I'm urgently placing a dog

I urgently need to give my dog a better home, there are no photos, I’m giving it away because my mother’s severe allergies have worsened, even the doctor is already saying that I need to give the dog away
Name is Greek 3 years old
He is short and long, funny, smart, knows how to give a paw and knows the word place
He understands all your conversations, is affectionate, and protects his territory 100%
He is very powerful, his bark is louder than that of any huge dog, loud and clear, suitable for protecting a garden or home
Eats everything, is friends with cats,
A mixture with a German Shepherd and we assume with this
The dog loves himself very much
Likes to lie on pillows and look out the window watching everything that happens, I leave it in good hands with an infrequent photo report
A dog is a machine, very strong and fast (can move 3 people sitting on a bench - tested
He's not just a dog, he's a man with a smart look
Please help me get it installed
I don't want to give him to a shelter, they treat them cruelly
And I don’t want to kill either. I'll pay for the taxi myself
