Can Dogs Eat Quinoa?

Yes. Most dogs can eat a small amount of plain quinoa that has been rinsed and cooked. The AKC says quinoa is generally safe for dogs and shows up in some dry dog foods, with two cautions: the natural coating on the seeds can irritate a dog's gut, and some dogs just do not digest it well.

If your dog helped themselves to a spoonful of plain cooked quinoa, carry on and watch for a soft stool. If it was a quinoa salad or bowl made with onion, garlic or a rich dressing, the next section explains what to check.

Key takeaways

Plain, rinsed, cooked quinoa is generally safe for dogs in small amounts.
Rinsing before cooking washes off some of the saponins, the bitter coating that can irritate the gut.
Some dogs react with vomiting, diarrhea or constipation, so start with a little.
Quinoa salads and bowls often contain onion, garlic and salt, which are the bigger worry.
Quinoa is an extra alongside complete dog food, never a replacement for it.

The ASPCA says any plant material can cause vomiting and stomach upset in dogs, and its advice when you think your dog may be ill is to contact your vet or its 24-hour poison line. Have ready the product name, the ingredients, how much your dog ate, your dog's weight and when it happened.

Call right away if your dog keeps vomiting, has a lot of diarrhea, a painful belly, weakness, tremors, trouble breathing, collapses or refuses food for a long stretch.

Rinsed, raw, flour and the rest: which forms are fine

Form	Okay for dogs?	Why
FormRinsed and cooked, plain	Okay for dogs?Yes, a small amount	WhyThe form the AKC recommends
FormRaw or dry seed	Okay for dogs?Not the best choice	WhyHarder to digest and may keep more saponins on the surface
FormFlour, flakes, puffs or powder	Okay for dogs?Check the label	WhyConcentrated and often mixed with other ingredients
FormQuinoa salads and bowls	Okay for dogs?No	WhyUsually seasoned, often with onion or garlic
FormQuinoa milk or drinks	Okay for dogs?No	WhyMay contain sugar, salt, oils, flavorings or sweeteners
FormDog food made with quinoa	Okay for dogs?Yes	WhyJudged by its full ingredient list, like any dog food
FormPlant, leaves, stems and husks	Okay for dogs?No	WhyThe husk is where most of the saponins sit

Saponins are natural soap-like compounds that coat quinoa seeds. A study of quinoa husks by Zhang and colleagues measured them at about 2% to 6% of the husk's weight, and found that sweet quinoa varieties can carry far less. Rinsing the seeds under the tap before cooking takes off some of what sits on the surface.

How much quinoa to give, and how to cook it

Start with a spoonful mixed into your dog's usual food, and give a small dog less than a big one. If that goes well, a little now and then is fine. The AKC's guide to homemade dog food treats quinoa as one optional ingredient in a balanced diet, so it should not take the place of complete dog food.

Rinse the dry quinoa in a fine strainer under running water.
Cook it in plain water until soft. No salt, broth, butter, oil, onion or garlic.
Let it cool.
Offer a small amount the first time, and stop if your dog gets a loose stool, vomits or strains.

If your dog has kidney or bladder stones, ask your vet first. The AKC lists quinoa among foods that contain calcium oxalate, which can matter for some of those dogs. Dogs with pancreatitis, diabetes or kidney disease should not get seasoned or oily quinoa dishes without their vet's say.

Signs to watch for, and when to call

The AKC names vomiting, diarrhea and constipation as the signs of a dog that is not handling quinoa well. A dog might also have a sore belly or skip a meal. From a small serving of plain cooked quinoa, a short bout of stomach upset is the realistic worst case, and it usually settles.

Signs that start after a seasoned dish may come from the recipe instead. Onion and garlic can be toxic to dogs, and Can dogs eat onions? explains what to watch for.

"My dog eats quinoa all the time and has never had a problem"

That is very likely true. Quinoa goes into some dog foods, and many dogs eat it with no trouble at all. What decides how a dog does is the amount, the dog's size, whether the quinoa was rinsed and cooked, which variety it was, and the dog's own stomach. The AKC notes that some dogs struggle to digest it. Your dog's easy history is real. A different dog, a bowl of dry seed from the pantry, or leftover quinoa salad full of garlic is a different situation.

Quinoa salad, flour, milk and look-alikes

Quinoa salads and grain bowls: often dressed with garlic, onion, salt, oil or cheese. Keep them for people.
Quinoa flour and flakes: a more concentrated form of the seed, and mixes and baked goods can add sugar, salt or other ingredients. Read the label.
Quinoa protein powder: check the full ingredient list for sweeteners such as xylitol, and call your vet if your dog ate a lot.
Quinoa milk: can contain sugar, salt, oils, flavorings or sweeteners. Water is the better drink.
Red, black, white and tri-color quinoa: the same plant in different colors, so the same rules apply.
Kañiwa, amaranth and wild goosefoot: related or similar seeds, but different plants. The quinoa answer does not automatically cover them.
Rice: another plain, cooked side dish many owners share. Can dogs eat rice? covers white, brown and fried rice.

Questions about dogs and quinoa

Can dogs eat cooked quinoa?

Yes. Plain cooked quinoa is generally safe in small amounts. Rinse it before cooking and leave out salt, onion, garlic, butter and oil.

Can dogs eat raw or dry quinoa?

It is not toxic, but cooked is the better choice. Dry quinoa is harder to digest and may carry more of the saponin coating. If your dog ate a lot from the bag, watch for stomach upset and call your vet if it appears.

What if my dog ate quinoa with onion or garlic?

Call your vet or a poison line. The onion or garlic is the concern, not the quinoa. Have the ingredients, the amount, your dog's weight and the time ready.
