Merrypigs Sanctuary
Adult Guinea Pig
Any ideas on what this dark ring that has appeared could be? His brother has no signs. I thought Ringworm and so have been thinly applying Daktarin, but no improvement 
It isn't red, dry or scaly, his penis shaft feels fine underneath and it's not a lump, rather a bit raised?
I'm calling to book him in at the vets tomorrow anyway as he is suffering a rather stubborn impaction, just wondering if anyone has any ideas? Thanks in advance!
