Without warning, My Sammy developed a blockage and was unable to
urinate. This started at 9pm and by midnight I was hysterical. He was
trying so hard. He sat down on the middle of the floor, lifted his head
up, opened his mouth and shook his head.  I knew i had to get help for
him immediately.  The emergency hospital I had as reference was closed
(and the owner's later explanation on why it was closed that night was
unacceptable & ridiculous).  It took me an hour to find another
hospital. We drove their at 1:20 am.  The vet examined my boy and
started treatment right away.  2 days later, he's doing much
better...getting a sonogram tomorrow. If all goes well, he'll be back
with me Tuesday morning.  I urge everyone to have not one, but at least
2 listings for emergency hospitals.
