I can't believe this is happening to your little Tango. She's such a beautiful/amazing/adorable girl, you know I looove her. She will definitely be in my thoughts, I hope she fights this.
I can only imangine how your heart aches... My thoughts and prayers are with you and your family... If it means anything, my neighors Italian greyhound a few years back slipped two discs and he only slowed down a little bit... Fingers toes and paws crossed!
Any news on the myelogram? I do hope something can be done without too much difficulty. Sending my positive thoughts your way. So hard to wait for information. Tango is such a lovely dog....what a sweet couple of pictures there. Poor girl. I do hope the pain meds work in the meantime. (((hugs)))
