Full blooded Doberman puppy

He's a full blooded Doberman puppy. He's 5 months old. He is probably the best puppies I've had the pleasure of raising. However must rehome him because stuff has changed in my life that have prevented me from giving him the complete attention he needs. He is house broken. He has learned some commands. He is a fast runner, he jumps quite high, he loves children anf the husband learns extremely quick. I really do have AKC papers on him if you would like them. I paid big money for him and another $600 for professional ear cropping however will rehome him for just $400. He has only eaten grain free foods that you could take with him. Please get in touch if you are looking at him. Thanks
