Here is the general area... note this is not my horse... I snatched the photo off the internet to show you.
Now could this be from worn out saddle blankets? Do I need to renew the foam under neath the saddle? I know for a fact that my saddle fits him pretty good (its a tad to narrow for him but nothing too horrible).
The bump that happens along there is small and is sometimes in a different spot in the circled area in the photo. It is about not bigger then an inch and is hard to touch. Within the twenty minutes of the saddle being off the bump will go down and his back is back to normal. Sometimes he is sensitive for me to touch it and mess around with it... and other times he has a high pain tolerance or something.
My questions are... what is this from? I think it might be from the saddle resting on his back.... could I fix it by getting the saddle off his back more with blankets? Or are there fancy lifting devices that I can by to put between the saddle and the blankets? Or should I get my saddle re foamed underneath?
