Guinea pigs only need to be bathed once a month in the summer, and every two months in the winter. This is unless your pet needs of an anti-parasite bath, or if you’ve been told by a vet to bathe them more frequently. In general, too much bathing puts the animals at risk of skin infections and chills.
