Hello I'm new to this forum, as well as a relatively new owner to my guinea pig, Charlie. I'm making this post because I need help with a terrifying discovery I found today. When I lifted him today I saw a little patch at the bottom of his stomache. Upon further investigation I found that there was this "worm like" bump on him that had a black head on it. I can give more details if you need it, I also tried taking a picture but it didn't come out clear because he doesn't like being in that position and was fidgeting around. I post this under infection because I have no clue what else it might be. Any hello would be greatly appreciated <3
