Guinea pig health: daily checks and warning signs
Guinea pigs need a daily dietary source of vitamin C, constant hay, and company. They hide illness like rabbits do, and respiratory disease can progress quickly, so breathing and appetite are the two things to watch hardest.
Quick reference
- Commonly cited lifespan
- 5 - 7 years
- Vitamin C
- Required daily from diet
- Diet by volume
- Mostly grass hay, all day
- Social needs

Commonly cited general figures for context. Requirements vary by species, breed and individual - confirm the right numbers for your pet with a veterinarian.
Check every day
- Weigh weekly on a kitchen scale and record it - steady loss is the earliest warning.
- Listen for clicking, wheezing or laboured breathing when the room is quiet.
- Check eyes and nose for discharge and crusting.
- Look at droppings and the rear end for soiling.
- Check feet for redness or swelling on the pads.
Track over time
- Weekly weight trend rather than a single reading.
- Coat quality, bald patches, and scratching.
- Overgrown nails and sore hocks from hard flooring.
- Reduced interest in vegetables or hay.

Call a veterinarian now
Any of these means guinea pigs need professional care without waiting. Do not use an app to decide whether to go.
- Laboured breathing, wheezing, or breathing with the mouth open.
- Not eating for 12 hours or more, or dropping food repeatedly.
- Sudden weakness, dragging the hind limbs, or collapse.
- Bleeding, a large swelling, or a wound.
- Straining or crying when urinating.
If your pet is in distress - collapse, laboured breathing, seizures, uncontrolled bleeding, suspected poisoning, bloat, or trauma - stop and contact an emergency veterinarian or a poison control line immediately. Do not wait for a scan result.
Common questions
- Why do guinea pigs need vitamin C?
- Guinea pigs cannot make their own vitamin C, so it has to come from their diet every day through fresh food and a suitable fortified pellet. Ask your veterinarian how much is appropriate for your guinea pig.
- Is clicking or wheezing in a guinea pig serious?
- Treat it as urgent. Respiratory disease in guinea pigs can worsen quickly, so contact a veterinarian promptly rather than waiting to see whether it settles.
- How often should I weigh my guinea pig?
- Weekly, on the same scale, and write it down. A downward trend often appears before any visible sign of illness.
