This is interesting to me, bc my 3 year old Winston, started doing this recently, he eats very well, and is over 7 lbs, I question if the low blood sugar comes first or the seizure? Don't know, but i have heard that a seizure will lower their blood sugar. I would love to hear if I am the only one with an adult yorkie, not tiny, that eats well has this type of problem. The only advice I have to offer is to use the Karo syrup, or Nutrical to bring the sugar up, but also feed several times daily, to keep it up. I do confine him to the kitchen when we're not at home, to conserve his energy, bc he mostly sleeps when he's alone. But I still think the seizure comes first, but don't know why...
