How a 10kg dog processes a handful of greens
At this body weight, several raw mustard greens equate to a minor dietary variation rather than an overload. Their stomach acid will break down the cellulose fairly efficiently, though you might notice increased bowel movement frequency as the fiber passes through.
Chewing is the wild card here — a dog that gulped them whole may experience more noticeable gas as gut bacteria ferment the undigested plant matter. This often sounds worse than it is, manifesting as rumbling noises or passing gas without systemic illness.
The critical first six hours
Water access is your priority now, as fiber draws fluid into the digestive tract. Encourage drinking without forcing it. Temporary thirst increase is normal, but frantic lapping could indicate nausea developing.
Normal play and rest patterns are good signs. If your dog seems lethargic or keeps adopting the 'prayer position' (front down, rear up), those warrant a vet call. Likewise, any vomiting that includes bile or occurs more than twice means professional evaluation.
Why quantity changes the equation
A handful spreads across many leaves, diluting any potential irritants. Contrast this with eating the same volume of a single toxic plant — dispersion matters. The greater risk here would be intestinal blockage if your dog swallowed stems whole, extremely unlikely with mustard greens' tender structure.
Watch stool consistency rather than frequency. Slightly loose but formed movements are expected, while watery diarrhea suggests individual sensitivity needing veterinary diarrhea protocols.
When to resume normal feeding
Unless symptoms appear, continue scheduled meals to maintain digestive rhythm. Some owners withhold food after plant ingestion, but this can backfire by causing hunger-induced grass eating. A bland meal of boiled chicken and rice can soothe mild stomach upset if needed.
Prevent repeat incidents by storing greens in sealed containers — dogs often revisit 'successful' food theft locations. If your dog seems drawn to greens, introduce steamed green beans or broccoli florets as safer supervised alternatives.
