Making Dog-Friendly Mashed Potatoes
If you really want to share mashed potatoes with your dog, here’s a simple dog-friendly recipe:
- Boil plain potatoes until soft
- Mash them with a small amount of water (no milk or butter)
- Let cool completely
- Serve a small spoonful as an occasional treat
Remember, even this healthier version should only be an occasional treat, not a regular part of your dog’s diet.
Better Treats for Your Dog
Instead of instant mashed potatoes, consider these healthier options:
- Small pieces of plain cooked chicken
- Carrots
- Green beans
- Commercial dog treats formulated for canine nutrition
- Apple slices (no seeds)
The Bottom Line
While a tiny bit of plain instant mashed potatoes probably won’t harm your dog, it’s not something you should intentionally feed them regularly. The high sodium content, potential additives, and starchy nature make it a poor choice for canine nutrition.
I’ve seen many dogs in my veterinary practice with tummy troubles from human foods. It’s always better to err on the side of caution and stick to foods specifically formulated for dogs.
Remember, the best diet for your furry friend is one that meets their specific nutritional needs – and that typically doesn’t include instant mashed potatoes from your dinner plate!
Your dog’s health is worth more than the momentary pleasure they might get from sampling your human food. If you want to show love through food, choose treats that are both delicious AND healthy for your pup!
A Final Thought
We all love to make our dogs happy, and sharing food can feel like a way to show love. But the best way to care for your dog is to provide them with appropriate nutrition. Save the instant mashed potatoes for yourself, and give your pup something that’s actually good for them instead!
Remember – when in doubt about any food and your dog’s health, always consult with your veterinarian. They know your pet’s specific health needs and can provide personalized advice.

Can Dogs Eat Sweet Potatoes?
Sweet potatoes are a healthier option than regular potatoes because they contain higher levels of antioxidants, vitamins (A, C, B6), and minerals than white potatoes. However, they should be incorporated with caution in the diets of dogs that are diabetic, less active, or overweight.
When feeding your dog sweet potatoes, ensure that it is cooked and that the skin is removed. Never feed your pup raw sweet potatoes because they’re hard to chew and they could easily upset their stomach or even cause intestinal blockage.
The number of sweet potatoes given will depend on a number of factors including the dog’s activity level, size, and overall health. However, as with any food, moderation is key. Sweet potatoes contain high levels of vitamin A, so too many of them might cause muscle and bone weakness.
Talk to your veterinarian before introducing any new foods into your pup’s diet. If the vet says it’s okay, start with a small amount and see how your pet reacts.
- Potatoes contain lots of nutrients that are beneficial for your dog, but they should not become a staple in their diet.
- Raw potatoes contain solanine, a compound that can be toxic to dogs. Make sure to always serve your pooch cooked potatoes.
- Raw potatoes can cause unwanted health effects such as gastrointestinal distress, weakness, and lethargy, as well as weight gain.
- Make sure to consult your vet before introducing any new food into your dog’s diet.
- Pet insurance can cover for up to 90% of vet expenses if your pet eats something they shouldn’t (like raw potatoes).
Are Potatoes Good for Dogs?
Potatoes contain a number of nutrients including vitamins A, B6, and C, as well as minerals like magnesium, iron, calcium, and potassium. These nutrients are beneficial for both humans and dogs, which implies that feeding them to your furry friend isn’t a bad thing by itself. However, potatoes also contain high levels of carbohydrates, which can be an issue for animals that suffer from diabetes or obesity. So, pups can eat potatoes but that doesn’t mean they should become a staple food in their diet.
Another issue is the amount. As with many foods, if your pooch eats too many potatoes, there can be unwanted health effects. Dogs’ bodies are designed to get most of their nutrients from animal protein, so if you decide to feed your pet potatoes, make sure it’s done in moderation. Start with a small amount to ensure that they have no problem digesting it. In general, you can share potatoes with your four-legged friend as a treat following the 10% rule, which states treats should make up no more than 10% of your pet’s daily calories.
If your dog suffers from diabetes, avoid potatoes altogether as they could cause blood sugar spikes.
