I took my 5 month old boy, Atreus, to the vets this morning. He's currently one week post-op from being neutered. His incision appears to be healing well there's just a bit of swelling present, so we've been prescribed some more anti-inflamatory medication. However, the actual reason I took him to the vets is because his penis looks very swollen and just doesn't look right. The vet said it looks like it's bruised from potentially being over-groomed but she didn't seem too concerned. The vet nurse then added that they don't see many guinea pigs and she wasn't really sure if what she was looking at is okay. Please can someone advise me on what to do? Thanks x
