Why Does My Dog Have an Upset Stomach?

Quick answer

Occasional digestive upset in dogs often follows a diet change, eating something unusual, or stress. It may settle within a day. Ongoing or repeated vomiting, diarrhea, or gas can point to parasites, food sensitivities, or other conditions. Watch energy, appetite, and stool, and contact your vet if signs persist.

Common signs and what to watch for

Vomiting or regurgitation
Soft stool or diarrhea
Gas or gurgling stomach
Eating grass or licking surfaces
Reduced appetite

Repeated vomiting or unable to keep water down
Blood in vomit or stool, or black stool
Swollen or painful belly, or retching without producing anything
Possible swallowed object or toxin
Lethargy or not eating, especially in young pets

Breed and age considerations

Large, deep-chested dogs

Breeds like Great Danes, boxers, and German shepherds are at risk of bloat — a swollen belly with retching is an emergency.

Puppy / kitten

Young pets dehydrate quickly and are more prone to parasites and infections; call your vet sooner.

Adult

Diet changes and scavenging are common triggers.

Senior

Ongoing digestive changes in older pets deserve a vet check for other conditions.
