Thanks to everyone who responded to my post! You guys are a great asset!
After having the vet come out and do a foot,mouth, and eye exam as well as
watch me ride and examine saddle fit - turns out it was the saddle fit
pinching the withers, making him sore, etc..... Needless to say, I've now
got a great "dansk" (know I spelled that wrong) 16 1/2" close contact jump
saddle for sale!!!! Thanks again!!!
