Neurology Appointment for HEMI

This is HEMI my 4 year old blue heeler. I got HEMI on my first fathers day without my dad! This lil man came to me when I needed his love the most. He has been having a hard time recently. After weeks of test and office visits we have been referred to a Neurologist.. that his problem is in his brain! NOOO!!!! So here I am. We need $150 for visit and $2000 -3000 for the MRI (these are based off quotes from 3 closest places around me who treat theses kinds of problems) and from the sounds of it I shouldn't come without being prepared to do the MRI... They did say I have time to get $ together since he is still walking and peeing on his own.
As Most of you know I don't ask for anything I don't need, but after taking the time off for my own surgeries and these last few weeks of test n vet visits I'm running out of $.. Please DO NOT FEEL OBLIGATED to help me. If you can tho.. HEMI, Pyrate and I would be seriously grateful. These guys are my life.
I appreciate your time reading about us and thank you for all your love and support.
