Guinea pigs don’t need to be bathed very often, once a month at most. Many owners bathe their guinea pigs monthly in the summer, and every two months in the winter. The obvious exceptions to this is are if your pet is in need of an anti-parasite bath, or if you’ve had instructions from your vet to bathe them more frequently. In general, though, bathing more than once a month puts your pet at risk of skin infections and getting too cold.
