Guinea Pig: Quick, Essential Care Guide
Step 1 — Quick assessment: Is this an emergency?
Is it just picky behavior or a red-flag emergency? Spot the clues fast.Check how long your guinea pig has been off food and look for red flags right away. Start by asking: has it been eating within the last 12–24 hours?
Feel the belly gently with your fingertips for bloating — press lightly, don’t prod. Lift the scruff briefly to check hydration; a slow return of skin means dehydration. Watch and note behavior.
Look for these urgent signs:
If you see any of the severe signs above, or it hasn’t eaten for more than 12–24 hours, prepare to act fast and contact an emergency vet. Record behaviors and take a short video (quiet, close-up) to show the vet — it helps them diagnose quickly.
Step 2 — Entice with safe, high-value foods
Try irresistible treats — sometimes the right snack wakes them up.Offer small amounts of high-value, safe foods that guinea pigs usually love. Put fresh Timothy hay where they can reach it at all times. Give a few plain timothy pellets and vitamin C–rich veggies like bell pepper or parsley.
Provide tempting options:
Avoid sugary fruit treats as first-line. Warm a little water and soak pellets or soft greens to make a fragrant, mash-like texture. Present food very close to the nose, on your hand, or in a shallow dish so it’s easy to sniff and nibble. Offer multiple tiny offerings throughout the day instead of one big pile. Try a gentle coaxing example—wave a warm pepper slice near the face; many pigs will investigate the smell. If they nibble, reward and keep offering frequent small portions to rebuild appetite.
Step 3 — Hand-feeding and syringe feeding basics
When hands-on is needed: feed safely without causing stress or aspiration.Make a soft mash: soak high-quality timothy pellets or alfalfa pellets (young pigs only) in warm water until mushy, or use a commercial critical care formula for herbivores (best). Warm the mash to body temperature and strain any large lumps.
Use a syringe (no needle): hold the pig upright with the head slightly elevated. Gently place the syringe tip at the side of the mouth and squirt tiny amounts so the guinea pig can swallow between drops. Stop if you see coughing, choking, or panic.
Follow these safety points:
Practice patience: offer 1–5 ml per shot for small pigs, letting them swallow each time. Seek immediate vet help if breathing changes, prolonged struggling, or inability to swallow.
Step 4 — Treat dehydration and stabilize at home
Dehydration sneaks up — here's quick first aid that helps until the vet.Treat dehydration quickly. Offer fluids via syringe slowly: give small sips of plain water or a lightly diluted unflavored electrolyte (e.g., Pedialyte 50:50 with water). Aim for tiny, calm doses so the pig can swallow between drops.
Check hydration and comfort regularly:
If dehydration looks moderate to severe, the pig won’t take fluids, or you’re unsure, go to the vet for IV/subcutaneous fluids and stabilization.
Step 5 — When to see the vet and what they'll do
Don’t wait — these signs mean a pro should take over now.See a veterinarian experienced with exotics if appetite isn’t back within 12–24 hours, or if you notice dehydration, severe lethargy, rapid weight loss, blocked gut (no droppings), obvious dental overgrowth, or breathing problems.
Expect a focused physical exam and a close dental check. Ask for radiographs (X-rays) if a gut blockage or retained food is suspected.
Expect fluids (subcutaneous or IV) to correct dehydration, plus pain relief and antibiotics if infection is likely. Expect vitamin C injections and the start of force‑feeding with a specialized critical‑care diet (for example, Oxbow Critical Care) if your guinea pig won’t eat on its own. Expect dental trims or extractions if overgrown teeth are the cause.

Early vet treatment greatly increases the chance of recovery.
Act quickly — your care makes the difference
Prompt, calm assessment and immediate supportive feeding or fluids can save your guinea pig; follow the steps above, watch for red flags, and seek veterinary care without delay if there’s no quick improvement. Try these actions, then share your results.
Short and sweet: this was exactly the step-by-step I needed. Easy to follow, calm tone, practical. Thanks for writing it!
Solid guide. Not gonna lie, I laughed a bit at myself trying to coax a 2 kg rodent with a cucumber slice like it’s a bribe. Worked, though. Syringe feeding looked scarier than it actually was. No vet yet, fingers crossed.
