The proper way to bathe a guinea pig is by using a small container or sink filled with warm water that reaches up to their belly but not their head. You can use a gentle shampoo made specifically for small animals or guinea pigs. Make sure to support your guinea pig's body during the bath and dry them thoroughly with a towel afterwards to prevent them from getting cold. It's important to only bathe a guinea pig when necessary, as they are naturally clean animals and over-bathing can cause skin issues.
