Today Nikki suffered a seizure. I brought her to the animal emergency center. She wouldn't come out of the seizure. She kept barking and crying. The vet determined that she was suffering neurologically, She wasn't responding to stimuli etc. She was also blind. Without doing further testing, he can only assume that the cancer may have spread to her brain, or she had some type of aneurism. Regardless, it wouldn't have been fair for her to go through any suffering. My Nikki was put down at 6:00pm. She would have been 14 next month.
