Potatoes are poisonous to dogs

Are dogs actually allowed to eat potatoes?

Many dogs are downright crazy about human food. But not everything is tolerated by the four-legged friends. In this post, we'll explain if and when potatoes are good for dogs.


Never feed potatoes uncooked

First things first: Potatoes (Solanum tuberosum) should never be fed raw, only boiled. Raw tubers contain solanine, a chemical compound that is also slightly toxic to humans and which can lead to symptoms of poisoning in dogs. As a rule, your dog will not get sick straight away from a small, uncooked potato - in this case the dose actually makes the poison. However, even slightly larger amounts inevitably lead to problems. To avoid this, pay attention to these tips when preparing the tubers:

  • do not give raw potato pieces
  • do not feed the potato peel (not even cooked!)
  • always cut out green areas (high solan content)
  • Boil the potato tubers well
  • shouldn't be raw on the inside either

Boiled potatoes are an important source of carbohydrates when barfing dogs, and the healthy tubers also provide many valuable vitamins and minerals.

Note: Which types of potatoes you offer your dog is up to you and your four-legged friend's taste. Floury varieties, however, contain more starch and can cause problems with sensitive stomachs.

Signs of solanine poisoning

If your dog has eaten raw potato pieces (for example because he stole some from you while peeling it for lunch), you should keep an eye on the animal in the following hours. Does it show one or more of these symptoms:

  • diarrhea
  • irritated mucous membrane
  • cramps
  • or paralysis

then you should visit a veterinarian or veterinary clinic immediately. However, these signs often only appear after large amounts have been eaten. How and whether the contained solanine is toxic for the dog also depends on the size of the animal and its constitution. You usually don't have to worry about a small potato or even just a piece of it.

How much to feed potatoes

Boiled potato pieces are actually healthy for the dog as part of a BARF diet or as a light food for gastrointestinal complaints. A dog weighing around ten kilograms can eat up to 80 grams of it per day, a larger animal correspondingly more. However, do not feed the nightshade plant every day, but vary the recipes - otherwise the animal may refuse the feed immediately.

Tip: Instead, you can feed your dog soft-boiled white rice. This is completely unproblematic and a good source of carbohydrates.

Be careful with potato flakes

Some dog owners swear by potato flakes, such as those contained in instant mashed potatoes, as they are guaranteed to contain no toxins. In principle, you can give these to your dog, but only in small amounts: The problem here is not the solanine, but the potassium it contains. Potato flakes contain a lot of potassium, which in high doses initially has a diuretic effect, but also slows down your dog's heartbeat. If your dog looks beaten after eating potato flakes, you should therefore take him to the vet. In the worst case, cardiac arrest could even be threatened.

frequently asked Questions

Dogs are carnivores, why should they eat potatoes?

In fact, various scientific studies have shown that over the millennia, dogs have adapted their eating habits to that of humans. Therefore, its nutritional requirements cannot be met by meat alone, which is why carbohydrates and vegetables must be part of the daily diet. The dog is just not a wolf, but is now viewed more as an omnivore.

Which vegetables are still poisonous for dogs?

Other nightshade plants such as tomatoes, peppers and eggplants are poisonous for your dog, at least when raw and should therefore only be served well cooked. Other vegetables such as onions, garlic, rhubarb and avocado are even not allowed to be fed at all. All types of cabbage and legumes such as beans, peas and lentils can, however, be cooked, but only in small quantities, as they can lead to gas.
