I adopted a BLM mustang recently, from a neighbor who purchased her from an auction. She is about 4 yrs old. I have bathed twice before, first two bathes of her life.
I was bathing her today and noticed thick gunk, like a moist black/brown tar-like substance, not sure how else to explain it, between her utters. It does come off but did not want to start scrubbing and pulling it off before I asked for some advice. Is this ok to remove, is it a normal build up after 4 yrs w/o bathing?
