Animal Lover,

Many thanks for the reply and info. Em is much better
and has seemed fine since Friday.
It could possibly be the hypoglysemia because the 1st one was about 5:00 P.M. and this last one was around 6:00 P.M. Both dogs had just finished their supper and I had just gone to the cabinet to get their afterdinner treats. I don't remember what time of day the second one was. Maybe I need to start feeding them twice a day. Anyway, I'll talk to the Vet about it.
She didn't do any blood work, X-Rays, etc. The only thing she did was to keep Em under observation for several hours and give her 1 lithium tablet (at a cost of $25.08). I was so worried, I didn't protest the charge, but will when I go back. It seems that
this Vet, one of 3 in the practice didn't know much. So hopefully I'll be able to see one of the others.
Anyway I will do a lot of investigation!
