Degu Not Eating: Dental Pain, Illness, or an Emergency?

A degu not eating is an urgent symptom, not a diagnosis. Dental disease is a major possibility, but breathing trouble, gastrointestinal disease, pain, urinary or reproductive problems, masses, overheating, and other illness can also suppress appetite; contact an exotic veterinarian the same day.

Is the degu truly not eating?

Watch rather than judging the food bowl alone. A degu may approach food, take it, chew slowly, drop pieces, select only soft items, or stop after a few bites. Check hay and pellets, water use, droppings, body weight, posture, breathing, and social behavior. In a group, briefly supervise individual access rather than separating a bonded degu for long periods without veterinary guidance.

Observation	What it may suggest	What to record
Dropping food, wet chin, long chewing	Dental or oral pain	Foods attempted, drool, facial symmetry
Smaller or fewer droppings	Reduced intake or impaired gut movement	Number, size, moisture, last normal output
Sneezing, nasal sound, labored breathing	Respiratory or nasal disease	Video at rest, discharge, effort
Swollen abdomen or repeated stretching	Abdominal pain or distension	Onset, stool, urine, food access
Excess thirst, urine change, weight loss	Metabolic or urinary disease	Daily weight and water trend

Dental disease is among the most common reasons chinchillas and degus present for veterinary care, and affected animals often show weight loss, reduced intake, or drooling.[1] In a rescue-center cohort of 225 degus, dental disorders were recorded in 34.7%; that is a defined population, not the prevalence for every pet degu.[2] Importantly, cheek-tooth and root disease may be missed during a quick awake look.

What can you do safely while arranging care?

Keep the enclosure quiet and within the degu's established safe temperature range. Offer the normal grass hay, usual plain pellets, and water in familiar containers. You may offer the usual safe leafy food if it is already part of the diet, but do not replace the diet with sugary fruit, honey, or treats to tempt eating. Degus have species-specific glucose-metabolism concerns, and sudden diet changes can complicate the picture.

Record weight on a gram scale if this can be done without a struggle. Photograph droppings and any facial swelling or discharge. Bring food labels, bedding information, medication or supplement packages, and a video of chewing or breathing. The degu overgrown-teeth guide explains oral warning signs, while the degu bloat guide covers painful abdominal distension.

Do not trim incisors, force the mouth open, syringe-feed a weak or breathing-compromised degu, give human pain medicine, or use leftover antibiotics. Some antibiotics can be dangerous in hindgut-fermenting small mammals, and assisted feeding can be unsafe when obstruction, severe distension, swallowing difficulty, or respiratory distress is possible.

When to See a Vet

Call your vet today if:

• Your degu skips a usual meal, eats markedly less, drops food, chews slowly, drools, or has a wet chin.
• Droppings become fewer or smaller, body weight falls, or the abdomen appears enlarged.
• Drinking or urination changes, the face becomes asymmetric, or eye or nasal discharge appears.
• Appetite improves briefly and then declines again.

Go to the ER immediately if:

• Breathing is labored or open-mouthed, the degu is blue or very pale, or cannot stay upright.
• The abdomen is rapidly enlarging or tense, there are no droppings with severe lethargy, or repeated unproductive straining occurs.
• The degu collapses, has a seizure, is unresponsive, or feels cold and weak.

What will the veterinarian investigate?

A species-aware examination includes weight, hydration, temperature, breathing, abdominal palpation, oral and facial assessment, and review of husbandry and diet. Sedated oral examination and skull imaging may be needed because endoscopy-guided inspection plus diagnostic imaging detects oral disorders that routine inspection can miss.[1] Research in degus found radiographic assessment useful for apical cheek-tooth elongation, which may precede obvious crown changes.[2]

Depending on findings, the clinician may add radiographs, blood glucose and chemistry testing, blood count, urinalysis, fecal testing, ultrasound, or sampling of a mass or discharge. Intranasal tumors are an uncommon but documented differential in degus with upper-airway signs followed by anorexia; a 20-case series used radiography and CT to characterize lesions.[3] This does not mean a degu with appetite loss has cancer—it illustrates why breathing and nasal signs change the diagnostic plan. The degu diabetes guide explains why thirst and urine observations also matter.

This guide supports triage but cannot diagnose an individual pet; an examination and testing may change the next step.

Frequently Asked Questions

How long can a degu go without eating?

Do not use a fixed hour cutoff to delay care. A clear appetite reduction warrants same-day exotic-vet triage, and weakness, breathing difficulty, severe swelling, or absent droppings increases urgency.

Can overgrown teeth make a degu stop eating?

Yes. Incisor or cheek-tooth disease can cause slow chewing, dropped food, drooling, selective eating, and weight loss, but a quick look at the front teeth cannot exclude deeper disease.[1]

Should I syringe-feed a degu that will not eat?

Only after a veterinarian assesses whether assisted feeding is appropriate and shows you how. It may be unsafe with obstruction, severe bloat, respiratory distress, or impaired swallowing.

Will a degu start eating again on its own?

A brief environmental disruption may pass, but persistent or marked appetite loss should not be watched at home. Treating the underlying pain or disease is more important than temporarily tempting food.

Is appetite loss contagious to other degus?

The symptom is not contagious, but some respiratory or enteric causes can spread. Maintain hygiene and ask before separating bonded animals, because isolation also causes stress.

Can a degu that is not eating be cured?

Many causes are treatable, but prognosis depends on the diagnosis, severity, duration, and whether normal chewing and gut function can be restored. Dental disease may require ongoing management.

How much does a degu appetite-loss workup cost?

Cost depends on exotic examination fees, sedation, dental imaging, body radiographs, laboratory tests, hospitalization, and procedures. Ask for a staged, itemized estimate based on the first examination.
