed potatoes, please note that mashed potatoes aren’t very beneficial for dogs and don’t have many nutrients. That is why it’s essential not to overfeed them mash. Make sure you leave room in their bellies for more healthy food options.


A good balance is essential when feeding your dog. Dogs are omnivores, meaning they can eat both meat and plant to keep healthy. 

Overfeeding your dog mashed potatoes will only fill their bellies with mashed potatoes and not leave room for the healthiest stuff. That is why it’s essential only to provide your dog with a small portion.

How To Cook

Boil the potatoes in plain boiling water for around 20 minutes until soft, drain and mash them together, it’s that simple, and this is the safest way to serve mashed potatoes to your dog. Never add anything else such as seasoning, cream or butter.
