Mouthing, chewing and swallowing
These are different descriptions of what you may have seen. Dogs Trust discusses nibbling as possible exploration without swallowing. Do not write swallowed simply because the dog's mouth touched grass. If the event was unclear, preserve unknown. None of these labels determines severity or creates permission to repeat contact.
Sequence and cause
A sequence is the order of observed events. Cause is the explanation for why something happened. Dogs Trust notes that proof of grass directly causing vomiting is lacking. Writing grass then vomiting does not establish a diagnosis, a remedy or a harmless outcome. Ask a veterinarian about the actual concern.
Prevention and treatment
Prevention planning asks how to reduce a future risk; treatment addresses an actual health problem under professional guidance. Blue Cross discusses veterinarian-led lungworm prevention. This website does not prescribe either. A current concern should not be delayed until a routine prevention worksheet is complete.
Unknown and reference
Unknown means information is not established. A reference is a source for a general statement, not individual medical advice. These tools keep uncertainties visible and link to the source; they do not measure risk, identify a plant or certify a patch. A completed note is not a health clearance.
