Jacob, a 9 year old American Bulldog belonging to my cousin has been convulsing, throwing up, and in generally really bad shape since late today. He was alone at home with my aunt and she panicked not knowing what to do - they're off to their emergency vet and my cousin is rushing across town now. Any vibes and thoughts that can be spared would be greatly appreciated. Jacob's had issues with really sore hips, arthritis, and gimpy legs for a while - but never anything like this.... He's got everyone panicked.
