Why is your dog so interested in your guinea pig?

Guinea pig bites are very rare.

If your guinea pig bites you, it may be because you are holding him/her in a uncomfortable position.

If you are holding hin comfortably, check over his body and make sure he hasn 't got any bites/scratches that may be irritating him.

A guinea pig may also bite/nibble if it is hungry and you have a food scent on your hands.
