Time to show off my project for someone :). A friend’s dog called Poppy has a condition called megaesophagus. In short—the muscles of the esophagus don’t work properly and can’t push what the dog eats down into the stomach. The food gets stuck in the esophagus, and in the best-case scenario, the dog regurgitates it after a while. In the worst case, the dog chokes.
The way to deal with this is to feed the dog in an upright position so that the food falls into the stomach by gravity. A piece of furniture called a Bailey chair is used for this purpose. Since it has to be sized to fit a specific dog, and the condition itself is (fortunately) rare—there are no ready-made versions on the market.
And that’s exactly the kind of chair I made: with adjustable door and tray heights, the ability to open and lock them in a 180-degree open position so they can serve as a water bowl in addition to feeding, and the ability to fold it down fairly easily for flat transport.
