Help Bane with sudden illness

Please help! 

Suddenly on Sunday, My sister Tessa’s  dog
Bane’s back legs started to shake. As a
large breed my sister thought he over did it
or perhaps was starting to get stiff 
joints.

Fast forward to Tuesday and it has
gotten much worse. He no longer is able to stand for long and can not walk.  An
expensive vet bill from Tuesday evening
showed normal X-rays and blood work.
This is a concern as it now expected it may be neurological.  The  next step is a CT scan
which can run from $1500-2000 and that
doesn’t include the consultation along
with sedation or anesthesia needed to
perform it.

With Covid lockdowns, Christmas and a
new baby, this is definitely not what my
sister and her fiancé had expected to deal
with. They are very distraught and
worried for him. He is a very special and
loving dog 

I know this is a crazy time, but if you have any extra money to donate to help pay
for his medical bills, I know they would
be forever grateful. 

Thank you
