Congenital Megaesophagus

Hi There,

I have got a 3 month old long legged jack russell puppy, after having him for a few days we noticed he was regurgitating his food a lot, very worried so took him to the vets, they diagnosed it as Congenital Megaesophagus (a floppy esophagus) this means his food goes straight to his stomach so he regurgitates it. He seems to have good days and bad days but not sure if he's suffering, the vet says he's fine apart from that but wonder if we could do more to make him a bit more comfortable. Can anyone help? and give me some pointers on managing it?

Thanks
