It certainly does sound like there is something neurological going on with Presley. The way she acted when your company was over, the weaving, are all types of behavior that can preceed a seizure. I would call the vet up asap and discuss either seeing a specialist, or having an MRI done, etc. Are there any large veterinary hospitals near you? Maybe a teaching hospital? I think it's important to find a diagnosis and start treatment, medication quickly. Poor Presley is probably very frightened. Please let us know what your vet says. Presely is in my thoughs constantly. We saying our mightiest prayers for your baby. Love, Sandra, Star and Cody
