PLEASE CALL OHIO STATE! This just happened to Dylan 3 months ago. My vet administered aspirin immediately and he recovered 100%. Our vets are mistaking strokes for FCE. Dylan woke up one morning, couldn't walk, knuckling on the right side, circling to the right when he could stand. The aspirin was administered within 2 hours of the stroke and within days he was back to normal. He was dragging his right legs (front and back) for 5 days, but after that there was NO deficit. He is on 1/2 of 81mg aspirin a day and is back to his happy ol' self. If you PM me, I will call you and talk to you directly. I'm passionate about making our vets aware of strokes. They learned in vet school that dogs don't have strokes, which is completely wrong.....
