I have an 8 month old female Yorkie with very similar symptoms.
We first noticed this when she was six months old. We thought she might have picked up/eaten something poisonous and this was just a reaction to it, because she vomitted. She has shaking episodes where she is very wobbly on her feet, espeacially her rear end, and has fallen down. When having an episode she holds her head/ears in a peculiar way. She has been very difficult to toilet train. I wonder if one of her pupils is bigger than the other. After an episode she sleeps and wakes up just fine, except she favours her left back leg. Sometimes she favours her left back leg off and on for a week. She has had a blood work up,(fine) thyroid checked out, and x rays (no hip or patella problem). She has gone weeks without an episode. She had an episode last night, first in about a month. We kind of hoped she was over it! She is lean but not skinny, she is very active, happy, loving, friendly and very outgoing.(except during/after an episode. I sometimes wonder if she has a screw loose, or maybe not to bright! She could just be strong willed! I wish she could talk! My second vet has given her omega 3-6-9 supplement and high potency multiple vitamin/ minerals. He says seizures can be controlled by diet??? I am VERY interested in Jack's problem and hope he is on the road to recovery. Please keep us updated.
