be prepared for a day or two of the runs too...it should be starting soon, if it's going to start at all. it's not all that great for dogs but he will get over it after a long snoozy day. keep all the water he wants handy for him and easy to get at.

i know it can be scary when it happens but usually they only do it once, if they're going to do it at all, but it will have no lasting effects.

good luck and no worries.
