Thank you, all!! Since one of the symptoms are exessive thirst, I am interested to know how much water is "normal" for an 8 month old EM to drink. She has always been drinking a lot of water even as an 8 week old puppy. Right now she consumes around 1 gallon of water per day (give or take a few cups) and if she does not have water available at all times she gets a really dry mouth.
