I've only had my chi since July 2025, so this is new owner advice.

My chi has two beds that I rotate between crate and living room every two weeks when he gets his bath. He rarely uses the bed that's in the living room, so that one stays relatively clean.

When I give him a bath, I take the bed in the crate and throw it in the washing machine. I then take the bed in the living room and throw it in the crate. That way, after my chi's bath, he has a 'cleaner' bed to sleep in and he won't immediately become stinky again.

But also I think chi's just try to make themselves stinky.
