Thank you for your reply. As an update, she had for the first time a full grand mal seizure last week. It lasted almost 10 minutes and completely unconscious. When she came too, she had all the usual post seizure symptoms, walking around, bumping in walls, not know who we were, etc. she recovered over night, and all symptoms were gone and she was back to being our normal doggy. We did start her on seizure meds and she is starting to show very minor spasms again, but nothing like before and she can go on walks again. We did see a neurologist a few days ago who was a little stumped and thought either some gene mutation or a brain tumor. They wanted 3,800 for an MRI but they couldn’t really give a good reason for the MRI since we put her on seizure meds anyhow. With her heart condition, she probably can’t undergo surgery. Thank you again.
