Bok choy and dogs: the plain vegetable is fine, the stir-fry is not
Safe with preparation
Plain, chopped bok choy served steamed or boiled is safe for dogs in small amounts, but the garlic, onion and soy sauce in a typical stir-fry are not.
Fine once the unsafe parts are removed.
Yes, with preparation. Plain bok choy, chopped small and served steamed or boiled, is safe for dogs in small amounts. The real danger is the usual restaurant preparation: garlic, onion, and soy sauce in a stir-fry are toxic or too salty, not the vegetable itself. Serve it unseasoned, and keep portions treat-sized.
- Safe form
- Both the dark green leaves and the pale crunchy stalks, served plain and chopped into small bite-sized pieces. Steamed or boiled is the best form; AKC notes cooked cabbage-family greens are less likely than raw to cause digestive upset, though raw is not toxic. Keep it to a treat-sized portion, with all treats combined staying at or under 10% of daily calories.
- Unsafe form or part
- Any cooked or restaurant preparation: bok choy is most often stir-fried with garlic, onion, scallion, soy sauce, oyster sauce, sesame oil, or butter. Garlic and onion are the genuine toxin here, soy sauce and oyster sauce carry heavy salt, and oil or butter adds pancreatitis-level fat. Also avoid whole uncut leaves and stalks (the long fibers are a choking risk), and large or daily quantities.
- Preparation
- Wash, trim the tough base, and chop both leaves and stalks into small bite-sized pieces. Steam or boil plain, with no oil, butter, salt, garlic, onion, or sauce of any kind, then cool before serving. Introduce a small amount first and watch for gas or loose stool. Keep bok choy and all other treats to no more than 10% of daily calories.

If your dog has already eaten bok choy
If the dog ate plain, unseasoned bok choy, no emergency action is needed. Watch for gas, vomiting or diarrhea over the next 24 hours, keep fresh water available, and skip further servings until stools are normal. If it ate a seasoned or stir-fried dish containing garlic, onion or scallion, or a large salty amount, note roughly how much was eaten and call your veterinarian or ASPCA Animal Poison Control at (888) 426-4435. Signs to report include vomiting, weakness, pale gums, red or brown urine, rapid heart rate or panting. If the dog gagged, retched or struggled to breathe right after swallowing a large piece, treat that as an immediate choking emergency.

Which form of bok choy the sources actually cleared
Both the leaves and stalks of bok choy clear the bar once they are cooked and served plain, chopped into small bite-sized pieces. Steamed or boiled is the preparation this record points to specifically. Raw bok choy is not described as toxic, but cooked is the form actually recommended, since raw cabbage-family vegetables are more likely to cause digestive upset than cooked ones. The stalks in particular need to be cut down from their naturally tough, stringy shape before they count as the safe form.
Preparing bok choy for a dog
Wash the bok choy, trim the base, and cut both leaves and stalks into small pieces before cooking. Steam or boil it plain, with nothing added: no oil, butter, salt, garlic, onion, or sauce. Let it cool before serving, and offer a treat-sized amount rather than a side dish. Start with a small amount and watch for gas or loose stool before offering it again.
What actually goes wrong
- Gas, bloating and stomach upset from the high fiber and water content, which is the most common complaint. Choking on the long fibrous leaves and stalks if not diced, especially in small dogs and fast gulpers. The largest real-world risk is not the vegetable but what it is cooked with: ASPCA notes allium species (onion, garlic, chives) cause gastrointestinal irritation and red blood cell damage leading to anemia, and soy or oyster sauce delivers excess salt. Cabbage-family vegetables also contain goitrogenic thiocyanate, which PetMD says can interfere with thyroid function in large amounts but is unlikely to matter unless a dog eats a lot regularly; relevant mainly for dogs with hypothyroidism or on thyroid medication. Sources do not disagree. Note on sourcing: AKC is the source that names bok choy explicitly; PetMD and ASPCA cover the cabbage family and the seasoning hazards rather than bok choy by name.
The genuine hazard with bok choy is almost never the vegetable itself; it is what it is typically cooked with. Restaurant and home stir-fries commonly include garlic, onion, and scallion, which are toxic to dogs, plus soy sauce and oyster sauce, which are heavy in sodium, and oil or butter, which adds fat that can trigger pancreatitis. Whole, uncut stalks and leaves also present a choking risk from their long fibers, separate from the seasoning question entirely. A plain cooked serving in a small amount avoids all of these.
How much counts as too much
All treats combined should generally stay within 10% of daily calories for a healthy adult dog in ideal body condition; individual needs vary.
The table below is the WSAVA reference allowance, printed as published. It is not a portion of bok choy: it is the total treat-calorie ceiling that everything given outside meals has to fit inside. Average healthy adult dog in ideal body condition. A veterinary team should set the individual dog's daily energy requirement.

What these sources do not settle
The guidance clears a small plain serving but does not give an exact portion size or say how often bok choy can be offered. Cabbage-family vegetables can affect thyroid function in large amounts, so a dog with a thyroid condition is a conversation for your veterinarian rather than something this page resolves.
