I know I've seen people on the Addison's dogs forum there talking about it in the past. There's a lot of good info on the A-dogs group page so I'd guess there might be some good info on this one too.

She's not a gulper when she drinks, though, so that may have something to do with her being able to share the other dogs' water bowl. I also soak her food in water, so she gets a lot of fluids that way, as well. A friend had to give her dog crushed ice because he couldn't keep water down, so snow is probably a good wintertime alternative.

most pets should drink 28 milliliters (one ounce) of water for every pound they weigh. This means that a 40-pound dog needs about one liter (about one quart) of water every day.
Best of luck...also the snow is not a good idea for normal dogs and worse for ME dogs as very cold substances can effect mega E.

My dog's case, although manageable, is still on the severe end of the spectrum, since she is now six years old and her condition has not improved over time. That is, she still regurgitates every time she is not fed properly. There are varying degrees of severity with this disorder and some of the measures mentioned on that site may be necessary for the most severe cases, but at least in my experience, it's not the norm.

Unless the dog has a ring stricture, it will take seconds, not 20+ minutes, for everything to reach the stomach. Dogs with only megaesophagus and no strictures inhibiting swallowing typically do not need to be restrained in a vertical position after eating. We have Mattie trained to stand at her bowl for a few seconds after she finishes. Usually, she burps and then gets down.

I know a lot of people do it because they read that it was necessary, but for most dogs, it's really not. As uncomfortable as it is for dogs to eat in a Bailey chair and be restrained in it afterward, I wouldn't want to put a dog through it multiple times a day if it wasn't necessary. My vet initially recommended that very thing, and we were prepared to do it. But, the person I got the dog from had rescued more than a dozen dogs with megaesophagus over the years, and she explained how vets tended to be overzealous in their treatment recommendations and shared her successful methods. I talked it over with my vet, who agreed that we could try some alternatives. My vet now recommends those alternatives first and hasn't had a dog who actually needed a Bailey chair since.

HOLLIGATOR, In regards to your above statement i'm assuming you mean an vascular ring anomaly, but that is not the only stricture that can occur with dogs and Mega E.
it's also not just about getting the food to the stomach but allowing enough time for the food to stay in the stomach to do it's duty in the digestive process, especially if if the Mega E is secondary due to other lower digestive problems.
I do however understand what you are doing is working for your dog, and that is one of the first things to try. But many times it's not enough and further extension of the head and neck and body is required. I feel it is important to mention that the bailey chair is not a horrible thing either. Most dogs do very well in this and it is especially helpful for dogs with aspiration pneumonia issues such as that with this original poster.
