Episodes

My 2.5 yro YorkiePoo has had episodes where she frantically runs, then can't stand, pants, salivates thick, potato smelling liquids, legs go outright & stiff, looks bewildered, can't respond to my voice. She pants, salivates & sweats again. She throws up & then comes out of it and is back to normal. *I have videos but I can't attach them.*

Hello - this dog needs to be seen by a vet as soon as you can.  Please do take the means with you to show them the videos. I cannot visualise exactly what is going on, but it certainly sounds concerning.  I wondered about rhabdomyolysis (although your dog doesn't look to be a typical breed at all); also some unusual presentations of fitting, or even hypoglycaemia (low blood sugars).  Finally, there are forms of liver disease that can have secondary affects on the brain.  I hope that it is none of these things, but as every possibility that occurred to me is quite serious, this is definitely worth looking into.
