It could be a bite, when it happened with mine the bite did just look like a line but if it's got more sore it could look like that.i just used Luke warm salt water and if they'res not much hair on it abit of savlon cream isn't gonna hurt. Mine healed lovely, but he had to be paired with another piggy as he was getting bullied.Hi, my new piggy developed a weird hair loss on her bottom, it looks like blood was drawn as well. Any suggestions? Thank you
