For the most concise and comprehensive information I recommend Embark.
I can only recommend google 'doberman rescue'. This will likely pull up many results. If you add 'near me' you will get sources closer to your location. Most of all, Do Your Research!
I recommend that you contact breeders that are members of UDC and read the Puppy Buyers Guide.
