Finding a good home for my Dog?

I am still trying to find a good home for my Dog-best friend and yes I have ads with all the pet finders but it is important to me to find someone that really wants him.He is 5yrs old Male-Jack Russell with papers and bloodline.He is smart and loyal and mainly a in-house dog but need s a yard to run around in.I have lost my home and now living with my 77yr old father who is going to need my help there.I am on disability myself and can't afford to take care of my Jake so this is my plight.Thank You for any help in this matter.
