My guinea pig has a crusty, red, and bloody eye. Is it serious?

Poor Pip, it looks like she has developed conjunctivitis. It is inflammation of the eye tissue that can be caused by infection or trauma (like getting bedding in the eye). There is a chance there may be damage to the surface of the eye which could cause an ulcer, usually a vet will put dye in the eye to check for this. Ideally I would take her to a vet to have this checked, but it may be more difficult with the virus. I would ring your normal vet and see what they say about an appointment. You will need an eye drop to treat the eye a d your vet should be able to prescribe this to you based on the symptoms you describe, they may want to see it though. Make sure Pip is still eating well as pain can put GPs off food easily.

Thanks for reaching out about your guinea pig. Eyes infections, corneal abrasions (from hay, other trauma), dental disease and other ocular problems are common and should be assessed by a veterinarian, before they progress. The redness is a clinical sign of inflammation or bleeding. Good luck.

Thanks for reaching out about Periwinkle and including photos. Try cleaning the eye area with a soft moistened cloth. If appears white/creamy or persists, a veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Continue to monitor appetite. Good luck.

He needs to be seen as soon as possible by your local veterinarian. Unfortunately the signs you are describing are quite severe and concerning and possibly a gastrointestinal inflammation/infection is present. I would recommend an immediate check up, radiographs, antibiotics and supportive treatment (fluidtherapy) are required.

If your guinea pigs are fighting I would recommend placing them in separate cages. As for the one that was injured, I would recommend cleaning the wound and placing some antibiotic ointment on it if needed. If Brownie's eye looks inflamed or he is holding his eye closed then I would be worried about a corneal ulcer. If you notice this then I would recommend taking him in to be checked out by the vet.

Thanks for using PetCoach. There are several possibilities for Pietje's crusty eyes. The first is to make sure that he has adequate Vitamin C supplement. This needs to be in the form of fresh fruits and veggies as well as fresh food, and Vit C supplement (not in the water). A bit more on feeding https://vcahospitals.com/know-your-pet/guinea-pigs-feeding The other differentials include mites or ringworm. A vet visit can help diagnose either of these conditions. The vet may recommend a fungal culture or skin scraping to make a diagnosis. https://vcahospitals.com/know-your-pet/guinea-pigs-problems I hope this helps.

Mochi's eye does look like there is infection. Have her examined by your veterinarian for confirmation. She will likely need antibiotics if infection is diagnosed. Use a warm washcloth to gently clean the eye, change bedding frequently to minimize irritating dust. If you are using pine or cedar shavings, immediately clean the cage and use aspen shavings or recycled paper bedding. The cedar can be irritating and may cause liver disease.
