I believe that it is best to use an official coin wallet, it is the most reliable and secure way. If it is possible to buy a hardware wallet, it will significantly increase the security of your coins. The distribution of the wallet on GitHub is an additional guarantee of safety.
Official as always but there are good wallets such as hardware wallets that we can use for those who can afford.
Anyway, this thread has been around 1 year and I think this already gave enough information for OP and to those that are looking for the best wallet to keep their Dogecoins.
