Strange Thing Behind The Ear

[Leo&brownie]

One of my guinea pigs, Brownie, has had for some time now a strange thing behind his ear. I've tried to push it softly, thinking it might be something stuck, but I didn't succeed and I don't want to push harder in case it's more than that...

Do you know what it might be?

When in doubt or in case of concern go to the vet.
It’s always a good idea to nip a potential issue in the bud and at best to be reassured.

Hi! I would recommend to have it checked by a vet. It is difficult to say for us what exactly it is.
