I have been riding him VERY often, 4 or 5 times a week/1-2 hours per ride (if not more) and while riding today I noticed a "clacking" sound as he walked. It almost sounded like a "popping". I am sorry if these descriptions don't make sense but please bare with me. I dismounted and checked his hooves to see if perhaps there was a lodged rock or something, but nothing. The clacking noise seemed to only come from his left side, and sometimes it would be his front left clacking and then others it was his back left. I have never noticed this before, and he did not do it when trotting or cantering on the ride, only at the walk. It was even noticeable as I led him to his pasture at the end of the day (once again only on his left side). I have done some online research and I feel like maybe he's forging? He is an Appendix and he does have some lonnng TB legs, but his back is not that short. He is about 16.2/16.3h and he is 7 years old. He is shod on all 4 feet and is due for a trim (farrier is coming this Tuesday)
Should I mention this noise to the farrier? Or is not a big deal and I would be over reacting? One of the major reasons I'm concerned is lately when going down a section of trail which is fairly steep and hard packed dirt/some gravel his hind legs have been slipping out to the side from underneath him. It startles the heck out of both him and me! I at first thought it was just a traction issue but now I am wondering if these two issues are related. Posting a pic of him so if there ARE conformation issues that I am just not seeing, others can help me out :) Thanks!
