back from the vets....She ran blood work...CBC/Chem/T4/UA...not quite sure what these are...and also checked his blood glucose level which was fine but, he ate before we left....so...that could have been inconclusive...she was thinking maybe hypoglycemic  episode....She will be out of the office tomorrow but another vet will be there so I will call and get the result of the blood work....She did a neurological test on him and said she feels it wasn't a seizure. he has luxtating patellas in both back legs which could be the reason for his legs going out from under him when he is running around. If these tests come back normal...Bentley will have to go to the hospital 

 and spend the day...she will be doing bile acids testing....she is leaning toward liver shunt 
 
   ... Bentley is 8 months old and weighs 3.7 lbs so he isn't a big boy....he is very thin...but all the breeders dogs were like this....so I'm thinking maybe not?  PRAYING it's not!...
