I agree with post 2,,,,contact a German Shepherd rescue. They will know best how to place the dog in the right home.
We have rescued 2 dobermans through area rescues (IL and WI) and they are wonderful and loved just as much as the dobies we got as puppies.
A breed specific rescue knows how place their dogs. The rescues we have used keep the dogs no matter how long it takes to place them in a new home and no matter what the dog’s medical needs are.
Best of luck to you and may your doggie find it’s “forever home” as soon as possible.
I’ve contacted 2 people locally. One a professional trainer who does rescues with problem dogs, but he currently is full up. He said he’d get on the phone immediately to see what he could do with various groups. He recommended another person locally involved in rescues who asked for the email to send out to various groups/people. She said most people that do rescues have other dogs, but with my dog’s socialization issues he can’t go to a foster or permanent home with animals.
