Thanks so much for your reply.  This info. is life saving and I really appreciate your sharing.  It is so scary when these little guys get sick.  The first day we had our Buddy Reagan home he went into a coma state and we didnt know   their blood sugar drop is a condition which seems to be quite frequent  . I know we were stressed and freaked out for a few days running him to the vets where he received Ivs.  Then for a day or two he would be ok, then darn, if it didnt happen again!  
Finally someone told us what was going on and to give him a few drops of karo syrup and bring his body temp. back up by wrapping  him in blankets .  He did outgrow it quickly but, what a trying time .

 But gosh they are so lovable and sweet, they are worth every gray hair!  (Ours not theirs!)  Thanks again , Blessings, Buddys Owner
