Hey so I have a long haired guniea pig and I was brushing his fur and I felt like sticky stuff on the top of his bottom ( grease gland I think ?) and it wasn’t white it was kinda dry and brown so I’m not sure if it has been their for a while and I now just noticed it ? I’m just wondering if that is Boar glue and how can I remove it properly I tried removing it with my fingers but there’s a tiny bald patch there from me doing that
