Eating behavior
My dog refuses food and is vomiting, what should I do
Last updated 23 September 2026 · How we write and check this
Short answer
This combination warrants contacting a vet rather than waiting it out at home, particularly if vomiting happens more than once, continues beyond a few hours, or is paired with lethargy, since these together can point to a range of causes that need proper assessment rather than home management.
Why this combination is taken more seriously than either sign alone
Occasional vomiting in an otherwise well, eating dog can sometimes be minor and self limiting, but vomiting combined with a complete refusal to eat suggests the digestive system is genuinely upset in a way that is affecting the dog more broadly, which is a stronger signal to seek guidance.
Information worth having ready
Noting how many times vomiting has happened, what the vomit looked like, whether anything unusual was eaten recently, and how long the food refusal has lasted all help a vet triage the situation quickly, whether by phone or in person.
What not to do while waiting for guidance
Avoid offering large amounts of food or water at once, since this can trigger further vomiting, and avoid any home remedies or medications not specifically directed by a vet, since these can complicate rather than help the underlying issue.
Key takeaways
- Vomiting combined with food refusal is a stronger signal than either symptom alone and warrants contacting a vet.
- Noting the frequency, appearance of vomit, and timeline helps a vet assess the situation quickly.
- Avoid offering large amounts of food or water, or giving any home remedies, without veterinary guidance.
