Piggy mum
Junior Guinea Pig

Porky is currently being treated for mites and is obviously very itchy. One of my others pigs spike is quite dominant and has been throwing his weight around the last couple of days, almost bullying little porky! I'm obviously going to see how it goes as he's done this before and it settled down.
However I noticed a mark on porky's ear today and I'm not sure if it's a scratch mark from him being itchy or whether it's a bite mark from spike! Any opinions would be great!
