My mini daschund randomly starting wobbling back and forth. She really looked like a bobble head doll, but it was her whole body. I don't know what happened to her or if this could be the result of a seziure... anyone know what I should do?

Dogs do sometimes have seizures, and they are scary. They may or may not reoccur. The prudent thing to do is to take her in for a vet check.

Labman, sorry had to spread the love around.

I agree completely with Labman. Please make an appointment with your vet.
