I can't find that much information about staking of Dogecoin to a wallet which is the safest place to stake a coin that you have. But there is one video that I've got a peek and it says that you can stake it on bakeryswap. I haven't heard the platform and it just so happen that it's the one to appear in the search results. I'm not recommending or vouching for it but I just have to mention since that's the detail that I've got after trying to search and help you.
