Oh Mary you must be terribly worried. What a traumatic couple of weeks for you
We had a similar issues with little Chausette, she was the runt and never expected to live very long, but she went on for a year after her stroke, albeit she was deaf on one side and walked in circles some of the time.
I'm not trying to make light of the situation, and certainly know what Bonnie means to you, to all of us for that matter, but its worth staying hopeful until the investigations are complete. Every finger and paw crossed for her lovliness here.
