We have 2 different size endoscopes to allow for direct visual examination of not only your horse’s upper airway but also to reach the stomach and visually diagnose stomach ulcers.   A long ‘tube’ with a light source and ‘camera’ on the end of it is passed through the nostril to the stomach and the image is put on a computer screen.  Pictures and videos can be saved to a disc that you can take home with you.
