A suggestion please contact your closest Doberman Club.
Every reputable breeder I know has a "no shelter- no rescue" clause in their sales contract.
If for ANY reason the dog doesn't work out. The breeder takes the dog back and re-homes them no questions asked. The last thing they want is their dogs in a shelter or rescue scenario.
As careful as the breeders try to screen where they place their pups there are times it just doesn't work out.
Sometimes its as simple as a doberman puppy is way more work and commitment than they anticipated.
Maja is #6 for me and I knew exactly what I was getting into.
But at age 60 there was a few months I was wondering if I made a mistake as I walked around sleep deprived and exhausted for the 1st 4 months.
Glad I got her now no way I can do it again in 10 years. LOL!
Other times its just an unplanned or unforeseen life event.
Like change in job or job loss , relocation, divorce. The dog doesn't do well with children or other pets. Health issues like someone in the home develops really bad pet allergies. Has serious health issues that prevents them from caring or exercising the dog properly.
All of these things can lead to wonderful dogs being returned to the breeder and needing a new home.
You are EXACTLY the kind of person and home they are looking for.
It's a win/win they find an excellent home for their dog.
You get an excellent dog from breeder that cares about the breed and their dogs.
These breeders often have decades of experience researching pedigrees and do extensive health testing. They are dedicated to breeding the healthiest, best temperament and the best examples of the breed standard possible. If you are patient and willing to wait there is a great doberman that needs the home you can provide.
I understand that you want to rescue a Doberman that is commendable and selfless.
But be aware there are many health issues from heart to neurological to cancer problems.
You got lucky and rescued a dog that had a long and healthy life. The last thing you want or need is your next one to have heath problems or keel over suddenly from DCM. I lost a male at age 4 to DCM and I was the breeder. It was devastating.

I am not trying to discourage or scare you in any manner.
I simply wan't to help you find & rescue a doberman that you can love for many, many years to come. And avoid the heart ache that often comes with rescuing a Doberman that was bred without any regard to the genetic health problems that are prevalent in the breed we love so much.
Best regards
