No this is how you check for ulcers:
Gastric ulcers in horses - YouTube
The guy in the video is a well known vet who is ALSO an acupuncturist. If you have not seen a GOOD acupuncturist or chiropractor do their thing (and btw, many vets are learning these things in continuing education, as mine has, and apparently the vet in the vid) you are missing out on some great tools. Granted calling yourself an equine acupuncturist and being a good one are not the same thing. I don't know a ton about this stuff, but I do know horses and horse handling. The way this guy handled the horse kicking at him tells me quite a bit. He also describes why scoping is an incomplete diagnosis.
And as far as the horse in quastion, it may have ulcers (which can be determined by a gastraskopi) but the symptoms described is a bad back.
how definitive a diagnosis over the internet! IMPRESSIVE!!!
What is it with horse people that they are always off in never never land looking for problems where there aren´t any?
Glad to see I could amuse you. That was certainly why I took the time...
