Haven't heard about it in puppies but have a friend who suspects her 6 yo Flat coat may have it.

Is the pup upchucking? Could be (more likely) Megaesophagus if so.

yes it has been, it's congenital in some breeds. It seems to occur again in the acquired form with greater frequency about 2-3 years old, and again later in life, around 10 years old.
megaespophagus is most commonly secondary to myasthenia gravis when it occurs in very young dogs.

Interesting. A friend had a whole litter of Tervs affected w/ MegaE. All but one were serious enough to have to be put down by 7 wks. Very very sad. I dont think anyone ever mentioned looking at/for MG. I always suspected that was environmentally caused since all 6 or so of the pups were affected vs 1-2 which is more common w/ genetic causes.
