I should have mentioned the adult onset as well.  The hereditary  condition 
in puppies that is identified at weaning is what I was making  reference to 
as being autosomal recessive inheritance. It is thought that there  is an 
incomplete nerve development in the esophagus that controls the movement  of 
food down the esophagus (peristalsis) in this inherited condition of  
puppies. There is also a condition that develops in the older dog that is  also 
termed megaesopagus, which is secondary to thyroid etc as Zoe said  below.

Subject: Megaesophagus

Megaesophagus is a condition in  humans, cats and dogs where peristalsis 
fails to occur properly and the  esophagus is enlarged.  

Megaesophagus can occur at any age as a  puppy, or as an older dog. If it 
afflicts a puppy, the cause is usually  genetic, or can be due to a 
surgically repairable condition called PRAA  (Persistant Right Aortic Arch). If 
not 
secondary to another disorder in adult  animals, it is called "idiopathic" 
(cause unknown). Megaesophagus can be  secondary to other diseases such as 
Myasthenia Gravis, Thyroid, Addisons and  other Neurological disorders.
