Eating Changes Are Usually the First Clue
A Boer goat with a sore mouth rarely announces it dramatically. She slows down. Browse and coarse forage that she would normally tear into get picked at, softer feed is chosen first, and partly chewed wads of forage appear dropped around the feeding area or spat out as cud balls. A goat who walks to the trough with real enthusiasm and then quits early, while her herd mates keep eating, is showing you a contrast worth taking seriously.
Boers are a meat breed expected to convert forage efficiently and hold condition, so a goat eating less effectively shows it in her frame fairly quickly. Feel over her ribs and spine at handling rather than judging through coat, and compare her with a similar doe on the same ground. Condition loss alongside eating changes points the investigation at the mouth early, though only a proper examination can say what is actually wrong in there.
Look Closely at How She Chews
Watch the chewing itself. One-sided chewing, exaggerated jaw movements, head tilting to keep food on one side, and pausing mid-chew all suggest discomfort somewhere in the mouth. A wet chin, dribbling while eating, or stringy saliva hanging after a mouthful are further signs to note with the date you first saw them. Repeatedly cudding and then dropping the cud, rather than swallowing and re-chewing normally, is another early pattern keepers miss because it looks like untidiness rather than a symptom.
Smell matters too. Noticeably bad breath in a goat is never a detail to file under normal, and neither is a swelling along the jawline, a lump that was not there last month, or a goat who resents her face being handled when she previously tolerated it. Note whether the signs involve eating only, or whether she is also dull, off water, or standing apart, because that wider picture changes how urgently a vet will want to see her.
What Not to Do at Home
Do not attempt to file, pull, or probe teeth yourself, and do not soften the whole herd's ration to accommodate one goat while skipping the examination, because that hides the progression without addressing a loose, broken, infected, or unevenly worn tooth, a mouth ulcer, or something lodged between teeth. General possibilities like those are reasons for a veterinary mouth examination with proper restraint and light, not conclusions you can draw from the trough side.
Separate her for a meal if competition is pushing her off feed, offer accessible forage and water she can manage comfortably, and record what she manages, what she drops, and how her condition trends over the following days. That short written run of observations is genuinely useful to the vet deciding how thorough the examination and follow-up need to be.
When the Vet Should See Her Promptly
Book a veterinary visit promptly for facial or jaw swelling, bad breath, bleeding from the mouth, a visibly loose or broken tooth, complete refusal of forage, or condition falling week on week. Seek help the same day if she stops eating altogether, cannot swallow, drools heavily and continuously, or seems painful and withdrawn. Kids and older Boer goats deserve a lower threshold still, because both have less reserve when intake drops.
At a routine herd visit, ask for mouth checks on older does as a habit, since worn teeth in a breeding doe quietly tax every kid she raises. Catching wear early lets feeding and grouping change in time to protect her condition.
