Here come the gray hairs for you Samantha Puppy. Babies will do that to us moms! Your doctor is giving you good advice as far as just worrying about keeping him hydrated for now. About 2 1/2 years ago my grandson caught the horrible stomach virus that ran through our entire family and extended family. It was everywhere here in NJ it seemed! He couldn't keep anything down - not even simple water. His eyes were literally shrunken in and I was frightened beyond words. The doctor just suggested an ounce of water every 15 minutes or so. If that didn't work he would have needed to be hospitalized. It did work and eventually the bug passed. Tiny bits of liquid are important. Food will come later but keeping him hydrated is most important. Poor little guy. Prayers for Aiden from the entire PT family going up!
