Any chance this puppy got into some chocolate?
My dad's dog got into some and the after effects were seizure like twitches and spasms but only during her sleep. I had the dog tested with kinesiology, and she tested for a food enzyme formula with bile salts. She gets one capsule every other day, she's stopped begging for food everyday, she lost a little weight, and I'm waiting to hear when her spasms stop.
Also useful is The KI Method for seizures, in people you hold both thumbs to stop a seizure in progress, or even ahead of time to help prevent. So in a puppy I guess you could hold the two front paws, one in each of your hands.
