How to wash stuffed animals?

Hi everyone,

My 2.5 year old is attached to this Peppa the Pig stuffed animal. It's made by TY if that matters. How can I wash this without ruining it? He brings it everywhere so it's really dirty. Every few days I try to spot wash it but its just not doing the trick. Can I throw this in the washing machine without ruining it? Any tips or tricks would help greatly. They stopped selling them as well so I can't even buy a backup.

Thank you!
