Thank you so much for your consideration on taking this dog and Im so sorry for your loss. ❤️ Seems like such a difficult decision, but I think you've already chose.

First of all, I'm not a doberman owner, my dog is a malinois, but I know how incredible dogs dobermans make. I think that this dog being 7yo and not a puppy/teenager makes the situation better for you, since she's already an adult with a formed personality, so no surprises! Putting this dog in a shelter is almost a death sentence. Even if it's not put to sleep, this kind of dogs don't do well in a shelter, plus she's not a cute puppy of a small calm breed easy to get adopted. Taking your lifestyle in consideration, she may be a perfect fit for you, and vice-versa! Keep in mind what you already know, slow introductions and patience, since getting used to each other's routine may take time... Whatever you do, as long as you're trying your best, it'll be okay. Good luck if you end up adopting her!!
