If by safe you mean usda or university extension offices or nchfp resources....
they don't have methods for wieners or hot dogs.
It might be because sometimes they are cured, cured meat is generally not canned. It might be because of additives or milk products, milk products are not safe for canning. It might be because of density issues with enough heat penetrating to the middle of the can.
They do allow sausage if loose and ground, or cut and fresh seasoned (not cured). The casing may prove to be a problem with hotdogs.
If you are looking for resources for rogue canners, survivalists, pinterest, there's lots of resources on the net for that.
Sorry I couldn't be more help.
