My bitch has just turned 2 years old and has been fine her whole life...   she had her first litter a few months ago and towards the end of her pregnancy she started fly snapping after eating, i thought maybe as people get it maybe she was experiencing heart burn/indigestion and it would go away after the pups were born. She is still doing it     She is eye screened all clear, so there is no issues with her eyes.... She doesnt do the seizure type movement she just looks at so
