My big bodied ISH has been pointing his left front while on cross ties for a few months now. I recognize this as being indicative of navicular because I have seen it many times before. He is not currently lame and hasn't been lame. I had my vet come out and take films because he popped a wicked splint (sound on that too!) so I had her do navicular films as well. His last set of films was 2 yrs ago and on those films we saw a significant assymetrical outside side bone on his left front but no navicular changes. He now has 2 significant lollipops on the left side of the nav bone but the sidebone hasn't changed.
I realize that every navicular case is different, but does anyone have a timeframe of their own horse from when he started toepointing to when he became unsound? I don't really understand why he would toepoint if he's still painfree enough to be sound.
