We have a miniature dachsund(about 8 pounds) that is about 5 years old. She was just coming through the house and suddenly seemed unable to walk especially trouble with her back legs. She started shaking all over, a lot. We held her for about 3-4 minutes and she stopped shaking and I put her down and she took off at a run. The "spell" she had was very scary. Any ideas? No history of anything like that before.
