I have a really wonderful dog I can't keep (Seattle)

She is one quarter Great Dane, one quarter German Shepherd, one quarter Doberman, and one quarter Rottweiler.
She is a total sweetheart and love.
She has been WELL socialized and has had her puppy shots.
She is 8 months old.
She loves kids and she gets along with all other animals including livestock.
She is stunningly gorgeous with even markings that are super cute.
She is cute.
Her facial expressions are something else.
She will let you know when she needs to go out.
She is smart, too smart.
She's the best dog there is.
I want to keep her, and can't.
She is not yet spayed .
.
her litters would be out of this world with the right dad, but please don't keep her for breeding she deserves the most wonderful loving pet home ever.
I paid for this dog expecting to be able to have her for life, and am asking for half back as a fee .
.
not free as it isn't fair to me at all.
This dog is exceptional.
I will be choosy who I hand her off to.
She does need a new home as soon as possible, though .
.
we are homeless living together in a truck.
I have somewhere to go once I am dog less, assuming I have fuel enough to get that far after I manage to get back into my new storage unit so I can take my most essential stuff to start over with.
Thank you for considering her, and I.
I love this dog .
.
she is not a throw away.
