Dog Vomiting: Why It Happens & When It's an Emergency
A dog that vomits once and then acts normal is usually fine. Repeated vomiting, vomiting with other symptoms, or dry heaving without bringing anything up needs a vet.
Common causes
- Eating too fast, grass, or spoiled food
- Sudden diet change
- Swallowed objects (socks, toys, bones)
- Toxins such as grapes, xylitol or medications
- Pancreatitis, kidney or liver disease
- Infections and parasites
What the vomit can tell you
- Yellow foam — bile, often from an empty stomach
- White foam — stomach irritation or acid
- Undigested food soon after eating — regurgitation or eating too fast
- Red streaks or coffee-ground material — bleeding; see a vet
Emergency signs
- Retching with nothing coming up and a swollen belly (possible bloat — go now)
- Vomiting more than 2–3 times in a day
- Blood in the vomit
- Lethargy, weakness or pale gums
- Possible toxin or object swallowed
- Puppy or senior dog
Home care after a single episode
- Hold food for a few hours while offering small sips of water
- Then offer a small bland meal
- If vomiting returns, call your vet
