Hello.....When is the last time she had a full blood panel?? Did she have one (Or partial) before her dental?? Was it good the last time she had one????
Have you thoroughly evaluated her food and treats & ruled them out as culprits?
How about Flea/tick meds or Heartworm pills.....
In a Doxie, IVDD (Intervertabral disk disease) could be the culprit....Dachshunds are prone to it...
Please, let us know what the Vet says.....I'll be anxious to see if the bloodwork offers any clues.....Thank you
I could be wrong about the drunk walking, i could of spooked her when i saw her eathing out of another dogs dish i didnt yell or anything, but the head shaking was so out of the blue and she was sleeping on couch beside me.
Are you sure these were seizures?
Please do take her into the vet's for assessment as soon as you can. But it is possible this could be either an ear problem, or vestibular syndrome.
